Professional Applications & Engineering Value
This hot-dipped galvanized iron tapered washer delivers critical engineering solutions for industrial applications where corrosion resistance and load distribution are paramount. The tapered profile (0.344" to 0.156" thickness) compensates for uneven surfaces and angled connections, preventing joint loosening in vibrating machinery and structural assemblies. The Rockwell B62 hardness ensures consistent performance under mechanical stress, while the 0.438" ID provides precise alignment with 3/8" fasteners in construction, heavy equipment, and marine applications. The hot-dipped galvanized surface treatment creates a robust barrier against moisture and chemicals, significantly extending service life in corrosive environments where standard washers would degrade rapidly.
Specification Summary & Compliance
Manufactured to precise inch-system dimensions: 0.438" inner diameter, 1.25" width, with tapered thickness from 0.344" to 0.156". The washer features Rockwell B62 hardness for consistent mechanical performance and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence. Designed specifically for 3/8" screw applications in industrial fastening systems requiring reliable corrosion protection and dimensional accuracy.
