Value Collection SEW7X0600-100BX M6 Lock Washer Ss 100pk

Product Description

The VALUE COLLECTION SEW7X0600-100BX is an external tooth lock washer designed for use with M6 fasteners. It features a 6.4mm inside diameter and an 11.0mm outside diameter, with a thickness of 0.7mm. Constructed from 18-8 austenitic stainless steel, Grade A2, this washer delivers solid corrosion resistance in damp, outdoor, and chemically exposed environments. The external tooth design bites into both the fastener bearing surface and the substrate to resist loosening under vibration and dynamic loads. This washer ships in a minimum quantity of 100 units per order and is sold as a single package of 100.

External tooth lock washers in this size and material are widely used in mechanical, electrical, HVAC, plumbing, and general trade applications wherever M6 threaded fasteners require additional locking force. Grade A2 stainless steel makes these washers suitable for use in marine-adjacent, food-service-adjacent, or corrosion-prone environments where carbon steel hardware would be inappropriate. They are commonly installed by maintenance technicians, millwrights, electricians, and HVAC service professionals working on panel assemblies, equipment mounting, and structural connections.

Key Features

• External tooth design grips both fastener and mating surface to resist vibration-induced loosening
• 18-8 austenitic stainless steel, Grade A2 for strong corrosion resistance
• 6.4mm inside diameter sized for M6 screws and bolts
• 11.0mm outside diameter with 0.7mm thickness for a low-profile, consistent bearing surface
• Uncoated finish — no plating to flake, chip, or contaminate the joint
• Sold in a 100-unit package to support production, maintenance, and service work

Compatibility

Designed for use with M6 threaded fasteners. Suitable as a standard external tooth lock washer in any application requiring a 6.4mm inside diameter and 11.0mm outside diameter washer in stainless steel construction.

Installation Notes

Install with the teeth facing the fastener head or nut, not the substrate, unless application requirements specify otherwise. Ensure the mating surface is clean and free of debris before seating the washer to allow the teeth to engage properly. Power down or de-energize any electrical panel or equipment before installing fasteners in live assemblies. Do not reuse lock washers that have been fully compressed or deformed, as the locking effectiveness is reduced after initial torque-down.
