Value Collection SEWIXX0-4USA-050BX Lock Washer SS316

Product Description

The VALUE COLLECTION SEWIXX0-4USA-050BX is a 4 screw external tooth lock washer manufactured from Grade 316 stainless steel. The external tooth design bites into mating surfaces under load, resisting loosening caused by vibration and torque. With an inside diameter of 0.123 inches and an outside diameter of 0.255 inches, this washer is sized for 4 screw fastener applications. The uncoated Grade 316 stainless steel construction offers strong corrosion resistance, making it suitable for demanding environments including marine, chemical, and outdoor installations. Plumbers, electricians, HVAC technicians, and general mechanical trades use this type of hardware in panel, enclosure, and equipment assembly work.

This external tooth lock washer is suited for light fastener applications in corrosive or wet environments where standard carbon steel hardware would degrade. The Grade 316 alloy provides superior resistance to chlorides compared to Grade 304, making it a common choice for coastal or chemical service locations. It is appropriate for use in control panel assembly, pipe hanger hardware, outdoor electrical enclosures, and similar trade fastening tasks requiring a compact, corrosion-resistant locking washer.

Installation Notes

Install with the teeth facing the fastener head or mating surface to ensure proper locking engagement. Power down or de-energize any electrical panel or equipment before accessing fastener hardware inside enclosures. Use appropriate stainless steel fasteners to avoid galvanic corrosion. Handle stainless steel hardware with clean tools to avoid surface contamination that can reduce corrosion resistance over time.
