Value Collection LW7XX01800-050BX M18 Split Lock Washer 316 Ss

Product Description

The VALUE COLLECTION LW7XX01800-050BX is an M18 metric split lock washer manufactured from 316 austenitic stainless steel to Grade A4 specification. It is designed to resist loosening under vibration and dynamic loads in bolted assemblies where corrosion resistance is critical. The washer features a bright, uncoated finish and meets DIN 127B and DIN 7980 standards. With an inside diameter of 18.2 mm, a maximum outside diameter of 29.4 mm, and a thickness of 3.5 mm, this washer fits M18 fastener applications across marine, chemical processing, and general industrial environments. Installation is performed by mechanics, millwrights, and maintenance technicians working with metric fastener systems.

This split lock washer is suited for use in corrosive or wet environments where standard carbon steel hardware would be prone to rust or galvanic degradation. Typical applications include marine deck hardware, food processing equipment, chemical plant piping flanges, and outdoor structural assemblies. The 316 alloy provides superior chloride resistance compared to 304 stainless, making it the preferred choice when saltwater or chemical exposure is expected. This item is sold in a minimum order quantity of 5 pieces, packaged as a single unit per the standard packaging configuration.

Key Features

• 316 austenitic stainless steel construction meets Grade A4 corrosion resistance requirements
• Conforms to DIN 127B and DIN 7980 fastener standards for metric split lock washers
• Bright, uncoated finish — no coating to chip, flake, or interfere with electrical continuity
• Inside diameter range of 18.2 to 19 mm accommodates standard M18 bolt shanks
• 3.5 mm washer thickness provides reliable spring tension to resist fastener back-off under vibration
• Minimum order quantity of 5 supports job-lot purchasing for service and maintenance applications

Compatibility

Designed for use with M18 metric fasteners in assemblies governed by DIN 127B and DIN 7980 standards. Suitable as a direct replacement or supplemental washer in any metric bolted joint requiring an M18 split lock washer in 316 stainless steel.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using standard metric hand tools. Power down or de-energize any equipment and relieve system pressure before disassembling bolted joints. Place the split lock washer between the nut or bolt head and the mating surface, with the split gap allowing the washer to bite into both surfaces as the fastener is torqued. Follow applicable industry torque guidelines for M18 fasteners in stainless steel assemblies, noting that stainless fasteners are susceptible to galling — apply an appropriate anti-seize compound where recommended by the equipment manufacturer.
