Hillman Fasteners 290015 Fender Washer 1/4x1-1/4 in 100pk

Product Description

The HILLMAN FASTENERS 290015 is a zinc plated steel fender washer sold in a 100-piece pack. Fender washers feature an oversized outer diameter relative to the center hole, distributing load across a wider surface area to reduce pull-through on thin or soft materials. The 1/4-inch inner diameter fits standard 1/4-inch fasteners, and the 1-1/4-inch outer diameter provides broad bearing surface. The zinc plating offers corrosion resistance suitable for general indoor and light outdoor use. Plumbers, electricians, HVAC technicians, and general contractors keep these on hand for panel work, conduit mounting, duct hanging, and structural fastening applications.

These fender washers are used across residential and commercial trade work wherever a standard flat washer provides insufficient bearing surface. Common applications include securing sheet metal screws in thin-gauge steel, anchoring conduit straps, supporting pipe hangers, and distributing load on wood framing or drywall assemblies. The 100-piece pack quantity suits field service kits, job-site bins, and maintenance supply stock.

Key Features

• 1/4-inch inner diameter fits standard 1/4-inch fasteners
• 1-1/4-inch outer diameter distributes load across a wider bearing surface
• Zinc plated steel construction for corrosion resistance in general service environments
• Oversized OD-to-ID ratio typical of fender washer design reduces fastener pull-through

Compatibility

Designed for use with standard 1/4-inch bolts, screws, and threaded rod in general construction, mechanical, and trade installation applications.

Installation Notes

Install with standard wrenches or nut drivers appropriate to the mating fastener. Ensure the washer seats flush against the work surface before torquing the fastener. For outdoor or high-moisture environments, verify that zinc plating provides adequate corrosion protection for the application or select a more protective finish. No special tools or trade licensing are required for washer installation.
