Value Collection 015297PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 015297PR is a partially threaded hex socket cap screw designed for secure, high-strength fastening in mechanical and structural assemblies. It features a 3/8-24 UNF thread and measures 1.75 inches in length under the head, making it suitable for applications requiring fine-thread engagement and precision torque. The 5/16-inch hex drive accepts a standard Allen or hex key for installation. Constructed from alloy steel with a black oxide finish, this fastener provides corrosion resistance in moderate environments and meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards. Machinists, millwrights, and maintenance technicians regularly specify this type of fastener where UNF thread pitch is required.

This cap screw is suited for use in machinery, fixtures, tooling, and general mechanical assemblies where a fine-thread, socket-drive fastener is specified. The 3/8-24 UNF thread is commonly used in automotive, aerospace, and industrial equipment applications where vibration resistance and precise clamping force are priorities. The partially threaded shank provides a bearing surface that resists lateral shear loads. This screw is appropriate for use in both original equipment manufacturing and field maintenance applications.

Key Features

• 3/8-24 UNF fine thread for vibration-resistant clamping and precise torque control
• 1.75-inch length under head with partial threading for shear-load bearing
• 5/16-inch hex socket drive compatible with standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides moderate corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application specifying a 3/8-24 UNF partially threaded socket head cap screw with a 1.75-inch length under head.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a calibrated torque wrench and a 5/16-inch hex key or socket bit. Ensure the mating tapped hole is clean and free of debris before threading. De-energize and lock out any equipment before replacing fasteners on machinery per applicable safety procedures. Do not reuse fasteners that show signs of galling, thread damage, or corrosion.
