Torque Drive Adapter Accurate torque control on a large hexagon can be difficult. BS&B Safety Systems can provide a Torque Drive Adapter for use with all UR-2 Safety Heads (one adapter for all sizes). This adapter permits the use of a standard torque wrench for control of installation load through tightening of the external hexagon nut. The torque drive adapter is available as an accessory. © 2000 BS&B Safety Systems, L.L.C.
