Professional Applications & Engineering Value
Engineered for heavy-duty construction and industrial machinery, these zinc-plated steel clipped washers solve critical vibration and corrosion challenges in high-stress assemblies. The clipped design provides positive locking against rotation while accommodating space constraints in structural steel connections, conveyor systems, and equipment mounting. With Rockwell B40 hardness, the washer maintains bearing surface integrity under sustained loads, preventing embedment and joint failure. The zinc plating delivers reliable corrosion protection in humid or outdoor environments, while the precise 0.938" ID x 2.25" OD dimensions ensure perfect compatibility with 7/8" fasteners in inch-system applications.
Specification Summary & Compliance
This clipped washer features inch-system dimensions including 0.938" internal diameter, 2.25" outer diameter, 1.922" clipped width, and thickness range of 0.084-0.097". Manufactured to industrial standards with Rockwell B40 hardness for consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance in global markets.
