Value Collection SEW8XX0600-100BX M6 Lock Washer SS316

Product Description

The VALUE COLLECTION SEW8XX0600-100BX is a stainless steel external tooth lock washer designed for M6 fastener assemblies requiring reliable vibration resistance. With a 6.4mm inside diameter and 11.0mm outside diameter, this serrated washer seats tightly around an M6 screw shank and bites into mating surfaces to prevent loosening under dynamic loads. Manufactured from Grade 316 austenitic stainless steel to the A4 material classification, it offers strong corrosion resistance in wet, marine, and chemical environments. The uncoated finish is suitable for applications where coating compatibility or conductivity matters. This washer ships in a minimum order quantity of 100 units per package.

External tooth lock washers like the SEW8XX0600-100BX are commonly installed in HVAC equipment panels, electrical enclosures, plumbing fixture mounting, and pool equipment assemblies where stainless fasteners are specified. The external serration pattern increases holding force over plain washers and is well-suited for use with larger clearance holes where internal tooth designs would have insufficient grip area. Grade 316 stainless construction makes this washer appropriate for coastal installations, chemical exposure zones, and outdoor equipment subject to moisture and salt spray.

Compatibility

Designed as an OEM-style replacement or standard hardware component for M6 fastener assemblies across HVAC, electrical, plumbing, and pool equipment applications requiring stainless steel external tooth lock washers.

Installation Notes

Install using standard hand tools appropriate for the fastener being driven; no special tooling is required for washer placement. Ensure the serrated teeth face the surface being clamped, not the fastener head, for proper grip engagement. De-energize electrical panels and shut off system power or fluid supply before servicing any assembly where these washers are being installed or replaced. Grade 316 stainless hardware should be installed with compatible stainless fasteners to avoid galvanic corrosion at contact points.
