Professional Applications & Engineering Value

These SAE flat washers provide critical engineering solutions for industrial assembly challenges. The black-oxide steel construction delivers exceptional corrosion resistance in humid or chemically exposed environments, while the precise 0.219" inner diameter ensures secure seating on No. 10 screws without play or misalignment. The 0.5" outer diameter effectively distributes clamping force across wider surfaces, preventing material deformation in soft substrates and maintaining joint integrity under vibration. Manufactured to ASME B18.21.1 standards, these washers deliver consistent performance in machinery assembly, electrical enclosures, automotive components, and general industrial fastening applications where dimensional accuracy and environmental compliance are paramount.
