Value Collection LW7XX00500-100BX M5 Split Lock Washer 316 Ss

Product Description

The VALUE COLLECTION LW7XX00500-100BX is a metric split lock washer engineered for M5 fastener applications requiring corrosion-resistant hardware. Manufactured from 316 austenitic stainless steel to Grade A4 classification, this washer delivers strong resistance to chloride environments, making it suitable for marine, chemical, and outdoor installations. The inside diameter ranges from 5.1 to 5.4mm, with a maximum outside diameter of 9.2mm and a thickness of 1.2mm. The bright, uncoated finish preserves the natural surface of the 316 alloy. Conforms to DIN 127B standards for metric split lock washers. Sold in a minimum order quantity of 100 pieces.

This split lock washer is intended for use with M5 metric screws and bolts in assemblies where vibration loosening is a concern. Typical applications include mechanical equipment, electrical enclosures, marine hardware, food processing equipment, and other environments where stainless steel fastener hardware is specified. The Grade A4 designation confirms suitability for wet, corrosive, and outdoor service conditions. Installers working in marine or coastal environments commonly specify 316 stainless over 304 for its higher molybdenum content and improved pitting resistance.

Installation Notes

Split lock washers are placed between the fastener head or nut and the mating surface before torquing. Ensure the washer seats flat before driving the fastener to avoid uneven load distribution. Do not mix stainless steel washers with carbon steel fasteners in corrosive environments, as galvanic compatibility should be verified. Installation is typically performed by millwrights, electricians, plumbers, or marine technicians depending on the application.
