Value Collection R63082684 External Tooth Lock Washer

Product Description

The VALUE COLLECTION R63082684 is a stainless steel external tooth lock washer designed to secure fastened assemblies against loosening caused by vibration and torque. Built for 1/2 inch screws, this washer features an inside diameter of 0.53 inches and an outside diameter of 0.9 inches, with a thickness of 0.045 inches. Manufactured from Grade 410 stainless steel, it delivers solid corrosion resistance and mechanical strength in demanding environments. Electricians, plumbers, HVAC technicians, and maintenance professionals use external tooth lock washers as a standard component in panel, equipment, and structural fastening applications.

This external tooth lock washer is suited for use in residential and light commercial mechanical and electrical assemblies where vibration resistance is required. The external tooth design bites into both the bearing surface and the fastener, maintaining clamp load under dynamic loading conditions. Typical applications include equipment mounting, electrical enclosures, HVAC unit assembly, and general mechanical fastening where a standard internal or split lock washer is not specified. This item is sold individually but must be ordered in multiples of 100.

Key Features

• Grade 410 stainless steel construction for corrosion resistance in wet or outdoor environments
• External tooth design provides maximum grip on bearing surface to resist loosening under vibration
• Inside diameter of 0.53 inches fits standard 1/2 inch fasteners
• Outside diameter of 0.9 inches with 0.045 inch thickness for consistent clamp load
• Minimum order quantity of 100 units makes it practical for stocking in service vehicles or shop inventory

Compatibility

Designed as a standard external tooth lock washer for use with 1/2 inch screws and bolts in general mechanical, electrical, and HVAC fastening applications.

Installation Notes

Installation is performed by placing the washer on the fastener with the teeth facing the bearing surface before driving the screw or bolt to final torque. Power down or de-energize any electrical assembly before servicing fastened connections. Follow applicable NEC or equipment manufacturer guidelines for fastener torque and hardware specifications. Do not reuse lock washers that have been fully compressed or deformed during prior installation.
