Value Collection 742076PS M5 Internal Tooth Lock Washer

Product Description

The VALUE COLLECTION 742076PS is a Grade 2 spring steel internal tooth lock washer designed for use with M5 screws. The internal tooth design bites into both the fastener bearing surface and the mating material to resist loosening caused by vibration and torque. With an inside diameter of 6.62mm (0.261 inches), an outside diameter of 10.0mm (0.394 inches), and a thickness of 0.5mm (0.020 inches), this washer is sized for standard M5 fastener assemblies. The zinc plating provides a basic level of corrosion resistance for general-purpose use. Electricians, HVAC technicians, and mechanical tradespeople commonly use internal tooth lock washers in panel assemblies, equipment enclosures, and structural fastening applications.

This washer is suited for light-duty mechanical and electrical assembly work where vibration-resistant fastening is needed. Typical applications include securing terminal blocks, mounting brackets, control panel components, and equipment covers. The internal tooth configuration makes it a practical choice where the outer diameter of the washer must remain within a confined counterbore or hole pattern. This part does not meet military specifications and is intended for standard commercial and industrial fastener assemblies.

Key Features

• Internal tooth design grips fastener and mating surface to resist vibration-induced loosening
• Grade 2 spring steel construction provides consistent clamp load retention
• Zinc-plated finish for basic corrosion resistance in dry to mildly humid environments
• Compact 10.0mm outside diameter suits confined mounting locations
• 0.5mm thickness for low-profile fastener stack-up
• Sized for M5 screw applications with a 6.62mm inside diameter

Compatibility

Designed as a standard replacement or supplemental lock washer for M5 screw fastener assemblies in commercial and industrial applications.

Installation Notes

Install the lock washer between the fastener head or nut and the mating surface, with the teeth facing the fastener bearing surface. Do not reuse lock washers that have been fully compressed or show deformation, as the spring tension will be reduced. Torque fasteners to the appropriate specification for the application and screw grade. This washer is intended for mechanical assembly by qualified tradespeople following applicable codes and manufacturer fastener guidelines.
