The VALUE COLLECTION R52000935 is a square head bolt designed for general-purpose fastening in structural, mechanical, and industrial applications. It features a 1-8 UNC thread size and a 6-inch length under head, making it suitable for applications that require a longer grip length or deeper thread engagement. The square head design allows for positive wrench engagement, reducing the chance of slippage during installation or removal. Manufactured from Grade 2 steel with an uncoated finish, this bolt meets ANSI/ASME B18.2.1 standards and weighs approximately 1.51 pounds.
This bolt is used in a wide range of trade and industrial settings, including equipment assembly, structural framing, and heavy-duty mechanical installations. The coarse UNC thread pattern provides fast assembly and works well in applications where vibration resistance and high clamping load are secondary to installation speed and ease of use. It is commonly installed by millwrights, ironworkers, pipefitters, and general maintenance technicians working on steel fabrication or equipment mounting tasks.
Designed as a general-purpose replacement or new-installation fastener for applications requiring a 1-8 UNC coarse thread square head bolt conforming to ANSI/ASME B18.2.1.
Installation should be performed by a qualified tradesperson using an appropriately sized open-end or adjustable wrench rated for the fastener size. Always verify that mating threads and hole clearances conform to ANSI/ASME B18.2.1 tolerances before installation. Apply thread lubricant or anti-seize compound if required by the application to prevent galling on uncoated steel threads. Confirm torque requirements based on joint design specifications before final tightening.
