Value Collection HCI20250300-050BX Hex Head Bolt 1/4-20

Product Description

The VALUE COLLECTION HCI20250300-050BX is a 1/4-20 UNC hex head bolt designed for general-purpose fastening in structural, mechanical, and equipment assembly applications. Manufactured from Grade 2 steel with a bright uncoated finish, this bolt measures 3 inches under the head and features partial threading along the shank. It conforms to ASTM A307 standards, making it suitable for low-carbon steel bolting in a wide range of light-duty load applications. Tradespeople and contractors working across plumbing, HVAC, electrical, and general construction will find this fastener useful for securing brackets, supports, equipment panels, and structural connections.

This bolt is appropriate for residential and light commercial applications where ASTM A307 Grade 2 compliance is required. The partial threading provides a smooth shank section that helps maintain alignment in clearance holes and prevents thread engagement where grip length is critical. Typical install scenarios include equipment mounting, uni-strut connections, panel attachment, and structural support brackets. This SKU is sold as a minimum order quantity of 50 units per order, with individual package quantity of 1.

Compatibility

Designed as a standard inch-series hex head fastener compatible with 1/4-20 UNC nuts, washers, and tapped connections conforming to ASTM A307 specifications in general mechanical and structural assembly applications.

Installation Notes

Installation is performed by mechanical contractors, maintenance technicians, or tradespeople using standard hand tools or power drivers with the appropriate hex socket or wrench. Ensure mating nuts or tapped holes are also rated for Grade 2 or equivalent loads before final torque. Avoid use in high-stress or impact-loaded joints where higher-grade fasteners are specified. For exterior or corrosive environments, a coated or plated variant should be selected instead of this uncoated version.
