Professional Applications & Engineering Value

This zinc-plated steel split lock washer delivers critical vibration-resistant performance in industrial applications where mechanical fasteners face constant dynamic stresses. The standard split lock design creates continuous spring tension that compensates for thermal expansion, material relaxation, and vibration-induced loosening. Engineered specifically for No. 6 screw sizes with precise 0.148" internal diameter, it ensures perfect fitment while the 0.25" outer diameter provides optimal surface coverage. The Rockwell C38 hardness maintains structural integrity under repeated loading cycles, making these industrial washers ideal for machinery assembly, automotive components, electrical enclosures, and heavy equipment where fastener security is paramount. The zinc plating offers sacrificial corrosion protection, extending service life in challenging environments.
