Hillman Fasteners 830556 Flat Washer No. 10 Ss 100 Pack

Product Description

The HILLMAN FASTENERS 830556 is a No. 10 stainless steel commercial flat washer sold in a 100-piece pack. Flat washers distribute fastener load across a surface, reducing the risk of pull-through and protecting the material beneath the bolt head or nut. This washer is manufactured to commercial-grade dimensional standards and constructed from stainless steel for corrosion resistance in demanding environments. The 100-pack format suits contractors, service technicians, and maintenance crews who need a reliable quantity on hand for recurring fastener work across HVAC, plumbing, electrical, and general mechanical applications.

Commercial flat washers in No. 10 sizing see frequent use in light-gauge metal assembly, equipment mounting, panel attachment, and general mechanical fastening tasks. The stainless steel construction makes these washers suitable for installations where moisture, humidity, or chemical exposure is a factor, including rooftop HVAC equipment, outdoor electrical enclosures, and wet-area plumbing brackets. Packaged in a box of 100, this SKU is appropriate for both job-site stock and shop inventory replenishment.
