Hillman 6447 Steel Flat Sae Washer Size 8 30 Pack

Product Description

The HILLMAN 6447 is a zinc-plated steel flat SAE washer sized for use with No. 8 bolts and screws. Flat washers distribute the load of a fastener across a wider surface area, reducing the risk of the fastener head or nut pulling through or damaging the material beneath. The zinc plating provides a corrosion-resistant finish suited for general indoor and light-duty applications. Each pack contains 30 washers. This type of hardware is installed by contractors, plumbers, electricians, HVAC technicians, and general tradespeople as a standard component in mechanical and structural assemblies.

These washers are appropriate for residential and light commercial fastening applications where a No. 8 bolt or screw is used. Common uses include wood framing connections, equipment mounting, fixture installation, and panel assembly. The SAE sizing standard indicates a smaller outer diameter relative to USS-standard washers of the same nominal size, making them well suited for tight clearance applications or where a more finished appearance is needed.

Key Features

• Zinc-plated finish for corrosion resistance in general-use environments
• Flat SAE profile distributes fastener load to protect mating surfaces
• Sized for No. 8 bolts and screws
• Steel construction for reliable strength in standard fastening applications
• Pack of 30 for job-site and service-call quantities

Compatibility

Designed for use with No. 8 bolts or screws in standard SAE fastening applications across residential and light commercial assemblies.

Installation Notes

Install flat washers between the fastener head or nut and the mating surface before tightening. No special tools are required beyond those used for the primary fastener. Ensure the washer inner diameter is compatible with the fastener shank before assembly. For outdoor or high-moisture environments, consider a higher-grade corrosion-resistant fastener system alongside these washers.
