Value Collection 011291P Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 011291P is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural components. This fastener features a 3/8-24 UNF thread size with a 1-inch length under head and is fully threaded throughout its shank. Drive engagement is via a 5/16-inch hex socket, compatible with standard Allen keys and hex-drive bit sets. Constructed from alloy steel with a black oxide coating, the screw delivers solid tensile strength and moderate corrosion resistance in controlled environments. It conforms to ASME/ANSI B18.3 and ASTM A574 standards. Machinists, maintenance technicians, and industrial assembly professionals regularly work with this fastener type.

This screw is suited for use in precision mechanical assemblies, machine tooling fixtures, and equipment maintenance where fine-thread engagement and controlled torque are required. The 3/8-24 UNF fine thread pitch provides higher thread engagement per inch compared to coarse-thread variants, making it appropriate for applications where vibration resistance and precise clamping force are priorities. It is a common choice in industrial and OEM assembly environments requiring standardized ASME fasteners.

Key Features

• 3/8-24 UNF fine thread for increased vibration resistance and precise clamping control
• Fully threaded shank provides maximum thread engagement along the entire 1-inch length under head
• 5/16-inch hex socket drive compatible with standard Allen wrenches and hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical strength requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards for socket cap screws

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for mechanical assemblies, fixtures, and equipment requiring a 3/8-24 UNF fine-thread fastener with a 1-inch length under head.

Installation Notes

Installation requires a 5/16-inch hex key or socket drive. Power down or de-energize any equipment before servicing fastened assemblies. Apply thread-locking compound as appropriate for the application to maintain clamp load in high-vibration environments. Follow applicable industry torque guidelines for 3/8-24 alloy steel socket cap screws per ASME standards.
