Value Collection HCI50370225G-050BX Hex Head Cap Screw

Product Description

The VALUE COLLECTION HCI50370225G-050BX is a 3/8-16 UNC partially threaded hex head cap screw designed for general mechanical and structural fastening applications. Manufactured from Grade 5 steel and finished with a hot-dipped galvanized coating, this fastener delivers solid corrosion resistance and reliable clamping strength in both interior and exterior installations. The 2-1/4-inch length under head and partial thread profile make it well suited for fastening thicker assemblies where a grip length without full thread engagement is required. Tradespeople working in HVAC, plumbing, electrical, and general construction will find this screw appropriate for equipment mounting, structural connections, and bracket installations.

This hex head cap screw is used across a wide range of trade and light industrial applications, including equipment mounting, framing connections, and mechanical assembly work. The hot-dipped galvanized finish provides added protection in environments where moisture or outdoor exposure is a factor, making it a practical choice for rooftop HVAC installations, outdoor electrical enclosures, pool equipment mounting, and similar service scenarios. The standard UNC thread form ensures broad wrench and driver tool compatibility on the job site.

Key Features

• Grade 5 steel construction provides dependable tensile and shear strength for structural fastening tasks
• Hot-dipped galvanized finish offers corrosion resistance suitable for outdoor and moisture-prone environments
• Partial thread design provides a smooth grip length for fastening thicker material assemblies
• 3/8-16 UNC thread standard ensures compatibility with standard nuts, inserts, and tapped holes

Compatibility

Designed as a standard 3/8-16 UNC Grade 5 hex head cap screw for use with any matching UNC nut, flat washer, or tapped hole of the same thread size and pitch.

Installation Notes

Install using a standard hex wrench, socket, or impact driver sized for a 3/8-inch hex head cap screw. Ensure the mating nut or tapped hole is the same 3/8-16 UNC thread standard before installation to avoid cross-threading. Torque to values appropriate for Grade 5 fasteners at this diameter per the applicable mechanical or building code reference for the application. Use appropriate washers under the head when fastening soft or uneven surfaces to distribute clamping load.
