Value Collection HCI20370500G-025BX Hex Head Bolt 3/8-16 5in

Product Description

The VALUE COLLECTION HCI20370500G-025BX is a Grade 2 steel hex head bolt with a 3/8-16 UNC thread and a 5-inch length under head. It features a hot-dipped galvanized finish for corrosion resistance in outdoor, wet, or exposed installations. The bolt is partially threaded, which provides a smooth shank section for applications requiring precise clamping without thread engagement along the full length. This fastener meets ASTM A307 standards and is appropriate for general-purpose structural and mechanical connections. Plumbers, electricians, HVAC techs, pool service pros, and general contractors reach for this bolt when assembling equipment supports, mounting brackets, or utility connections where a standard inch-series hex bolt is specified.

This bolt is suited for light-to-medium structural applications in residential and commercial trade work. The 3/8-16 UNC thread is one of the most common inch-series fastener sizes in HVAC equipment mounting, pipe hanger assemblies, electrical enclosure hardware, and pool equipment installations. The hot-dipped galvanized coating makes it a practical choice for outdoor use, humid mechanical rooms, rooftop curb installations, and other environments where bare steel would corrode prematurely. Sold in a minimum quantity of 25 per order.

Key Features

• 3/8-16 UNC thread - one of the most common inch-series sizes across trade applications
• 5-inch length under head for deeper grip or longer clamping stack requirements
• Partially threaded shank provides a smooth bearing section for cleaner clamping
• Hot-dipped galvanized finish for corrosion resistance in outdoor and humid environments
• Grade 2 steel construction meets ASTM A307 fastener standards
• Inch measurement system - direct fit where imperial fasteners are specified

Compatibility

Designed as a general-purpose Grade 2 hex head bolt for standard inch-series fastener applications requiring a 3/8-16 UNC thread and 5-inch length under head.

Installation Notes

Install with a standard 9/16-inch hex wrench or socket driver appropriate for 3/8-16 hardware. Always power down or de-energize equipment before fastening or removing mounting hardware on electrical or HVAC components. Use flat washers and lock washers as required by the application to prevent loosening under vibration. Do not exceed the load ratings appropriate for Grade 2 fasteners - consult project specifications or applicable codes when structural loading is a factor.
