Value Collection R52001047 Square Head Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION R52001047 is a 1/4-20 UNC square head bolt manufactured from Grade 2 steel in an uncoated finish. The square head profile provides a larger bearing surface than a standard hex head, making it easier to drive with a wrench or hold in place against a mating surface. With a 1 inch length under head and a unified coarse thread form, this bolt is suited for general-purpose fastening in fabrication, structural assembly, and mechanical maintenance applications. Installation is straightforward for any trade professional working with threaded fastener assemblies.

This bolt is commonly used in light structural connections, equipment mounting, and general mechanical assemblies where a square head profile is required or specified. The 1/4-20 UNC thread is one of the most common coarse-thread sizes in North American trade applications, compatible with standard 1/4-20 nuts, inserts, and tapped holes. It is typically installed by millwrights, maintenance technicians, pipefitters, and general construction tradespeople. This SKU ships as a single piece but carries a minimum order quantity of 100 units, making it appropriate for bulk fastener restocking.

Key Features

• Square head profile provides increased torque surface and anti-rotation grip in slotted or recessed applications
• 1/4-20 UNC thread form matches the most widely used coarse-thread standard in North American fastener applications
• Grade 2 steel construction suitable for general-purpose, non-critical fastening applications
• Uncoated finish — no plating or coating that could affect thread tolerance or dimensional fit
• Manufactured to ANSI/ASME B18.2.1 dimensional standards for consistent head geometry and thread accuracy
• Minimum order quantity of 100 units supports bulk inventory and job-lot purchasing

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any application requiring a 1/4-20 UNC square head bolt conforming to ANSI/ASME B18.2.1 dimensional specifications.

Installation Notes

Installation requires a standard open-end or adjustable wrench sized for a 1/4-20 square head bolt. Ensure mating tapped holes or nuts conform to 1/4-20 UNC thread standards before installation to avoid cross-threading. Follow applicable torque guidelines from the equipment manufacturer or structural design specification for the fastened assembly. Do not substitute Grade 2 fasteners in applications that specify higher-grade hardware without engineering review.
