Value Collection R52001112 Square Head Bolt 5/16 Unc

Product Description

The VALUE COLLECTION R52001112 is a square head bolt designed for general fastening applications in mechanical, structural, and industrial assemblies. It features a 5/16-18 UNC thread size and a 3/4 inch length under head, making it suitable for medium-duty clamping and bolted joint applications. Manufactured from Grade 2 steel with an uncoated finish, this bolt meets ANSI/ASME B18.2.1 dimensional standards. The square head profile allows engagement with a wrench or socket in tight spaces where a conventional hex head may not seat properly. Licensed tradespeople and industrial maintenance technicians are the typical installers of this fastener type.

This square head bolt is used in residential and commercial mechanical installations, fabrication work, agricultural equipment, and general maintenance applications. The 5/16-18 UNC thread is a coarse-thread designation, which is well suited to steel-to-steel and steel-to-wood assemblies where fast engagement and vibration resistance are priorities. It is a single-piece fastener sold individually per package, with a minimum order quantity of 100 pieces per order.

Key Features

• Meets ANSI/ASME B18.2.1 dimensional standards for consistent fitment
• Square head profile allows wrench engagement in confined or recessed spaces

Compatibility

Designed as an OEM-style replacement or standard-specification fastener compatible with any application requiring a 5/16-18 UNC square head bolt conforming to ANSI/ASME B18.2.1 dimensional standards.

Installation Notes

Installation is performed by machinists, maintenance technicians, fabricators, or general tradespeople using standard open-end, box-end, or socket wrenches sized for a square head profile. Always ensure mating threads are clean and free of debris before installation. Do not over-torque Grade 2 fasteners, as they have lower proof load ratings than Grade 5 or Grade 8 hardware. Follow applicable ANSI or project-specific torque specifications for the joint design being assembled.
