Professional Applications & Engineering Value
These USS flat washers deliver exceptional engineering value through their hot-dipped galvanized steel construction, specifically designed to combat corrosion in demanding industrial environments. The 0.5" ID x 1.25" OD configuration provides optimal load distribution for 7/16" screw applications, preventing surface damage and maintaining joint integrity under heavy loads. The galvanized surface treatment creates a protective barrier against moisture, chemicals, and atmospheric exposure, significantly extending service life in construction, marine, and outdoor infrastructure projects. Manufactured to ASME B18.21.1 standards, these washers ensure reliable performance in structural assemblies, machinery mounting, and pipeline systems where corrosion resistance and dimensional precision are critical.
Specification Summary & Compliance
This USS flat washer features precise dimensional specifications with 0.5" inner diameter, 1.25" outer diameter, and thickness ranging from 0.064" to 0.104". Manufactured in compliance with ASME B18.21.1 standards for dimensional accuracy and performance requirements. The product meets RoHS 3 (2015/863/EU) compliance for environmental safety and is specifically designed for use with 7/16" screw sizes in inch-system applications.
