.090 Steel Washer

The .090 Steel Washer by BERT Transmissions is a precision fastener component designed for high-performance transmission builds and rebuild kits. This small but critical component serves as a load-distribution element in transmission assemblies, preventing bolt head embedment and ensuring even clamping force across mating surfaces. Whether you're completing a competition transmission overhaul, restoring a vintage gearbox, or maintaining heavy-duty shift components, this washer provides the OEM-quality fitment that separates professional builds from amateur mistakes.

Manufactured from hardened steel to .090-inch thickness, this washer delivers the structural rigidity required to maintain consistent bolt preload under the cyclic stress of gear engagement and torque transfer. The precise thickness specification prevents galling, maintains proper shim clearances, and protects soft materials like aluminum housings from fastener damage during assembly. BERT Transmissions engineered this component to work seamlessly within their transmission systems, making it an ideal replacement when restoring original components or upgrading critical fastener interfaces in transmission rebuilds where repeatability and precision are non-negotiable.

This washer is essential for transmission enthusiasts, rebuilders, and shops working with BERT Transmissions products or similar high-performance gearbox assemblies. Its compact dimensions (3.25 x 0.25 x 5.5 inches) integrate seamlessly into tight transmission housings without interfering with adjacent components. The minimal weight (0.02 lbs) ensures zero performance impact while the hardened steel composition guarantees durability across repeated shifts, high-RPM acceleration runs, and extreme load conditions. Stock this part for transmission maintenance, engine overhauls, or as insurance against stripped fastener seats in critical transmission applications.
