Value Collection R63082240 Internal Tooth Lock Washer

Product Description

The VALUE COLLECTION R63082240 is a Grade 410 stainless steel internal tooth lock washer designed for use with 1/4 inch screws. It features an inside diameter of 0.267 inches and an outside diameter of 0.478 inches, with a thickness of 0.028 inches. The internal tooth configuration bites into both the fastener bearing surface and the mating material under load, resisting rotational loosening caused by vibration. Grade 410 stainless steel provides good corrosion resistance and hardness, making this washer suitable for mechanical assemblies exposed to moisture or mild chemical environments. Licensed tradespeople and assembly technicians across HVAC, plumbing, electrical, and pool equipment applications use this style of washer in standard fastener installations.

This internal tooth lock washer is appropriate for residential and light commercial mechanical assemblies where a 1/4 inch fastener is used and vibration resistance is required. Common applications include equipment panels, junction boxes, pump housings, and structural brackets where maintaining clamp load over time is critical. The internal tooth design keeps the washer centered on the fastener shank and conceals the teeth beneath the fastener head for a cleaner finished appearance.

Key Features

• Internal tooth design resists loosening under vibration without protruding beyond the fastener head
• Grade 410 stainless steel construction offers corrosion resistance and surface hardness
• Inside diameter of 0.267 inches sized for standard 1/4 inch screws
• Outside diameter of 0.478 inches provides adequate bearing surface coverage
• Thickness of 0.028 inches for consistent clamp load distribution

Compatibility

Designed for use with 1/4 inch screws as an internal tooth lock washer in standard mechanical fastener assemblies.

Installation Notes

Install with the teeth facing the fastener head or nut bearing surface, not against the workpiece material, to ensure proper grip. Confirm the mating screw and assembly material are compatible with Grade 410 stainless steel to avoid galvanic corrosion risk. Tighten fasteners to the torque specification required by the assembly drawing or equipment manufacturer. Always follow applicable mechanical codes and equipment service procedures when servicing panels, enclosures, or mechanical assemblies.
