Value Collection R63082443 Internal Tooth Lock Washer

Product Description

The VALUE COLLECTION R63082443 is a 4 screw internal tooth lock washer manufactured from Grade 410 stainless steel. Internal tooth lock washers provide a secure, vibration-resistant connection by biting into both the fastener bearing surface and the mating material when torque is applied. With an inside diameter of 0.123 inches and an outside diameter of 0.27 inches, this washer is sized for use with 4 screw fasteners. The 0.019 inch thickness and stainless steel construction make it suitable for applications requiring corrosion resistance. Electricians, HVAC technicians, and equipment assemblers commonly use this style of washer in panel assemblies and equipment mounting applications.

This internal tooth lock washer is used in light-duty fastening applications where preventing loosening from vibration or torque is a priority. Typical applications include electrical enclosures, control panels, HVAC equipment assemblies, and general mechanical assembly work. The Grade 410 stainless steel construction offers good corrosion resistance and hardness, making it appropriate for both indoor and light outdoor service environments where carbon steel hardware is not suitable.

Key Features

• Internal tooth design bites into fastener and mating surface to resist loosening under vibration
• Grade 410 stainless steel construction provides corrosion resistance and durability
• Sized for 4 screw fasteners with 0.123 inch inside diameter
• 0.019 inch thickness suits close-tolerance fastening assemblies
• Suitable for electrical, HVAC, and general mechanical assembly applications

Compatibility

Designed as a standard internal tooth lock washer for 4 screw fasteners in residential and light commercial electrical, HVAC, and mechanical assemblies.

Installation Notes

Installation is performed by placing the washer over the fastener shank so it seats flat against the mating surface before the fastener is driven. Ensure the tooth side contacts the material surface for proper locking action. Power down any equipment or panel before servicing fastened assemblies in electrical or HVAC applications, following applicable NEC and local codes. Do not reuse lock washers that have been fully compressed, as locking effectiveness is reduced.
