Value Collection HCI20310050-100BX Hex Bolt 5/16-18 1/2in Grade 2

Product Description

The VALUE COLLECTION HCI20310050-100BX is a fully threaded hex head bolt in 5/16-18 UNC thread, with a 1/2-inch length under head. Manufactured from Grade 2 steel with a bright uncoated finish, it meets ASTM A307 standards for general-purpose fastener applications. The fully threaded shank allows engagement along the entire bolt length, making it well suited for through-bolting thin materials where maximum thread contact is needed. This bolt ships in a minimum order quantity of 100 pieces and is intended for use by contractors, maintenance technicians, and trade professionals who require a reliable, code-referenced fastener.

This hex head bolt is used across a wide range of light-duty to medium-duty structural and mechanical assembly applications. Common installations include HVAC equipment mounting, electrical panel and enclosure assembly, plumbing fixture brackets, and general construction framing connections. The 5/16-18 UNC thread pattern is a standard inch-series size widely encountered in residential and light commercial equipment. Grade 2 steel is appropriate for low-to-moderate tensile load applications where high-strength alloy fasteners are not required by code or design spec.

Key Features

• 5/16-18 UNC thread for broad compatibility with standard inch-series hardware
• 1/2-inch length under head suits thin-material through-bolting and close-clearance fastening
• Fully threaded shank maximizes thread engagement across the full bolt length
• Grade 2 steel construction meets ASTM A307 general-purpose fastener standard
• Bright uncoated finish — inspect and coat as needed for corrosive or outdoor environments
• Sold in boxes of 100 for job-site and shop stock quantities

Compatibility

Designed as a general-purpose inch-series hex head bolt compatible with any standard 5/16-18 UNC threaded hole or nut in steel, wood, or composite assemblies where ASTM A307 Grade 2 fasteners are specified or acceptable.

Installation Notes

Installation is performed with a standard 1/2-inch hex wrench or socket. Confirm that the mating nut or tapped hole is also 5/16-18 UNC before driving. Grade 2 uncoated steel is not rated for direct outdoor or high-moisture exposure without additional corrosion protection — apply thread-locking compound or anti-seize as required by the application. Follow applicable codes such as AISC, IBC, or equipment manufacturer torque specifications; no specific torque value is implied by this listing.
