Use: • Controlled screw tightening in the range 6-30 N·m / 50-270 lbf·in • For use in almost all industrial manufacturing areas Features: • Classified to DIN EN ISO 6789:2003 Type II Class A, with a factory certificate. Working accuracy: +/- 3 % tolerance of scale set torque. The specification of the standard (+/- 4 %) is exceeded. • 1/4" square drive with ball locking device DIN 3120 - A 6.3 ISO 1174 • Automatic short-path actuation with tactile impulse and audible signal • Dual scale with a scale graduation of 1 N·m and 10 lbf·in Technical advantage/Function: • Lightweight and robust (as housing is made of an aluminium alloy), very workshop-friendly • No inaccuracies whether used with both hands or held away from the handle (as for standard torque wrenches). Both the square drive and fulcrum are on an axis which ensures a high degree of user safety; can be extended to reduce the user's working load. • Extremely low wear attributable to reduced forces in a unique lever mechanism • Forged lever chain from our own quality forge • Maximum precision even when subjected to extreme continuous use • Long life cycles and tool lives • Easy operation - fast and safe torque tightening • Easy adjustment thanks to attractive adjusting button secured against loss at the end of the handle • Single- and double-square drive for controlled bi-directional tightening
