Why use a torque control arm

Torque Control Arm systems absorb the torque produced by assembly tools reducing operator fatigue and increasing overall productivity while balancing the tool’s weight.  A second benefit is that many torque control arms hold the screwdriver to a 90 degree angle to the fastener assuring that the fastener is inserted straight without any cross threading issues, reducing the chance of damaging the work parts.


Assembly work-sites poorly arranged lead to potential injuries and expenses. Risk factors increase when operating high speed power tools. Manufacturers in large and small facilities often use power tools for tightening fasteners. When power tools produce an unwanted torque reaction that transfers to the assembler’s hand repetitively can cause stress injuries over time. This sudden transfer of force and sufficient exposure could result in the wrist can being injured.

Express Assembly Torque Control Arms will increase productivity and reduce manufacturing costs. Our Torque Control Arms will reduce the twist on the operator’s hand and operator fatigue.

Industry standards recommended for torque control arms being used:

For women torque over 40 in-lbs and for men torques over 60 in-lbs


Position control – Torque Control Arms ensure that the screwdriver’s bit makes a 90 degree angle to the fastener reducing the chance of damaging the work parts. Your Express Assembly torque control arm will keep your work area clean and uncluttered.
