Value Collection A210032 M8 Lock Washer Stainless 50pk

Product Description

The VALUE COLLECTION A210032 is a stainless steel external tooth lock washer sized for M8 screws. It features an 8.4mm inside diameter and a 15mm outside diameter, with a 0.8mm thickness. Constructed from Grade 18-8 Austenitic A2 stainless steel, it delivers reliable corrosion resistance and mechanical retention in fastened assemblies. The external tooth design bites into mating surfaces under torque, resisting loosening from vibration and dynamic loads. Electricians, plumbers, HVAC technicians, and general mechanical contractors use these washers in equipment mounting, panel assembly, and pipe support applications where a secure, corrosion-resistant fastener interface is required.

This washer is suited for residential and light commercial applications where M8 fasteners are used on steel, aluminum, or stainless substrates. The Grade 18-8 A2 stainless construction makes it appropriate for humid, wet, or mildly corrosive environments such as mechanical rooms, rooftop equipment mounts, pool equipment enclosures, and electrical panel assemblies. Sold in a pack of 50 units, it is a practical stocking quantity for service vehicles and shop inventory.

Key Features

• Grade 18-8 Austenitic A2 stainless steel construction for corrosion resistance
• External tooth design locks against mating surface to resist vibration-induced loosening
• 8.4mm inside diameter fits M8 screws and bolts
• 15mm outside diameter provides broad bearing surface
• 0.8mm thickness for standard fastener stack-up clearance
• Pack of 50 for efficient stocking and field use

Compatibility

Designed for use with M8 screws and bolts in general mechanical, electrical, plumbing, and HVAC fastener assemblies requiring an external tooth lock washer.

Installation Notes

Install with the teeth facing the fastener head or nut, not the mating surface substrate, unless application requirements specify otherwise. Ensure mating surfaces are clean and free of coatings that would prevent tooth engagement. Follow applicable torque guidelines for M8 fasteners per equipment manufacturer specifications. Stainless fastener components can be susceptible to galling under high torque — apply appropriate anti-seize compound if required by the application.
