Value Collection LW7XX03000-010BX M30 Split Lock Washer

Product Description

The VALUE COLLECTION LW7XX03000-010BX is a metric split lock washer designed for M30 fastener assemblies requiring corrosion-resistant hardware. Manufactured from 316 austenitic stainless steel to Grade A4 specification, this washer provides reliable spring tension under bolt heads and nuts to resist loosening caused by vibration and thermal cycling. The bright uncoated finish maintains dimensional accuracy and is suitable for wet, marine, and chemically aggressive environments where standard carbon steel hardware would corrode prematurely. Minimum order quantity is 10 pieces per order.

This washer is used in structural, mechanical, and industrial fastener assemblies where M30 metric hardware is specified. Typical applications include marine equipment, chemical processing machinery, food service fabrication, and outdoor structural connections. The DIN 127B standard governs the dimensional and mechanical requirements, making this washer a direct fit wherever that standard is called out on engineering drawings or maintenance specs. Installation is performed by maintenance technicians, millwrights, pipefitters, and structural tradespeople working with metric fastener systems.

Key Features

• 316 austenitic stainless steel construction for superior corrosion resistance in marine and chemical environments
• Grade A4 material designation per metric fastener standards
• Conforms to DIN 127B dimensional standard for metric split lock washers
• Bright uncoated finish with no plating or coating to degrade dimensional tolerances
• Inside diameter range of 30.5 to 31.7 mm accommodates standard M30 bolt shank clearance
• 6 mm thickness delivers adequate spring force for M30 fastener assemblies

Compatibility

Designed for use with M30 metric fasteners conforming to standard metric thread specifications. Fits assemblies calling out DIN 127B split lock washers in 316 stainless steel or Grade A4 stainless steel.

Installation Notes

Installation is performed by qualified tradespeople following applicable fastener assembly procedures. Ensure mating surfaces are clean and free of debris before seating the washer. The split lock washer should be placed between the nut or bolt head and the clamping surface, oriented so the split ends bite into both surfaces as the fastener is torqued. Do not reuse lock washers that have been fully flattened, as they will no longer provide adequate spring tension.
