Value Collection A410444 M6 Split Lock Washer 316 Ss 50pk

Product Description

The VALUE COLLECTION A410444 is a metric split lock washer designed for use with M6 fasteners in corrosion-resistant applications. Manufactured from 316 austenitic stainless steel, Grade A4, this washer meets DIN 127B standards and delivers reliable locking action under vibration and dynamic load conditions. The split design bites into mating surfaces to resist loosening, making it well suited for marine, chemical, and outdoor environments where standard carbon steel hardware would be vulnerable to corrosion. Sold in a package of 50 uncoated washers, this SKU is appropriate for maintenance stock, small fabrication jobs, and field service kits. Inside diameter runs 6.1 to 6.5mm with a maximum outside diameter of 11.8mm and a thickness of 1.6mm.

This washer is used wherever M6 threaded fasteners require a locking element in corrosive or wet service environments. Typical applications include marine deck hardware, pool and waterpark equipment, chemical processing enclosures, food-service fabrication, and coastal HVAC or electrical installations where 304 stainless or zinc-plated hardware is not sufficient. The uncoated finish is compatible with 316 stainless bolts, screws, and nuts and requires no additional prep before installation.

Key Features

• 316 austenitic stainless steel, Grade A4 — excellent resistance to chlorides and salt spray
• DIN 127B standard split lock washer geometry for consistent locking performance
• Inside diameter 6.1 to 6.5mm accommodates standard M6 fastener shank tolerances
• Maximum outside diameter 11.8mm, thickness 1.6mm — compact profile for tight assemblies
• Uncoated finish — no coating delamination risk in immersed or chemically active environments
• Package of 50 pieces — suitable for stocking or multi-fastener job lots

Compatibility

Designed for use with M6 threaded fasteners in metric assemblies conforming to DIN standards. Fits screws, bolts, and nuts with a shank diameter compatible with a 6.1 to 6.5mm inside diameter washer bore.

Installation Notes

Install between the fastener head or nut and the mating surface with the split ends oriented to bite into both contact faces as the fastener is torqued. Ensure mating fasteners are also 316 or Grade A4 stainless steel to prevent galvanic corrosion in wet service conditions. Do not reuse split lock washers that have been fully compressed flat, as the locking function is diminished. Follow applicable mechanical or structural codes for fastener torque requirements on the specific assembly.
