Value Collection A410445 M8 Split Lock Washer 316 Ss 50pk

Product Description

The VALUE COLLECTION A410445 is a metric split lock washer designed for use with M8 fasteners. Manufactured from 316 austenitic stainless steel (Grade A4), it delivers reliable corrosion resistance in wet, marine, and chemical-exposure environments. The washer has a minimum inside diameter of 8.1 inches converted — 8.1 mm — and a maximum outside diameter of 14.8 mm, with a uniform thickness of 2 mm. The uncoated finish maintains the natural properties of the stainless alloy. This washer functions by biting into the bearing surface and fastener head to resist rotational loosening under vibration and dynamic loads. It ships in a package quantity of 50 pieces per order unit.

Split lock washers of this type are used across plumbing, mechanical, and equipment-mounting applications where fastener security under vibration is required. The M8 sizing and metric DIN 127B standard make this washer compatible with metric bolt patterns commonly found in HVAC equipment panels, pump assemblies, and structural brackets in both residential and light commercial installations. Plumbers, HVAC technicians, and maintenance professionals routinely stock this size for field repairs and equipment tie-down work. The 316 stainless steel construction makes it a preferred choice in corrosive or outdoor environments over standard carbon steel alternatives.

Compatibility

Designed for use with M8 metric screws and bolts conforming to standard metric thread specifications. Suitable for DIN 127B split lock washer applications in metric fastener assemblies.

Installation Notes

Installation should be performed by a qualified technician familiar with metric fastener assemblies. De-energize or depressurize the equipment before servicing any fastened joints. Place the split lock washer between the fastener head and the bearing surface, ensuring the split gap is properly oriented before torquing. Do not reuse lock washers that have been fully compressed flat, as the locking function will be diminished.
