Value Collection 011297PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 011297PR is a hex socket cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. With a 3/8-24 UNF thread size and a 1-3/4 inch length under head, this fastener is partially threaded and driven with a 5/16 inch hex key. Constructed from alloy steel with a black oxide finish, it delivers solid tensile strength and basic corrosion resistance in demanding service environments. Licensed HVAC and mechanical trades rely on this type of fastener when assembling equipment frames, mounting hardware, and bracketed components that require a clean, recessed drive head.

This screw is suited for general industrial and mechanical assembly work where a fine-thread, high-strength fastener is required. The 3/8-24 UNF thread pitch provides greater thread engagement and resistance to loosening under vibration compared to coarse-thread equivalents, making it a common choice for precision mechanical and trade equipment installations. It is appropriate for both shop fabrication and field service work across HVAC, plumbing, and electrical panel assembly contexts.

Key Features

• 3/8-24 UNF fine thread for high vibration resistance and strong thread engagement
• 1-3/4 inch length under head with partial threading for precise clamping
• 5/16 inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Recessed socket head keeps fastener profile low and clears surrounding components

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for general mechanical assemblies requiring a 3/8-24 UNF partially threaded fastener with a 5/16 inch hex drive.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional using a calibrated hex key or socket bit sized at 5/16 inch. Ensure mating threads are clean and free of debris before driving to prevent cross-threading. Do not exceed the rated torque for the thread size and material grade as specified by ASME/ANSI B18.3 guidelines. Minimum order quantity is 100 units per order.
