Professional Applications & Engineering Value

This 1/4" aluminum flat washer delivers critical engineering solutions where weight reduction and corrosion resistance are paramount. The Brinell 120 hardness provides optimal balance between malleability and strength, preventing galling while maintaining secure fastening under vibration and thermal cycling. Manufactured to precise inch system specifications with 0.688" OD and 0.265" ID, it ensures perfect alignment and stress distribution for 1/4" screws in aerospace, electronics, and marine applications. The aluminum construction eliminates galvanic corrosion risks when paired with compatible metals, while the controlled 0.030-0.050" thickness maintains consistent clamping force across production runs. These flat washers solve common industrial challenges including weight-sensitive assemblies, electrical conductivity requirements, and environments where ferrous materials would corrode prematurely.

Specification Summary & Compliance

This precision flat washer features inch system dimensions with 0.265" internal diameter and 0.688" outer diameter, manufactured to standard commercial tolerances for reliable performance with 1/4" fasteners. The 0.030-0.050" thickness range ensures consistent spacing and load distribution. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and restricted substance control, meeting the latest international standards for industrial hardware components.
