Value Collection SEWCIS0-60-100BX Lock Washer 100pk

Product Description

The VALUE COLLECTION SEWCIS0-60-100BX is a 6 screw external tooth lock washer designed to prevent fastener loosening under vibration and dynamic loads. Made from Grade 2 steel with a zinc-plated finish, this washer features serrated external teeth that bite into the mating surface and fastener head to create a secure mechanical lock. The inside diameter measures 0.15 inches, the outside diameter measures 0.289 inches, and the thickness is 0.021 inches. Sold in a box of 100, it is a standard hardware component used by electricians, plumbers, HVAC technicians, and general tradespeople wherever a reliable locking washer is required.

This external tooth lock washer is suited for light-duty fastening applications across residential and commercial construction, electrical panel work, equipment assembly, and mechanical installations. The countersunk feature accommodates flush or recessed seating in appropriate applications. The zinc plating provides basic corrosion resistance for indoor and mildly exposed environments. At a 6 screw size, it fits common small fasteners used in electrical enclosures, HVAC equipment panels, and general mechanical assemblies.

Designed as a standard OEM-style replacement or new-installation external tooth lock washer for 6 screw fastener applications in electrical, HVAC, plumbing, and general mechanical assemblies.

Installation Notes

External tooth lock washers are installed between the fastener head and the mating surface before the fastener is driven to final torque. Ensure the mating surface is clean and free of debris so the teeth can seat properly. Do not reuse a lock washer that has been fully compressed, as the teeth will not re-engage effectively. Follow applicable NEC or equipment manufacturer guidelines when installing hardware inside electrical enclosures or panel assemblies.
