Professional Applications & Engineering Value
These zinc-plated steel SAE flat washers deliver critical engineering solutions for industrial assembly challenges. The 0.141" ID provides precise alignment with No. 5 screws, eliminating misalignment issues that compromise fastener performance. The zinc plating creates a sacrificial barrier that significantly extends service life by preventing galvanic corrosion in humid or chemically aggressive environments. With 0.281" OD and controlled thickness between 0.020-0.040", these washers effectively distribute clamping forces across wider surface areas, preventing material deformation in soft substrates and maintaining joint integrity under vibration and thermal cycling. Ideal for machinery assembly, electrical enclosures, and general hardware applications where reliable, compliant components are essential.
Specification Summary & Compliance
Manufactured to SAE standards with inch system measurements featuring precise 0.141" internal diameter and 0.281" outer diameter. Thickness tolerance maintained within 0.020-0.040" range for consistent performance. Constructed from zinc-plated steel for enhanced corrosion protection. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications.
