Wera torque wrench buying guide

Updated: October 2026

You are looking at eleven Wera Click-Torque wrenches on amazon.co.uk, from the A 6 at about £133.20 to the C 4 at about £199.99, and the green handles look alike. A Wera torque wrench buying guide has to settle the fastener’s newton-metre figure, the drive and the direction before any star rating is useful. This page is that order of checks. It does not name a winner. The listings are in the [Wera torque wrench comparison](/hub/hand-tools/wera-torque-wrench). The Products Compared editorial team used those listings and Wera’s Click-Torque manual. There was no laboratory test. If you buy through our links, we may earn a commission at no extra cost to you.

Put the fastener’s Nm inside the printed range

The first check is whether the number on the bolt, or in the maker’s note, sits inside the range printed on the wrench. The A 5, the A 6, the A 6 set and the Bicycle Set Torque 1 are 2.5–25 Nm. The B 1 and the C 1 are 10–50 Nm. The B 2, the C 2 and the C 2 Push are 20–100 Nm. The C 3 title is 40–200 Nm. The C 4 is 60–300 Nm. A 20 Nm clamp fits an A-series window and does not fit a C 3, which starts at 40 Nm. A figure of 110 Nm can sit in the C 3 title or the C 4, and it cannot sit in a C 2 that ends at 100 Nm. Drop any wrench whose printed ends do not contain the figure. An adaptor does not raise that window. Wera’s manual also lists a C 5 and an E 1. Neither is in this extract. Wheel figures stay on the wheel-nut page. If you already know the job, the best Wera torque wrench page names one listing per job.

Match the drive, then read the direction line

Once the range fits, the socket or bit has to fit the drive. The A 5 and the bicycle set are 1/4 inch square. The A 6 and the A 6 set are 1/4 inch hex. The B 1 and the B 2 are 3/8 inch square. The C 1, C 2, C 2 Push, C 3 and C 4 are 1/2 inch square. A 1/2 inch wheel socket will not seat on a 1/4 inch square. An adaptor you already own still does not change the newton-metre window. Bicycle marks are on the bicycle page. Reversible, on most of these listings, describes a ratchet that flips so you can undo a fastener. It does not say the wrench measures torque anti-clockwise. Only the C 2 Push states clockwise and anti-clockwise control, by reversing a captive square, and only from 20 Nm to 100 Nm.

Read the percentage that is actually printed

Wera’s Click-Torque manual states ±4% for the A 5 and the A 6, and ±3% for the rest of this family where the claim is made. The A-series amazon.co.uk bullets repeat ±4%. The B 1 and C 3 bullets omit a percentage, while Wera’s pages for those models state ±3%. Do not paste another shop’s figure onto the Amazon bullet. Halfords has described an A 5 as precise to 1/4%. The manual says ±4%. ISO 6789-1:2017 is the declaration of conformance Wera says ships with the wrench, not a UKAS certificate to ISO 6789-2. The Measuring Instruments Regulations 2016 do not list a hand torque wrench.

Ignore a cell that cannot be the tool

The C 3 title and short bullet say 40–200 Nm. The included-components line on the same listing says 40–300 Nm. Wera’s C 3 page states 40–200 Nm. Do not set a fastener as if the title had been rewritten. The C 4 is the wrench whose printed window runs to 300 Nm, and it starts at 60 Nm, so a 50 Nm bolt is below it. An A-series weight cell of 11 g, a B 1 length cell of 1 cm, a C 3 length cell of 12.7 cm and a C 4 length cell of 3.81 inches are not these tools. Wera’s A 5 datasheet gives about 290 mm and 551 g. After the four checks you should have a shortlist, not a champion. Setting the green line is the how to use page.

Common questions

Which check comes first, the star rating or the newton-metre window?
The newton-metre window comes first. Compare stars only after the printed range contains the figure, the drive fits, and the direction line matches the thread.
Does a reversible ratchet mean the wrench measures anti-clockwise?
No. Reversible, on these listings, means the ratchet can be flipped to undo a fastener. Measurement the other way is a separate claim. Only the C 2 Push states clockwise and anti-clockwise torque control. The other rows say right-hand use, or they stay silent.
Why do the A 5 and A 6 say ±4% when other models say ±3%?
Because that is what Wera prints for those two models. The manual gives the A 5 and A 6 as ±4% and the rest of this family as ±3% where the claim is made. The B 1 and C 3 Amazon bullets leave the percentage out. A 1/4% line is not the manual.
The C 3 title says 40–200 Nm and the included line says 40–300 Nm. Which is the conflict?
Both lines are on amazon.co.uk listing B07B7XXQHT. The title says 40–200 Nm. The included-components line says 40–300 Nm. Wera’s C 3 page states 40–200 Nm. The C 4 is the wrench whose title runs to 300 Nm.
Is ISO 6789-1 a calibration certificate?
It is the standard behind the declaration of conformance Wera says is supplied with the wrench. A certificate to ISO 6789-2 is a separate laboratory document. The 2016 measuring-instrument regulations do not list this hand tool. The paper in the box is not that certificate.
