This is an incredible price for a precision product and includes a hard case, a medium-length extension bar, a 1/2in-3/8in adapter and other extras. Accuracy is better than many more expensive rivals, but imperial torque scales aren’t catered for and the tool supplements the sensible Nm scale with the hard-to-use, decimalised kg.m. The adjuster gets very stiff when high torque figures are being set, too.

Price £21.
