Professional Applications & Engineering Value

This M16 tapered washer delivers critical engineering solutions for demanding industrial applications where vibration loosening and uneven load distribution compromise fastener integrity. The zinc-plated steel construction combined with the precisely engineered taper profile creates an optimal bearing surface that prevents embedding and distributes clamping forces evenly across connected components. The Rockwell B52 hardness ensures the washer maintains its structural integrity under repeated loading cycles, making it ideal for heavy machinery, structural steel connections, and automotive assemblies. The DIN 435 standard compliance guarantees dimensional precision that eliminates installation issues and ensures reliable performance in metric fastener systems. This tapered washer effectively addresses common industrial challenges including joint relaxation, surface damage prevention, and maintaining preload in vibrating environments.

Specification Summary & Compliance

This precision metric tapered washer features an 18mm inner diameter, 32mm width, and tapered thickness from 7.5mm to 2.5mm, specifically designed for M16 screw applications. Manufactured to DIN 435 specifications with dimensional tolerances ensuring perfect fit and function. The washer is constructed from zinc-plated steel with Rockwell B52 hardness for optimal mechanical performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across various industrial sectors without hazardous substance restrictions.
