Value Collection A210031 M6 Lock Washer Stainless Steel 50-pack

Product Description

The VALUE COLLECTION A210031 is a stainless steel external tooth lock washer designed for use with M6 fasteners. It features a 6.4mm inside diameter and an 11mm outside diameter, with a thickness of 0.7mm. Constructed from Grade 18-8 austenitic A2 stainless steel, this washer provides corrosion resistance and reliable holding power in a wide range of mechanical and structural fastening applications. The external tooth design bites into mating surfaces under torque load to resist loosening from vibration or thermal cycling. This washer is installed by electricians, HVAC technicians, plumbers, and general mechanical trades wherever M6 fasteners require a secure, vibration-resistant connection.

This external tooth lock washer is suited for residential and light commercial applications involving M6 screws and bolts. Common install scenarios include panel mounting, equipment enclosure assembly, conduit fittings, HVAC component brackets, and plumbing equipment mounting hardware. The stainless steel construction makes it appropriate for damp or corrosive environments where carbon steel hardware would be prone to rust. Sold in a package quantity of 50 pieces, it is well suited for technicians stocking a service van or completing a multi-point installation.

Key Features

• External tooth design grips mating surfaces to resist loosening under vibration
• Grade 18-8 austenitic A2 stainless steel construction for corrosion resistance
• 6.4mm inside diameter sized for M6 fasteners
• 11mm outside diameter with 0.7mm thickness for low-profile fitment
• Packaged in quantities of 50 for efficient jobsite or van stock use

Compatibility

Designed as a standard external tooth lock washer for use with M6 screws and bolts in mechanical, electrical, HVAC, plumbing, and general equipment assembly applications.

Installation Notes

This washer is installed by placing it between the fastener head and the mating surface before tightening the M6 screw. Ensure the mating surface is clean and free of debris so the teeth can seat properly. Follow applicable mechanical and electrical codes such as NEC for electrical enclosure hardware when selecting fastener hardware. Do not reuse a lock washer that has been fully compressed or deformed, as the locking effectiveness will be reduced.
