Professional Applications & Engineering Value

These SAE flat washers in Black-Oxide 18-8 Stainless Steel address critical industrial challenges where corrosion and mechanical stress compromise fastener integrity. The 1.062" ID x 2" OD design ensures even load distribution across 1" screw connections, preventing joint loosening in vibrating machinery, structural frameworks, and outdoor equipment. Engineered to ASME B18.21.1 standards, they deliver predictable performance in automotive, construction, and marine applications—eliminating galvanic corrosion risks while maintaining dimensional precision under high-torque conditions. The black-oxide surface enhances lubricity, reducing installation friction and extending service life in heavy-duty washers scenarios.

Specification Summary & Compliance

This flat washer conforms to ASME B18.21.1 dimensional tolerances with an inner diameter of 1.062", outer diameter of 2", and thickness between 0.108-0.160". Manufactured from 18-8 Stainless Steel with a black-oxide finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for hazardous substance restrictions. The washer is designed for use with 1" screws in inch-system applications, though hardness is not rated for specific mechanical properties.
