Professional Applications & Engineering Value

Our aluminum flat washer delivers exceptional engineering value through its corrosion-resistant properties and precise dimensional control. The 0.26" ID ensures perfect centering on 1/4" screws, eliminating misalignment issues that can compromise assembly integrity. With a 0.5" OD, these washers effectively distribute clamping force across wider surfaces, preventing damage to soft materials and reducing stress concentration points. The aluminum construction provides excellent corrosion resistance without the weight penalty of steel alternatives, making them ideal for aerospace, electronics, marine, and outdoor applications where environmental exposure is a concern. The controlled 0.043-0.057" thickness ensures consistent performance in vibration-prone environments, maintaining bolt tension and preventing joint failure in critical assemblies.

Specification Summary & Compliance

This flat washer features precise inch-system dimensions with 0.26" inner diameter and 0.5" outer diameter, engineered specifically for 1/4" screw applications. The thickness range of 0.043-0.057" ensures dimensional consistency across production batches. Manufactured from high-quality aluminum, these washers comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming they contain no restricted substances and meet current environmental safety standards for industrial and commercial use worldwide.
