Professional Applications & Engineering Value
These SAE flat washers manufactured from zinc-plated steel deliver critical engineering solutions for industrial assembly challenges. The precise 0.125" inner diameter creates perfect alignment with No. 4 screw applications, eliminating play and preventing thread damage during torque application. The zinc plating provides essential corrosion resistance in environments exposed to moisture or chemicals, while the SAE inch standard ensures compatibility with existing tooling and components. These flat washers effectively distribute clamping force across a 0.312" diameter, protecting sensitive materials from indentation and maintaining the integrity of fastened joints in electronic enclosures, machinery assemblies, and automotive components where reliable, vibration-resistant connections are paramount.
Specification Summary & Compliance
This SAE flat washer features precise inch dimensions with 0.125" ID, 0.312" OD, and thickness ranging 0.020-0.040". Manufactured from zinc-plated steel for consistent performance, the washer complies with SAE standards for inch fasteners and carries full RoHS 3 (2015/863/EU) compliance certification, ensuring environmental safety and meeting international regulatory requirements for hazardous substance restrictions.
