Value Collection R52000113 Uss Flat Washer 3/8 in Steel

Product Description

The VALUE COLLECTION R52000113 is a USS flat washer designed for use with 3/8-inch screws and bolts. Manufactured from steel with a zinc-plated finish, it provides corrosion resistance in standard indoor and light-duty outdoor fastening applications. The washer measures 7/16 inches inner diameter, 1 inch outer diameter, and 0.0781 inches thick. USS-standard flat washers distribute load across the bearing surface, reducing fastener pull-through and protecting the base material. Plumbers, electricians, HVAC technicians, and general contractors commonly use these washers during equipment mounting, pipe support installation, and panel assembly work.

This washer suits a wide range of trade and industrial fastening tasks where a 3/8-inch fastener is used. Typical applications include equipment anchoring, structural connections, bracket mounting, and any assembly where load distribution under a nut or bolt head is required. The zinc plating makes it appropriate for use in dry to moderately humid environments. It is sold individually and is compatible with standard 3/8-inch threaded fasteners in inch-measurement systems.

Key Features

• USS flat washer standard — wider outer diameter than SAE, providing greater load distribution
• Steel construction for reliable strength in mechanical and structural fastening
• Zinc-plated finish for corrosion resistance in standard service environments
• 7/16 inches inner diameter fits 3/8-inch screws and bolts with proper clearance
• 1 inch outer diameter and 0.0781 inches thickness meet USS dimensional standards
• Inch measurement system — compatible with standard US fastener hardware

Compatibility

Designed for use with 3/8-inch screw and bolt fasteners in inch-measurement applications. Fits standard 3/8-inch threaded hardware as an OEM-style or replacement flat washer in mechanical, electrical, HVAC, and plumbing assembly contexts.

Installation Notes

Install with the washer seated flat against the base material surface before seating the nut or bolt head. Ensure the fastener shank passes freely through the 7/16-inch inner diameter without binding. Follow applicable codes such as NEC or IFGC when using fasteners in electrical panel or gas equipment mounting applications. Inspect the zinc coating for damage before installation in environments with exposure to moisture.
