Value Collection 015275PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 015275PR is a hex socket cap screw engineered for high-strength fastening in mechanical, structural, and industrial applications. Manufactured from alloy steel with a black oxide finish, this fastener delivers reliable clamping force and corrosion resistance in demanding environments. The 3/8-16 UNC thread size and 3.5-inch length under head make it well suited for moderate- to heavy-duty assemblies. Drive engagement is through a 5/16 inch hex socket. Partial threading provides full thread engagement in blind-hole applications, ensuring consistent load distribution across the joint.

This cap screw is used in a wide range of trade and industrial settings, including HVAC equipment assembly, pipe support structures, machinery mounting, and electrical enclosure fabrication. The partially threaded shank is particularly useful when fastening two or more components of varying thickness, allowing the unthreaded shank to bear shear loads. Installers working in fabrication shops, mechanical rooms, or field service will find this fastener appropriate for standard and metric-adjacent structural connections where UNC threading is specified.

Key Features

• 3/8-16 UNC thread form meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards
• 3.5-inch length under head accommodates stacked or thicker material assemblies
• Partially threaded shank improves shear load performance in through-bolt applications
• Alloy steel construction provides high tensile strength for demanding fastening conditions
• Black oxide finish offers mild corrosion resistance and reduces light reflection in service environments
• 5/16 inch hex drive is compatible with standard socket sets and hex key wrenches

Compatibility

Designed for use in standard 3/8-16 UNC tapped holes per ASME/ANSI B18.3 specifications, compatible with alloy steel, carbon steel, and cast iron mating components in industrial and mechanical assemblies.

Installation Notes

Installation is performed with a 5/16 inch hex key or socket driver. Always confirm thread engagement in the mating tapped hole before applying torque to avoid cross-threading. Ensure mating surfaces are clean and free of debris prior to assembly. For structural applications, consult applicable mechanical or building codes to verify fastener grade and torque requirements.
