Professional Applications & Engineering Value

This precision steel washer solves critical engineering challenges in industrial applications where exact dimensional control is paramount. The carefully calculated 1.252" inner diameter provides optimal clearance for 1-1/4" shafts, preventing binding while maintaining secure positioning. The substantial 1-15/16" outer diameter creates an expanded bearing surface that effectively distributes clamping forces, protecting sensitive components from deformation under high torque conditions. Manufactured from durable steel material, this inch system washer delivers exceptional resistance to compression set and maintains its structural integrity in demanding environments including heavy machinery, automotive assemblies, and industrial equipment. The tight thickness tolerance ensures consistent performance in multi-washer configurations, making it ideal for precision spacing applications where dimensional accuracy directly impacts equipment reliability and service life.

Specification Summary & Compliance
