Hillman Fasteners 6447 Flat Washer No. 8 Zinc Plated 30 Pack

Product Description

The HILLMAN FASTENERS 6447 is a No. 8 zinc plated steel flat washer sold in a 30-piece pack. Flat washers distribute load across a fastened joint, reducing the risk of surface damage and fastener pull-through. The zinc plating provides a basic corrosion barrier suitable for general indoor and light-duty outdoor applications. These are a standard consumable stocked by plumbers, electricians, HVAC techs, and general contractors for everyday fastening work across wood, metal, and composite substrates.

This washer is sized for No. 8 fasteners and fits into a wide range of residential and light commercial assembly tasks. Common applications include equipment panel mounting, conduit support hardware, cabinet and enclosure assembly, and general mechanical fastening where a load-spreading washer is required under a bolt head or nut. The 30-piece pack format is suited for service vans, job boxes, and shop inventory.

Installation Notes

Place the flat washer between the fastener head or nut and the mating surface before tightening. Ensure the washer is seated flat and centered on the fastener shank. For electrical enclosure or panel work, follow NEC guidelines for hardware used in electrical assemblies. Always confirm the washer material and plating are appropriate for the exposure conditions of the installation.
