Value Collection R52001226 Square Head Bolt 1/2-13 Unc

Product Description

The VALUE COLLECTION R52001226 is a square head bolt designed for general fastening applications where a wrench-friendly head profile is required. Threaded to 1/2-13 UNC (Unified National Coarse) specifications, it features a 3-inch length under head and is manufactured from Grade 2 steel in an uncoated finish. Square head bolts are favored in mechanical, structural, and industrial assemblies where the head must be gripped by a pipe wrench or held in a square recess. Licensed tradespeople and maintenance professionals in HVAC, plumbing, and general construction regularly stock these fasteners for equipment mounting and structural connections.

This bolt is suited for light- to medium-duty fastening tasks in residential and commercial settings. The 1/2-13 UNC thread pitch is one of the most common coarse-thread standards, making this bolt compatible with standard UNC nuts and threaded hardware across a wide range of assemblies. It is used wherever a square head profile provides an advantage over hex head fasteners, including older equipment, pipe hangers, and fabricated steel assemblies.

Key Features

• 1/2-13 UNC thread standard for broad compatibility with standard coarse-thread hardware
• 3-inch length under head suits a variety of stack-up and clamping applications
• Grade 2 steel construction provides adequate tensile strength for general-purpose use
• Square head profile allows positive grip with a pipe wrench or square-drive tool
• Uncoated finish keeps the fastener ready for field painting, coating, or use as-is in dry indoor environments

Compatibility

Designed as a general-purpose UNC square head bolt for use with standard 1/2-13 UNC nuts and threaded hardware in mechanical, structural, and industrial fastening applications.

Installation Notes

Installation is typically performed by maintenance mechanics, pipefitters, HVAC technicians, or general tradespeople using standard wrenches or pipe wrenches. Always ensure the mating nut is also rated for Grade 2 or higher and matches the 1/2-13 UNC thread specification. Apply appropriate thread lubricant or anti-seize when required by the application or environment. Follow applicable structural and mechanical codes for torque and load requirements.
