Value Collection 05WE External Tooth Lock Washer 5 Screw

Product Description

The VALUE COLLECTION 05WE is a 5 screw external tooth lock washer designed to prevent fastener loosening under vibration and dynamic loads. It features a 0.136 inch inside diameter and a 0.285 inch outside diameter, with a thickness of 0.019 inch. Constructed from Grade 2 spring steel with a zinc-plated finish, this washer delivers solid corrosion resistance and consistent spring tension. Hardness is rated at 40 to 50 HRC, giving it the bite and resilience required for reliable locking action. It is installed by mechanics, maintenance technicians, electricians, and plumbers wherever screw-size fasteners require positive retention.

This external tooth lock washer is suited for light to medium-duty fastening applications across electrical panels, equipment enclosures, HVAC assemblies, plumbing fixtures, and general mechanical assemblies. The external tooth design maximizes contact area with the mating surface, making it appropriate for use with standard 5 screw hardware in both residential and commercial maintenance scenarios. It is typically used in applications where surface finish damage from the teeth is acceptable and where vibration resistance is a priority.

Key Features

• External tooth design bites into mating surface to resist rotational loosening under vibration
• 0.136 inch inside diameter sized for 5 screw fasteners
• Spring steel construction rated at 40 to 50 HRC for consistent locking force
• Zinc-plated finish provides corrosion resistance in typical indoor and light outdoor environments
• 0.019 inch thickness fits standard countersunk and flat applications without excessive stack height
• Grade 2 material meets general-purpose fastening requirements

Compatibility

Designed as an OEM-style replacement or new-installation washer for use with 5 screw fasteners in general mechanical, electrical, HVAC, and plumbing assemblies requiring external tooth lock washer retention.

Installation Notes

Install with the teeth facing the fastener head or nut, not the base material, unless the application requires grounding contact. Ensure mating surfaces are clean and free of debris before seating the washer. No special tools are required beyond standard hand or power drivers. Always follow applicable codes and equipment manufacturer torque guidance when assembling fastened joints.
