Value Collection HCI20370225-050BX Hex Head Bolt 3/8-16

Product Description

The VALUE COLLECTION HCI20370225-050BX is a 3/8-16 UNC hex head bolt with a 2-1/4 inch length under the head, manufactured from Grade 2 uncoated steel and conforming to ASTM A307. The bolt is partially threaded, meaning the shank runs smooth for a portion of its length before the thread begins — a configuration commonly preferred for bolted connections where clamp load and shear resistance across an unthreaded shank are required. This fastener is sold in a minimum-order quantity of 50 pieces, making it suitable for trade accounts stocking hardware for mechanical, structural, or utility installations.

This bolt is used across general mechanical assembly, light structural connections, plumbing supports, electrical conduit hangers, HVAC equipment mounting, and similar trade applications where ASTM A307 Grade 2 fasteners are specified. It is appropriate for indoor and covered-outdoor installations where corrosion protection is not a code or design requirement, as the finish is bright and uncoated. Plumbers, electricians, HVAC technicians, and general mechanical contractors commonly source fasteners of this type in bulk for recurring service and installation work.

Key Features

• 3/8-16 UNC thread form — standard coarse-thread pitch for broad tool and nut compatibility
• 2-1/4 inch length measured under the head per standard fastener convention
• Partially threaded shank for applications requiring an unthreaded bearing surface
• Grade 2 steel, ASTM A307 compliant — meets widely referenced general-purpose structural bolt specifications
• Bright uncoated finish — no plating, suitable for dry or protected environments
• Sold in multiples of 50 for efficient bulk stocking

Compatibility

Designed for use with standard 3/8-16 UNC hex nuts and washers in general mechanical and light structural assemblies where ASTM A307 Grade 2 fasteners are specified.

Installation Notes

Installation should follow applicable code requirements, including AISC or IBC provisions when used in structural connections. Use a calibrated torque wrench when a specific clamp load is required by the design engineer or applicable standard. Verify that mating nuts and washers are also rated for the intended load and finish environment. Uncoated fasteners should not be used in wet, corrosive, or exterior-exposed conditions without additional corrosion protection.
