Professional Applications & Engineering Value

These brass flat washers deliver exceptional engineering value where corrosion resistance and electrical conductivity are paramount. The copper alloy composition prevents galvanic corrosion when paired with steel fasteners, making them ideal for electrical enclosures, marine hardware, and plumbing systems. With precise 0.156" ID dimensions specifically engineered for No. 6 screws, these washers eliminate play and distribute clamping force evenly, preventing surface marring on delicate components. The Rockwell B60 hardness ensures they maintain their form under sustained pressure, while the lead-free brass material meets the strictest environmental standards for industrial equipment manufacturing.

Specification Summary & Compliance

This flat washer maintains precise dimensional tolerances with 0.156" inner diameter, 0.312" outer diameter, and thickness ranging 0.049-0.068". Manufactured to inch system standards for compatibility with No. 6 screws, the component features Rockwell B60 hardness for consistent mechanical performance. Full compliance with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloys and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance.
