Product Details
’Breaking’ Ratchet Handle
From RS PRO, this torque wrench is compatible with 1/4 inch driver bits, and is designed to prevent over-tightening when fastening nuts and bolts. The tool applies a pre-set level of torque before 'breaking', preventing you from potentially applying too much force to a fastener.
This torque wrench works when used either clockwise or anti-clockwise, and is ideal for use in low torque applications.
