Professional Applications & Engineering Value

This split lock washer delivers critical vibration-resistant performance for industrial assemblies where mechanical stress and thermal cycling threaten fastener integrity. The black-oxide 18-8 stainless steel material provides superior corrosion resistance in demanding environments including marine, chemical processing, and outdoor equipment applications. The standard split lock washer type design creates continuous spring tension that compensates for thermal expansion and vibration-induced loosening. Engineered specifically for No. 6 screw size applications, this washer maintains precise dimensional stability while the inch system measurements ensure compatibility with North American equipment specifications. The combination of material strength and geometric precision solves common maintenance challenges in machinery, electrical enclosures, and automotive assemblies where reliable locking action is essential for operational safety.

Specification Summary & Compliance
