Value Collection HCI20370250-050BX Hex Head Bolt 3/8-16

Product Description

The VALUE COLLECTION HCI20370250-050BX is a 3/8-16 UNC hex head bolt designed for general fastening applications across a wide range of mechanical and structural assemblies. Manufactured from Grade 2 steel with a bright uncoated finish, this bolt measures 2.5 inches in length under the head and features partial threading along the shank. It conforms to ASTM A307 standards, making it a recognized choice for low-carbon steel bolting in non-critical structural and mechanical connections. Installation requires standard hex wrenches or sockets. This SKU is sold as a box of 50 bolts.

This bolt is appropriate for use in light structural connections, equipment mounting, jig and fixture assembly, and general maintenance applications across industrial, commercial, and trade settings. The 3/8-16 thread size and 2.5-inch under-head length suit a broad range of standard clearance hole configurations. Partial threading leaves an unthreaded bearing surface on the shank, which is preferred in applications where shear loads are present or where a consistent clamping zone is required. Tradespeople in HVAC, plumbing, electrical, and general construction will find this bolt applicable to a variety of routine fastening tasks.

Key Features

• 3/8-16 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• 2.5-inch length under head provides adequate grip length for typical panel and bracket assemblies
• Grade 2 steel construction meets ASTM A307 requirements for low-carbon steel bolts
• Partially threaded shank retains an unthreaded bearing zone for improved shear resistance
• Bright uncoated finish suits indoor and dry-environment applications
• Box quantity of 50 reduces per-unit cost for recurring maintenance and production use

Compatibility

Designed as a general-purpose inch-series hex head bolt compatible with standard 3/8-16 UNC nuts, threaded inserts, and tapped components conforming to ASTM A307 specifications.

Installation Notes

Installation is performed with a standard hex socket or open-end wrench sized for a 3/8-inch hex head bolt. Ensure mating nuts or tapped holes are rated to match or exceed ASTM A307 Grade 2 specifications before assembly. Do not use impact tools at full torque without a torque-limiting method, as Grade 2 bolts have lower proof load values than higher-grade fasteners. Follow applicable code requirements, including AISC and relevant mechanical codes, when used in structural or load-bearing connections.
