Professional Applications & Engineering Value
This tension indicating washer addresses critical safety concerns in structural steel connections where proper bolt tension is paramount. The galvanized steel material provides essential corrosion protection for bridges, transmission towers, and industrial facilities exposed to weather elements. The orange tension-indicating dye serves as a reliable visual indicator that immediately confirms when specified preload has been achieved, preventing both under-tightening (which compromises joint integrity) and over-tightening (which can damage threads). With its 64,000 lbs load capacity and compliance with ASTM F959 Type A325 standards, this washer delivers the engineering precision required for critical bolted connections in construction, heavy machinery, and infrastructure projects where failure is not an option.
Specification Summary & Compliance
This tension indicating washer features precise dimensional specifications with 1.155" ID, 2.26" OD, and thickness ranging from 0.158" to 0.270" to accommodate standard 1 1/8" screw applications. Manufactured to exacting ASME B18.2.6 and ASTM F959 Type A325 standards, it ensures consistent performance and interchangeability across industrial applications. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest international standards for restricted substances and chemical safety in industrial components.
