Wera Click-Torque Wrenches: Which Size Do You Need?

Wera is a German toolmaker known for colorful, carefully designed hand tools, and its Click-Torque wrenches bring that same attention to detail to tightening bolts correctly. A torque wrench lets you tighten a bolt to an exact force instead of guessing. Torque is twisting force, measured here in newton-meters (Nm). You set the number the manual asks for, pull the handle, and the wrench gives a click you can hear and feel when you reach it. That protects parts from being too loose, which lets them work free, or too tight, which can strip threads or crack parts.
The six Wera tools here differ mainly in drive size and torque range: the A 5 and A 6 cover 2.5-25 Nm with a 1/4″ drive (the A 6 as a 20-piece set), the B 1 and B 2 cover 10-50 and 20-100 Nm with a 3/8″ drive, the C 3 covers 40-200 Nm with a 1/2″ drive, and the Kraftform 7440 is a torque screwdriver for tiny settings from 0.3 to 1.2 Nm.

Wera Click-Torque A 5 for Bikes and Small Fasteners
Wera
Wera Click-Torque A 6 Torque Wrench Set, 2.5-25 Nm, 1/4" Drive, 20 Pc
Price and specifications are read from the Amazon product page and can change.
Wera Click-Torque A 6 Torque Wrench
Best for: Gift set ready to use
Pros
- 20-piece set with case
- Sockets 6-13mm and bits
- Free-turning extension
Cons
- ±4% accuracy
- Low 25 Nm maximum
The Wera 05075604001 CLICK-TORQUE A 5 TORQUE wrench covers 2.5 to 25 Nm with a 1/4″ square drive. The square drive is the square peg that sockets push onto; 1/4″ is the smallest common size, suited to small bolts. It uses a 45-tooth reversible ratchet, so you can tighten with torque control clockwise and switch direction to loosen.
Setting it is simple: turn the handle to your value, and you feel and hear clicks as you pass each scale mark, which helps you set it precisely. When you reach the set torque while tightening, a separate release click tells you to stop. The listing states accuracy of ±4% per DIN EN ISO 6789-1:2017-07, an international standard for torque tools, and an ergonomic two-component handle for right-hand use. It is 12.8 inches long. The weight shown, 0.01 kg, is clearly a listing error.
This range fits jobs where small bolts need gentle, exact force, such as many bicycle components, small engine covers and equipment fasteners. Check the torque figures printed on your part or in its manual. If you want sockets and bits in the box, the A 6 set is the same range with accessories included.
Wera Click-Torque B 2 for General Car Work
The Wera Click-Torque B 2 covers 20 to 100 Nm with a 3/8″ square drive, a mid-size drive used for a lot of car and engine work. It has the same 45-tooth reversible ratchet, setting clicks, release click and right-hand ergonomic handle as the rest of the Click-Torque range, and the listing states ±3% accuracy to DIN EN ISO 6789-1.
It measures 17.52 inches and weighs 1.25 kg. Its range overlaps the B 1 at the low end and the C 3 at the top, which makes it a versatile middle choice for someone who works on many different bolts under the hood.
Choose the B 2 for a home mechanic who wants one wrench for a broad range of general automotive jobs. Heavy-duty jobs above 100 Nm call for the C 3.
Wera Click-Torque B 1 for Motorcycles and Mid-Range Jobs
The Wera Click-Torque B1 Torque wrench Drive 10-50 Nm uses a 3/8″ square drive and the same Click-Torque features, with ±3% accuracy and a 45-tooth reversible ratchet.
It is 15.55 inches long and weighs 2.3 pounds. Its 10-50 Nm range sits between the A 5 and B 2, which makes it a good fit for mid-sized fasteners where 25 Nm is not enough but 100 Nm is more than you need.
Choose this for motorcycle maintenance or mid-range car work. Its listing shows a solid end rather than the hang hole found on the other Click-Torque wrenches, a small detail if you like to hang tools on a pegboard. For wheel nuts, look to the C 3.
Wera Click-Torque A 6 Set for a Ready-to-Use Gift
The Wera Click-Torque A 6 Torque Wrench Set is a 20-piece kit built around a 2.5-25 Nm wrench with a 1/4″ drive, ±4% accuracy and a 45-tooth reversible ratchet. The listing says it includes a 1/4″ socket adaptor, a free-turning extension, six 1/4″-drive sockets from 6 to 13mm, and Phillips, TORX and hex bits; the description mentions 11 Hex-Plus hex bits.
The listing adds that the sockets are rated for hand tools and non-impact power tools. It is 33.5 cm long. The listed weight of 0.11 kg and the “28” voltage field look like listing errors.
This is the best gift choice for a cyclist or hobbyist who does not own sockets yet. For more Wera kits, see our guide to Wera tool sets.
Wera Click-Torque C 3 for Wheel Nuts and Big Bolts
The Wera Click-Torque C 3 covers 40 to 200 Nm with a 1/2″ square drive, the largest in this lineup. It has the same reversible 45-tooth ratchet, setting and release clicks, and ±3% accuracy.
It is 21.06 inches long and weighs 1.46 kg; the longer handle gives leverage for high torque. That range is the one people usually reach for with car wheel nuts and suspension bolts, though you should always use the figure in your vehicle manual.
Choose the C 3 for tire changes and heavy car work. It is too large for small or delicate fasteners.
Wera Kraftform 7440 Torque Screwdriver for Delicate Screws
The Wera 05074700001 Kraftform 7440 Hexagon Torque Screwdriver is not a wrench but a torque-limiting screwdriver. It sets from 0.3 to 1.2 Nm in 0.05 Nm steps, with ±6% accuracy to DIN EN ISO 6789, and clicks when the preset torque is reached.
A Rapidaptor quick-release chuck swaps 1/4″ hex bits in seconds, the Kraftform handle has hard and soft grip zones, and a hexagonal body keeps it from rolling off the bench. A numerical scale shows the setting clearly.
Choose it for electronics, small assemblies and furniture hardware where very low torque matters. The listing explains why this matters: too little torque and a joint works loose, too much and you strip a thread or crack a housing. For bigger bolts, pair it with one of the Click-Torque wrenches above.
How to Choose the Right Wera Torque Wrench
- Find your torque number first. Look up the Nm values in your manual, then choose a tool whose range covers them comfortably in the middle. Wrenches are generally most comfortable to use away from the very bottom of their scale.
- Match the drive size. 1/4″ for small work (A 5, A 6), 3/8″ for general car work (B 1, B 2), 1/2″ for big bolts (C 3).
- Accuracy. The B 1, B 2 and C 3 list ±3%; the A 5 and A 6 list ±4%; the 7440 screwdriver lists ±6%.
- Set or single tool. Only the A 6 includes sockets and bits. If you are comparing Wera with a budget torque wrench, weigh the certified accuracy and ratchet quality.
FAQ

Newton-meters, the unit of twisting force. Higher numbers mean tighter.
