Designed for maximum torque and precision, the box end wrench head features a fully enclosed head that grips fasteners securely on all sides. This design prevents slippage, minimizes the risk of rounding off bolt edges, and provides superior leverage for high-torque applications. Whether working in tight spaces or open areas, the box-end wrench ensures a firm, stable grip, making it an essential tool for assembly, maintenance, and repair tasks. It is ideal for high-torque applications and stubborn fasteners, preventing damage to softer materials.

KEY FEATURES
Interchangeable Head Style
The break-over mechanism minimizes shock to assemblies. Tamper-proof internal adjustment. No external adjustment scale — must be preset using a torque analyzer. Torque ranges 25 ozf.in - 50 lbf.in. Six different colored aluminum handles allow for color coding of specific torque values in production areas. Small and lightweight. Ideal for use in restricted spaces. Handle size: 5 1/2 " L x 9/16" Dia. Interchangeable heads are manufactured with a common center line so the torque setting remains the same when head sizes are changed. Designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO 6789:2003 ( 6% of setting). Breaks-over when preset torque is reached eliminating overtorquing.
