Value Collection R52001230 Square Head Bolt 1/2-13 Unc

Product Description

The VALUE COLLECTION R52001230 is a 1/2-13 UNC square head bolt designed for general fastening applications in structural, mechanical, and industrial assemblies. The bolt features a 4-inch length under head with a coarse UNC thread pattern on a 1/2-inch diameter shank. Manufactured from Grade 2 steel with an uncoated finish, it meets ANSI/ASME B18.2.1 dimensional standards. The square head profile allows for wrench or pipe-wrench engagement in tight spaces where a hex head tool may not seat properly. Installers in HVAC, plumbing, electrical, and general construction trades use square head bolts when tamper-resistance or legacy fitting compatibility is required.

This bolt is suited for residential and commercial applications involving structural framing, equipment mounting, utility connections, and mechanical assemblies where a 1/2-13 UNC coarse thread is specified. It is a solid choice for replacement fastening in older equipment that originally used square head hardware, or in any application where secure wrench engagement with a flat-sided head is preferred over a hex profile. Minimum order quantity is 25 pieces per order.

Key Features

• 1/2-13 UNC coarse thread for strong thread engagement in standard tapped holes
• 4-inch length under head accommodates thick stack-ups and structural connections
• Grade 2 steel construction provides adequate tensile strength for general-purpose fastening
• Uncoated finish — suitable for interior or dry-environment installations
• Square head profile allows pipe-wrench or adjustable-wrench drive where hex access is limited
• Conforms to ANSI/ASME B18.2.1 for dimensional consistency

Compatibility

Designed as a general-purpose 1/2-13 UNC square head bolt for use in structural, mechanical, and equipment-mounting applications requiring ANSI/ASME B18.2.1 compliant hardware.

Installation Notes

Square head bolts are typically installed by mechanical, structural, or maintenance trades using an adjustable wrench, pipe wrench, or square-head socket. Always ensure the mating nut or tapped hole matches the 1/2-13 UNC thread specification before installation. De-energize, depressurize, or de-load any assembly before replacing or installing fasteners. Do not exceed the load ratings for Grade 2 hardware in structural applications governed by applicable building or mechanical codes.
