Value Collection SEW8X0600-100BX M6 Lock Washer Ss 18-8

Product Description

The VALUE COLLECTION SEW8X0600-100BX is a stainless steel external tooth lock washer sized for M6 fasteners. It features a serrated external tooth profile that bites into the mating surface and fastener bearing face to resist loosening under vibration and dynamic loads. The washer is manufactured from Grade 18-8 austenitic stainless steel, also designated A2, providing corrosion resistance suitable for wet, outdoor, and chemically exposed environments. The inside diameter measures 6.4mm, outside diameter measures 11.0mm, and thickness measures 0.7mm. This package contains 100 washers per order quantity. Electricians, plumbers, HVAC technicians, and mechanical contractors use this style of lock washer in panel assemblies, enclosure mounting, and equipment installations requiring secure, corrosion-resistant fastening.

External tooth lock washers in this size range are commonly used in light-gauge sheet metal assemblies, electrical enclosures, junction boxes, equipment frames, and control panel builds. The M6 sizing is standard across a wide range of imported and domestic HVAC equipment, electrical gear, and plumbing support hardware. The stainless steel construction makes these washers appropriate for coastal environments, chemical exposure areas, food service equipment, and other applications where carbon steel hardware would corrode.

Compatibility

Designed for use with M6 screws and bolts across general mechanical, electrical, and HVAC assembly applications requiring an external tooth lock washer with a 6.4mm inside diameter.

Installation Notes

Install with the teeth facing the fastener bearing surface or the workpiece surface, not between two hardened washers where the teeth cannot engage. Torque the fastener to the value specified by the equipment manufacturer or applicable fastener standard. Always de-energize and lock out electrical equipment before performing any fastener work inside panels or enclosures. Stainless steel fastener components can gall under high torque; apply an appropriate anti-seize compound when the application allows.
