Professional Applications & Engineering Value

These black-oxide steel flat washers deliver critical engineering solutions where corrosion prevention and dimensional precision are paramount. The black-oxide surface treatment creates a protective barrier against moisture and chemical exposure, significantly reducing oxidation in industrial environments. With precise 0.156" ID x 0.562" OD dimensions specifically engineered for No. 6 screw sizes, these washers ensure perfect fitment while distributing clamping forces evenly across fastened surfaces. This prevents joint loosening from vibration and protects sensitive materials from damage during torque application. Ideal for industrial machinery assembly, automotive components, and electrical enclosures, these washers solve common fastening challenges through their combination of corrosion resistance and dimensional accuracy.

Specification Summary & Compliance

Manufactured to standard inch dimensions with 0.156" inner diameter and 0.562" outer diameter, these flat washers maintain consistent 0.120-0.130" thickness for reliable performance. The black-oxide steel construction meets industrial requirements for corrosion protection and durability. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance for industrial applications.
