High Force Cordless Shear Wrench

One-Sided Tensioning to Engineered Shear Point, Every Time

Structural steel connections using high-strength friction-grip bolts present a unique fastening challenge: the bolt must be tightened to a precisely engineered tension level, but accessing both the bolt head and nut simultaneously is often impossible on installed structural connections where the back side is obstructed. Shear wrenches solve this by tensioning from one side only, applying torque until a splined collar on the bolt's tip shears off at a pre-engineered force threshold that corresponds exactly to the correct installed bolt tension — removing torque measurement uncertainty from the equation entirely, since the bolt shears at the correct tension by mechanical design rather than calculated torque-to-tension conversion.

Our high force cordless shear wrench delivers 1,100 Nm of shear force from a 20V battery system, calibrated specifically for the M16 to M24 high-strength friction-grip bolt range used extensively in structural steel, bridge, and heavy fabrication connections. Because the shearing mechanism inherently confirms correct installation — a bolt that hasn't sheared has not reached design tension, full stop — this method provides superior installation verification compared to torque-controlled tightening, where torque-tension relationships can vary with thread condition, lubrication, and surface friction in ways that introduce installation uncertainty even when the torque wrench itself is perfectly calibrated.

The tool's reaction system manages the substantial counter-torque generated during the shearing operation through an internal reaction mechanism rather than requiring the operator to physically resist twisting force, a critical safety feature given the torque magnitudes involved in shearing M20 and M24 bolts. The collet jaw assembly that engages the bolt's splined tip is engineered for repeated high-cycle use across full structural connection installations, with replaceable collet components addressing the wear that occurs from the high-force engagement and disengagement cycle inherent to shear wrench operation.

Built for structural steel erectors, bridge construction crews, and heavy fabrication shops working with TC (tension control) bolt systems, this shear wrench eliminates the access and verification challenges of conventional torque-wrench tightening on structural connections. The 20V battery platform provides genuine cordless mobility for steel erection work at height, removing the air hose and compressor logistics traditionally associated with pneumatic shear wrenches. For connections engineered around tension-control bolt systems, this tool delivers the precise, verifiable installation that structural integrity demands.
