Value Collection HCI20310087-100BX Hex Head Bolt 5/16-18

Product Description

The VALUE COLLECTION HCI20310087-100BX is a fully threaded hex head bolt designed for general-purpose fastening in structural and mechanical assemblies. Manufactured from Grade 2 steel with a bright uncoated finish, this bolt features a 5/16-18 UNC thread and measures 7/8 inches in length under the head. It meets ASTM A307 standards, making it appropriate for low-carbon steel fastening applications. This box quantity of 100 bolts is suited for contractors, maintenance technicians, and trade professionals who need a reliable supply of standard hex fasteners on hand.

This bolt is used across residential and commercial construction, mechanical equipment installation, plumbing and HVAC equipment mounting, and general fabrication work. The 5/16-18 UNC thread is one of the most common inch-series thread sizes in trade applications, fitting standard nuts, flanges, and tapped holes found in a wide range of equipment and structural components. Fully threaded along the entire shank, it provides maximum thread engagement for thinner material applications.

Installation Notes

Installation should be performed by qualified tradespeople using a standard hex wrench or socket set sized for a 5/16 inch hex head bolt. Always ensure mating threads are clean and free of debris before fastening. Do not use in applications requiring higher-grade fasteners — verify that Grade 2 and ASTM A307 ratings meet the load and shear requirements of the specific application before use. Consult applicable building or mechanical codes for torque and clamping requirements.
