Professional Applications & Engineering Value

Engineered for demanding industrial applications, this 316 stainless steel square washer delivers critical corrosion protection where ordinary fasteners fail. The square configuration provides superior surface contact compared to round washers, effectively distributing clamp load and preventing embedding in soft materials. With its Rockwell B68 hardness rating, this washer maintains dimensional stability under extreme pressure and vibration, making it ideal for heavy-duty machinery, marine equipment, chemical processing systems, and outdoor infrastructure. The precise 0.285" ID ensures perfect alignment with 1/4" screws, while the generous 0.5" width creates a larger bearing surface that reduces point loading and material fatigue. These engineering advantages translate to reduced maintenance cycles and extended service life in corrosive or high-stress environments.

Specification Summary & Compliance

This square washer features inch system dimensions including 0.285" internal diameter, 0.5" width, and thickness ranging 0.114-0.126" for consistent performance. Manufactured to industrial standards for 1/4" screw applications, it maintains precise tolerances for reliable fit and function. The product is fully compliant with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements (updated June 14, 2023, 235 SVHC), ensuring environmental safety and regulatory acceptance across global markets.
