Professional Applications & Engineering Value

These black-oxide steel flat washers provide critical engineering solutions for industrial assembly challenges. The corrosion-resistant black-oxide surface treatment significantly extends component life in humid or chemically aggressive environments, reducing maintenance frequency and replacement costs. Engineered specifically for No. 8 screw applications, the precise 0.172" inner diameter ensures secure fastening without play, while the 0.375" outer diameter distributes clamping force effectively to prevent surface damage to connected materials. The controlled thickness variation (0.049-0.068") accommodates manufacturing tolerances while maintaining consistent spacing and vibration absorption in mechanical assemblies, automotive components, and electrical enclosures. These industrial washers deliver reliable performance where consistent bolt tension and corrosion protection are essential for operational safety and longevity.
