Value Collection HCI20250375-050BX Hex Head Bolt 1/4-20

Product Description

The VALUE COLLECTION HCI20250375-050BX is a 1/4-20 UNC hex head bolt intended for general fastening applications across mechanical, HVAC, plumbing, and electrical installations. The bolt measures 3-3/4 inches in length under the head and features partial threading, making it well suited for through-bolting into clamped assemblies where a smooth shank is preferred. Manufactured from steel to Grade 2 specifications and certified to ASTM A307, it carries a bright uncoated finish. This box contains 50 bolts, sold as a single package unit.

This bolt is a standard inch-series fastener used in light to moderate structural and mechanical connections in residential and commercial trade work. Partial threading allows the unthreaded shank to span the material being joined before engaging the nut or tapped hole, reducing the risk of thread binding in thicker assemblies. Typical applications include equipment mounting, bracket attachment, duct framing supports, pipe hanger assemblies, and general sheet metal or structural steel connections.

Key Features

• 1/4-20 UNC thread size for broad compatibility with standard inch-series nuts and tapped holes
• 3-3/4 inch length under head suits through-bolt applications with moderate material stack thickness
• Partially threaded shank reduces thread binding in thicker clamped joints
• Grade 2 steel construction meets ASTM A307 standard for general-purpose fastening
• Bright uncoated finish — suitable for dry interior environments; apply appropriate coating where corrosion resistance is required
• Sold in a minimum order quantity of 50 pieces per box for shop stock and service van replenishment

Compatibility

Designed as a general-purpose OEM-style replacement or service fastener for any assembly specifying a 1/4-20 UNC hex head bolt at 3-3/4 inches length under head, Grade 2, ASTM A307, in inch-measurement systems.

Installation Notes

Installation is appropriate for qualified tradespeople including HVAC technicians, plumbers, electricians, and pipefitters. Always de-energize electrical systems and isolate mechanical equipment before servicing fastened assemblies. Use the correct hex driver or wrench size for 1/4-20 hardware and torque to values specified by the equipment manufacturer or applicable code. Because this bolt carries a bright uncoated finish, avoid use in wet or corrosive environments without additional protective measures such as coating or pairing with appropriate hardware.
