EZARC Impact Driver Sets: Bits, Sockets or Adapters?

EZARC makes impact-rated accessories: the bits, sockets and adapters that go into an impact driver, not the driver itself. That distinction matters for gift-givers. An impact driver is the power tool that hammers while it spins; these sets are the tips and attachments that let it turn screws, nuts and bolts without snapping. EZARC is known for toughened steel (S2, Cr-V and Cr-Mo), black rust-resistant finishes and sets built around the standard 1/4-inch hex shank that clicks into almost any drill or impact driver.
The six sets below split by the fastener they handle: two adapter kits connect your driver to sockets, one nut driver kit covers small nuts and screws, one 1/2-inch socket set handles larger bolts, and two diamond-tipped bit sets tackle screws, with one aimed at tamper-proof security Torx heads and one covering everyday screw types.
EZARC Impact Driver Bit Sets Compared
| Set | Pieces | What It Drives | Connection | Case |
|---|---|---|---|---|
| EZARC Impact Socket Adapter (14 pcs) | 14 | Sockets via adapters, bits via holders | 1/4″ hex to 1/4″, 3/8″, 1/2″ square | Not listed |
| EZARC 55PCS Magnetic Impact Nut Driver | 55 | Small nuts, wing nuts, screws | 1/4″ hex shank | Blow-molded case |
| EZARC 19PCS Impact Socket Adapter | 19 | Sockets via adapters, bits via holders | 1/4″ hex to 1/4″, 3/8″, 1/2″ square | Not listed |
| EZARC 1/2″ Drive Impact Socket (31 pcs) | 31 | Bolts and nuts, 3/8″–1″ and 10–24mm | 1/2″ square drive | Blow-molded case with handle |
| EZARC Diamond Tip Impact Torx Bit | 10 | Security Torx screws | 1/4″ hex shank | Holder with belt hook |

Two terms you will see a lot. A “hex shank” is the six-sided end that goes into a driver’s chuck. A “square drive” is the square peg that sockets snap onto, sized 1/4, 3/8 or 1/2 inch. Adapters bridge the two, letting a hex-shank impact driver turn square-drive sockets.

EZARC Impact Socket Adapter
Best for: Turning a drill into a socket driver
Pros
- Adapters for 1/4, 3/8 and 1/2 inch
- Three swivel joints plus 105-degree angle
- Quick-release and magnetic holders
Cons
- No bits or sockets beyond one
- No storage case listed
The EZARC Impact Socket Adapter set packs 14 pieces: two quick-release extension bit holders (100mm and 150mm), six socket adapters covering 1/4″, 3/8″ and 1/2″ square drives in lengths from 65 to 150mm, three 360-degree swivel joints, one 105-degree right-angle attachment, one Cr-Mo impact socket and one telescopic magnetic bit holder. Every piece uses a 1/4-inch hex shank.
The listing highlights tool-free bit changes with the quick-release holder, a magnetic extension that grips bits so they do not slip out overhead, and swivel joints that let you drive at an offset angle. The 105-degree angle piece is for cramped spots such as inside cabinets or around a car engine. Material is CRV and Cr-Mo steel with a black electrophoretic (electrically applied) coating that resists rust.
This suits a new drill owner who already has a socket set from hand tools and wants to use those sockets with a power tool. It is the smaller of the two adapter kits; the 19-piece set adds longer 300mm adapters and more magnetic holders. If the recipient still needs the driver itself, look at a drill and impact driver combo kit first.
EZARC 55PCS Magnetic Impact Nut Driver for Nuts and Screws
Ezarc
EZARC 55PCS Magnetic Impact Nut Driver Set, Metric and SAE, 1/4" Hex Shank
Price and specifications are read from the Amazon product page and can change.
EZARC 55PCS Magnetic Impact Nut Driver
Best for: Nuts, screws and HVAC work in one case
Pros
- 55 pieces, metric and SAE
- Magnetic shallow nut drivers
- 20 impact bits plus extension
- Labeled blow-molded case
Cons
- Deep nut drivers are not magnetic
The EZARC 55PCS Magnetic Impact Nut Driver set is the most complete single kit here. It includes 17 magnetic shallow nut drivers (metric 5–13mm, SAE 7/32″–1/2″), 14 deep nut drivers (metric 6–17mm, SAE 1/4″–3/4″), a 12mm wing nut driver, a 6-inch extension bar, two 3-inch Phillips bits (PH1 and PH2) and twenty 1-inch S2 impact bits in Phillips, Pozidriv, Torx, slotted and square styles.
A nut driver is basically a small socket fixed to a hex shank, perfect for driving hex-head sheet-metal screws and small nuts. The shallow ones have strong magnets to hold fasteners; the listing is clear that the deep nut drivers are not magnetic by design. Deep sockets have color-coded collars for spotting sizes quickly, and everything sits in a blow-molded case with labeled slots. Nut drivers and extension are heat-treated Cr-V steel; bits are S2 steel meeting ANSI and DIN standards, with a black manganese phosphate finish.
This is the easiest gift for someone starting out, especially anyone who does HVAC, appliance or auto work where hex-head screws show up constantly. It gives way to the 1/2-inch socket set when bolts get large, such as lug nuts.
EZARC 19PCS Impact Socket Adapter for Extra Reach
Ezarc
EZARC 19PCS Impact Socket Adapter Set with Extensions & Swivel Adapters
Price and specifications are read from the Amazon product page and can change.
EZARC 19PCS Impact Socket Adapter
Best for: Reaching awkward bolts with longer adapters
Pros
- Nine adapters up to 300mm
- Three swivels and 105-degree holder
- Extendable magnetic bit holder
Cons
- Adapters only, sockets not included
- Full contents list cut off in listing
The EZARC 19PCS Impact Socket Adapter set is the bigger adapter kit. It includes nine socket adapters (1/4″, 3/8″ and 1/2″ drive in 65mm, 150mm and 300mm lengths), one quick-release bit holder, three magnetic bit holders, three 360-degree swivel socket adapters, one 105-degree angle bit holder and one extendable magnetic bit holder. The listing’s contents line is cut off after that, so the final piece is not named in the visible text.
The 300mm adapters are the key difference from the 14-piece set: a foot-long extension reaches bolts deep inside an engine bay or behind a panel. It is made from CRV steel with a black manganese phosphate coating for rust and wear resistance, and every piece uses a 1/4-inch hex shank.
Choose it over the 14-piece kit if you often need extra length or more magnetic holders. If you only do light furniture assembly, the 14-piece set covers the same basic conversions. Neither adapter kit includes a full set of sockets.
EZARC 1 2″ Drive Impact Socket for Bigger Bolts
Ezarc
EZARC 1/2" Drive Impact Socket Set, 31PCS SAE and Metric Deep Sockets
Price and specifications are read from the Amazon product page and can change.
EZARC 1 2″ Drive Impact Socket
Best for: Car wheels and heavy bolts
Pros
- 26 deep sockets, SAE and metric
- Three extensions and universal joint
- Ink-filled size markings
Cons
- Needs a 1/2-inch square drive tool
- Deep sockets only, no shallow
The EZARC 1 2″ Drive Impact Socket set is the heavy-duty option. Its 31 pieces include 11 SAE deep sockets (3/8″ to 1″), 15 metric deep sockets (10 to 24mm), three extension bars (3″, 6″ and 10″), a 3/8″-female to 1/2″-male adapter and a 1/2-inch drive universal joint.
The sockets are Cr-V steel; the extensions, adapter and universal joint are heat-treated Cr-Mo for impact resistance. A 6-point design (six contact points inside the socket) grips nuts firmly and is less likely to round them off. Spring-loaded ball detents hold sockets on the extension, and sizes are stamped and ink-filled so they stay readable. It ships in a blow-molded case with a handle.
This set needs a tool with a 1/2-inch square drive, such as an impact wrench, or you would pair it with one of the adapter kits above. It suits car owners changing wheels or working on suspension parts. For small fasteners, the 55-piece nut driver set is more practical.
EZARC Diamond Tip Impact Torx Bit for Security Screws
Best for: Everyday screws in deep spots
Pros
- Torx, Phillips, Pozidriv and slotted
- Longer 2-9/16 inch bits
- Diamond-coated magnetic tips
Cons
- Only one bit per size
- No holder or case listed
Best for: Tamper-proof Torx screws
Pros
- Security Torx TT10 to TT40
- Diamond coating reduces cam-out
- Magnetic holder with belt hook
Cons
- Torx only, no Phillips
- Only nine bits in the set
The EZARC Diamond Tip Impact Torx Bit set targets security Torx screws, the star-shaped screws with a small pin in the middle that are used to stop tampering on appliances, electronics and public fixtures. Bits in this set have a hole to fit over that pin: TT10, TT15, TT20 (two), TT25 (two), TT27, TT30 and TT40, plus a magnetic impact bit holder that brings the count to ten.
A diamond coating on the tips improves grip and helps reduce cam-out, which is when the bit slips out of the screw head and chews it up. The bits are 2-9/16 inches (65mm) long for extra reach, made from CNC-machined S2 steel, and the holder has a hook to clip onto a belt.
This is a specialist gift for someone who repairs appliances or gadgets. It only covers Torx, so anyone needing Phillips or slotted bits should look at the next set. A pocket multi-tool can complement it for quick jobs away from the workbench.
EZARC Diamond Tip Screwdriver Bit for General Screws
The EZARC Diamond Tip Screwdriver Bit set covers the common screw types in one small pack: Torx T15, T20, T25, T30 and T40, slotted SL4.5 and SL6, Phillips PH1 and PH2, and Pozidriv PZ2. Pozidriv looks like Phillips with extra small lines and is common in European furniture.
Like the Torx set, the tips are diamond-coated to reduce slipping, the bits are 2-9/16 inches long (a bit longer than standard 2-inch bits) and they are CNC-machined S2 steel. The listing also mentions a magnetic tip that helps hold screws while you start them. It is labeled for both impact drivers and power drills. The listing does not mention a holder or case.
It suits a first-time drill owner who wants a small, sturdy set of everyday bits. With one bit per size, heavy users may want the larger bit selection in the 55-piece kit, or a broader 1/4-inch bit set.
How to Choose the Right EZARC Impact Driver Set
Start with the fastener. Screws need bits (the two diamond tip sets or the 20 bits in the 55-piece kit). Small nuts and hex-head screws need nut drivers (the 55-piece kit). Bigger bolts need sockets (the 31-piece 1/2-inch set).
Check the tool it goes on. Every set except the 1/2-inch socket set uses a 1/4-inch hex shank for drills and impact drivers. The socket set needs a 1/2-inch square drive, so pair it with an adapter kit if the recipient only owns an impact driver.
Reach and angles. For tight spaces, the adapter kits add swivel joints and a 105-degree angle piece. The 19-piece kit goes longest at 300mm.
Storage. The 55-piece and 31-piece sets come in labeled blow-molded cases, which keeps a gift organized. The smaller sets do not list a full case.
FAQ
Is an EZARC impact driver set a power tool?
No. These are accessories: bits, sockets and adapters for an impact driver or drill. The driver is sold separately.
What does impact rated mean?
Impact-rated accessories are made from tougher, heat-treated steel so they survive the hammering force of an impact driver. EZARC lists S2, Cr-V and Cr-Mo steels across these sets.
Which EZARC set is best for a beginner?
The 55-piece magnetic nut driver set covers the widest range of screws and small nuts in one case, making it the easiest single choice.
Do the socket adapters come with sockets?
The 14-piece set includes one Cr-Mo impact socket. The 19-piece listing does not mention sockets. Both are meant to connect sockets you already own.
What is a security Torx bit?
It is a star-shaped bit with a hole in the center that fits over the pin in tamper-resistant Torx screws. The EZARC Torx set covers TT10 to TT40.
Can I use these bits in a regular drill?
Yes. The 1/4-inch hex shank sets fit most drills and drivers, and the screwdriver bit listing names both impact drivers and power drills.
