Professional Applications & Engineering Value

This tension indicating washer solves critical engineering challenges in structural bolting applications where precise preload measurement is essential. The orange tension-indicating dye provides visual confirmation that proper installation torque has been achieved, eliminating guesswork in critical connections for 1/2" screw assemblies. Manufactured from zinc-plated steel, these washers maintain their 15,000 lbs load capacity even in corrosive environments, making them ideal for construction, heavy machinery, and infrastructure projects. The Rockwell C37 hardness ensures the washer deforms predictably under load without compromising the joint integrity, providing engineers with reliable performance data for structural calculations and safety assessments.

Specification Summary & Compliance
