Value Collection 015301PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 015301PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural components. It features a 3/8-24 UNF thread size, a 2-1/2 inch length under head, and a 5/16 inch hex drive. The screw is partially threaded, allowing it to clamp two surfaces without thread engagement in the grip area. Constructed from alloy steel with a black oxide finish, it offers solid corrosion resistance and is suited for use in both shop and field environments. Licensed mechanics, machinists, and maintenance technicians are the typical installers of this fastener type.

This cap screw is used in applications requiring fine-thread engagement, such as precision machinery, hydraulic components, and equipment frames where vibration resistance is important. The 3/8-24 UNF thread pitch provides a tighter thread engagement than coarse-thread equivalents, making it a common choice when working with thin materials or when fine torque adjustment is needed. It is sold in multiples of 10.

Key Features

• 3/8-24 UNF thread for fine-pitch engagement and vibration resistance
• 2-1/2 inch length under head with partial threading for proper clamping
• 5/16 inch hex socket drive for use with standard hex keys or Allen drivers
• Alloy steel construction for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces glare
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard hex socket cap screw for use in any application requiring a 3/8-24 UNF partially threaded cap screw with a 5/16 inch hex drive.

Installation Notes

Installation should be performed by a qualified mechanic or machinist familiar with fine-thread fastener procedures. De-energize or lock out any equipment before accessing fastener locations on powered machinery. Use a calibrated torque wrench and the appropriate 5/16 inch hex key or driver to achieve proper seating without overloading the thread. Avoid cross-threading by starting the screw by hand before applying torque.
