Value Collection HCI20250550-050BX Hex Head Bolt 1/4-20

Product Description

The VALUE COLLECTION HCI20250550-050BX is a 1/4-20 UNC hex head bolt with a 5-1/2 inch length under head. Made from Grade 2 uncoated steel and manufactured to ASTM A307 standards, it features partial threading along the shank. This is a general-purpose fastener suited for structural and mechanical assembly work where a standard-strength, uncoated steel bolt is specified. Maintenance technicians, millwrights, and general contractors commonly install this type of bolt in light to moderate load applications. The bright uncoated finish makes it a cost-effective choice when corrosion protection is not required by the application or specification.

This bolt is appropriate for use in indoor or sheltered mechanical assemblies, equipment mounting, framing connections, and general fabrication tasks. The 1/4-20 UNC thread size and 5-1/2 inch body length make it a common specification in both production-line assembly and field repair contexts. The ASTM A307 Grade A designation covers carbon steel bolts in this size range, making the fastener appropriate for structural applications that do not require high-strength hardware such as SAE Grade 5 or Grade 8. This product ships in a minimum order quantity of 50 pieces.

Key Features

• 1/4-20 UNC thread size with 5-1/2 inch length under head
• Partially threaded shank allows for clamping without thread engagement through the full grip length
• Grade 2 steel construction meets ASTM A307 fastener standards
• Bright uncoated finish — no coating to interfere with thread gauging or torque values
• Inch measurement system; hex head drive for standard wrench or socket installation

Compatibility

Designed as a standard 1/4-20 UNC hex head bolt for general mechanical and structural assembly applications where ASTM A307 Grade 2 uncoated steel fasteners are specified.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized to the 1/4-20 hex head. Always confirm the mating thread specification and grip length requirements before installation. De-energize and lock out equipment before fastening in electrical or mechanical enclosures. Do not use this Grade 2 fastener as a substitute in applications requiring Grade 5, Grade 8, or metric high-strength hardware.
