Hillman Fasteners 280054 Sae Flat Washer No. 10 100 Pack

Product Description

The HILLMAN FASTENERS 280054 is a No. 10 SAE flat washer sold in a 100-piece pack. Zinc plated steel construction distributes fastener load across a bearing surface, reducing pull-through and protecting the mating material from damage under the fastener head or nut. SAE flat washers follow standard outside diameter and thickness tolerances, making them a direct fit for general mechanical assembly, HVAC equipment mounting, electrical panel work, and plumbing fixture installations. Plumbers, electricians, HVAC technicians, and maintenance professionals keep these on hand for everyday service calls.

These washers are suited for residential and light commercial applications where a No. 10 fastener is used. Typical uses include securing equipment brackets, mounting electrical junction boxes, anchoring duct hangers, and general hardware assembly on service trucks and job sites. The 100-piece pack format keeps supply readily available for high-volume fastening tasks without frequent restocking.
