Hillman Fasteners 270030 7/8 Inch Flat Washer Zinc Plated 5 Lb

Product Description

The HILLMAN FASTENERS 270030 is a 7/8 inch zinc plated steel flat washer sold in a 5 lb pack containing approximately 33 pieces. This wide pattern USS flat washer distributes load across a broader surface area than standard flat washers, reducing the risk of fastener pull-through in softer materials. The zinc plating provides corrosion resistance suitable for general indoor and light outdoor applications. Electricians, plumbers, HVAC installers, and general contractors use flat washers like these in mechanical and structural assemblies where even load distribution under bolt heads and nuts is required.

This washer is suited for use in residential and light commercial construction, mechanical assemblies, equipment mounting, and utility installations. The USS wide pattern designation indicates an outside diameter larger than SAE standard, making it appropriate for applications involving oversized holes or soft base materials where bearing surface area matters. The 5 lb bulk pack format is practical for job-site use or shop stock replenishment.

Key Features

• 7/8 inch nominal size, USS wide pattern for increased bearing surface
• Zinc plated steel construction for corrosion resistance in general service environments
• Bulk 5 lb pack with approximately 33 pieces per pack
• Wide pattern outside diameter exceeds SAE standard for better load distribution over oversized holes
• Package quantity of 12 packs per case for stocking and resale

Compatibility

Designed for use with 7/8 inch fastener hardware in general mechanical, structural, and utility assembly applications where a USS wide pattern flat washer is specified.

Installation Notes

Flat washers are installed by placing them between the fastener head or nut and the work surface before tightening. Ensure the correct nominal size matches the bolt or screw diameter being used. Follow applicable building or mechanical codes for fastener assembly torque and material requirements. No special tools are required beyond a wrench or socket appropriate to the mating fastener.
