Professional Applications & Engineering Value

This No. 10 brass flat washer is engineered to address common industrial challenges such as galvanic corrosion, vibration-induced failure, and regulatory non-compliance. The brass material provides inherent resistance to rust and degradation, making it suitable for marine, plumbing, and electrical systems where moisture exposure is frequent. With a Rockwell B60 hardness, it withstands mechanical stresses without deforming, ensuring long-term fastener security in heavy-duty assemblies. The precise flat washer design and inch-based dimensions facilitate easy integration into existing equipment, reducing maintenance downtime. Additionally, compliance with RoHS and REACH standards assures safe use in regulated sectors, from automotive to consumer electronics, while the non-magnetic nature prevents interference in sensitive instrumentation.

Specification Summary & Compliance
