Hillman Fasteners 270033 1 Inch Flat Washer Zinc Plated 5 Lb

Product Description

The HILLMAN FASTENERS 270033 is a 5-pound pack of 1-inch zinc-plated steel flat washers in a wide-pattern USS configuration. Each pack contains approximately 27 pieces. These washers distribute load across a larger bearing surface, reducing fastener pull-through and protecting the material beneath the fastener head or nut. The zinc plating provides corrosion resistance for general indoor and light outdoor applications. Installers in plumbing, electrical, HVAC, and general construction trades reach for USS wide-pattern flat washers when working with coarser-tolerance fastener assemblies that require extra bearing area.

These washers are suited for residential and light commercial construction and maintenance applications. Typical use cases include anchoring equipment, mounting brackets, securing pipe hangers, and assembling structural connections where a standard flat washer does not provide sufficient bearing surface. The wide USS pattern is designed to pair with coarse-thread fasteners. Sold in a 5-pound bulk pack, this format works well for contractors and service techs who go through hardware in volume and want to minimize restocking frequency.

Key Features

• Wide-pattern USS flat washer — larger outer diameter for increased load distribution
• Zinc-plated steel construction for corrosion resistance in general service environments
• 1-inch nominal size to match standard 1-inch fastener assemblies
• Bulk 5-pound pack with approximately 27 pieces per pack
• Suitable for pairing with coarse-thread bolts and nuts in USS-specification assemblies

Compatibility

Designed as a wide-pattern USS flat washer for use with 1-inch coarse-thread fasteners in standard residential and commercial fastener assemblies.

Installation Notes

Installation of flat washers requires no special tools beyond the wrench or socket used to tighten the fastener assembly. Always place the washer between the fastener head or nut and the mating surface before torquing. Inspect washers for deformation or corrosion before reuse in structural applications. Follow applicable building codes and fastener manufacturer torque guidelines for the specific assembly.
