Value Collection 742096PS M8 Internal Tooth Lock Washer

Product Description

The VALUE COLLECTION 742096PS is an internal tooth lock washer designed for M8 screw applications. It features a spring steel construction with a zinc-plated finish, providing corrosion resistance and reliable holding force under vibration. The washer measures 8.2mm inside diameter and 14.0mm outside diameter, with a 0.8mm thickness. The internal teeth bite into the mating surface and fastener head to resist loosening in bolted assemblies. This is a Grade 2 material specification part suited for general industrial, mechanical, and electrical panel assembly work where standard tooth lock washers are required.

Internal tooth lock washers in this size class are commonly used in light to medium-duty mechanical assemblies, electrical enclosures, and equipment panels where M8 fasteners are specified. They are installed between the fastener head and the workpiece surface to maintain clamp load under dynamic or vibrating conditions. The zinc plating makes them suitable for indoor and low-exposure environments where mild corrosion resistance is needed.

Key Features

• Internal tooth design grips both fastener head and mating surface to resist loosening
• Spring steel construction provides consistent preload retention across the tooth profile
• Zinc-plated finish adds mild corrosion resistance for general service environments
• Fits M8 screws with 8.2mm inside diameter bore
• Grade 2 material specification for standard industrial fastening applications
• Compact 14.0mm outside diameter fits standard M8 fastener seat geometry

Compatibility

Designed for use with M8 screws and bolts in general industrial and mechanical fastening applications requiring an internal tooth lock washer with an 8.2mm bore.

Installation Notes

Install the lock washer between the fastener head and the workpiece surface with the teeth facing the fastener head. Ensure mating surfaces are clean and free of debris before assembly to allow full tooth engagement. These washers are single-use components and should not be reused after the fastener has been fully torqued, as the teeth may deform and lose holding effectiveness. Follow applicable assembly standards for the application when specifying final torque values.
