Value Collection HCI20500350-025BX Hex Head Bolt 1/2-13

Product Description

The VALUE COLLECTION HCI20500350-025BX is a Grade 2 steel hex head bolt with a 1/2-13 UNC thread and a length under head of 3-1/2 inches. It is partially threaded and carries an uncoated, bright finish. Manufactured to ASTM A307 standards, this bolt is suited for general-purpose structural and mechanical fastening applications where high-strength alloy grades are not required. Installers in HVAC, plumbing, electrical, and general construction trades will find this bolt a dependable choice for equipment mounting, panel attachment, and bracket assembly work.

This bolt is used across a wide range of trade and light industrial applications, including HVAC unit mounting, electrical enclosure assembly, plumbing equipment installation, and general structural connections. The 1/2-13 UNC thread is one of the most common coarse-thread sizes in trade work, making this bolt compatible with standard hex nuts, lock nuts, and threaded inserts of the same thread specification. It is sold in multiples of 25, which suits job-site and shop inventory needs for ongoing fastener replenishment.

Compatibility

Designed as a general-purpose hex head bolt for use with 1/2-13 UNC threaded nuts, inserts, and tapped holes in steel, aluminum, and similar structural materials across trade and light industrial applications.

Installation Notes

Installation is performed by general tradespeople, maintenance technicians, and mechanics using a standard hex wrench or socket set. Ensure mating hardware such as nuts and washers match the 1/2-13 UNC thread specification before installation. Do not use this Grade 2 bolt in applications that specify Grade 5, Grade 8, or higher-strength fasteners, as the mechanical properties are not equivalent. Follow applicable codes and equipment manufacturer torque guidelines for the specific application.
