Value Collection HCI20250275-050BX Hex Head Bolt 1/4-20

Product Description

The VALUE COLLECTION HCI20250275-050BX is a 1/4-20 UNC hex head bolt designed for general fastening applications across mechanical, structural, and trade assembly work. The bolt measures 2.75 inches in length under the head and is partially threaded, making it suited for through-bolting applications where the unthreaded shank provides a bearing surface. Manufactured from steel to Grade 2 specifications and left uncoated bright finish, this bolt meets ASTM A307 standards for low-carbon steel fasteners. It is sold in a minimum order quantity of 50 pieces per box, making it appropriate for stocking or job-lot purchasing.

This hex head bolt is used across a wide range of residential and commercial installation scenarios including HVAC equipment mounting, plumbing bracket fastening, electrical enclosure assembly, and general mechanical work. The 1/4-20 thread size is one of the most common inch-series fastener sizes in trade work, fitting standard hex nuts, lock nuts, and tapped holes encountered on equipment frames, strut channel, and field-fabricated brackets. Partially threaded shanks are preferred when clamping force needs to be applied without thread engagement along the full grip length.

Compatibility

Designed as a standard inch-series hex head bolt compatible with 1/4-20 UNC nuts, washers, and tapped components used in general mechanical and trade assembly applications.

Installation Notes

Installation is appropriate for any trade working with standard inch-series fasteners, including HVAC technicians, plumbers, and electricians securing equipment, brackets, or enclosures. Always de-energize equipment and relieve system pressure before fastening or re-fastening components on live systems. Use the correct hex drive socket or wrench to avoid rounding the head. Uncoated fasteners are not recommended for outdoor or high-humidity environments without additional corrosion protection.
