Value Collection 015287PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 015287PR is a hex socket cap screw designed for secure, high-strength fastening in precision mechanical assemblies. This fully threaded fastener features a 3/8-24 UNF thread, a 3/4 inch length under head, and a 5/16 inch hex drive. Manufactured from alloy steel with a black oxide coating, it provides corrosion resistance and a consistent surface finish suitable for demanding industrial and mechanical applications. The black oxide finish also reduces light reflection, which is useful in tooling and fixture environments. Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, confirming dimensional accuracy and mechanical performance.

This cap screw is suited for use in close-tolerance assemblies where a recessed hex drive is required to allow flush or below-surface installation. Common applications include machine tool fixtures, jigs, hydraulic components, and mechanical sub-assemblies where fine thread engagement and high clamp load are critical. The 3/8-24 UNF fine thread pitch provides greater tensile strength and finer adjustment capability compared to coarse thread equivalents. This screw is typically installed by machinists, millwrights, and mechanical assembly technicians working in industrial maintenance, OEM manufacturing, and field equipment service.

Key Features

• 3/8-24 UNF fully threaded for fine-pitch engagement and high tensile strength
• 3/4 inch length under head for controlled grip in standard assembly applications
• 5/16 inch hex socket drive for use with standard hex keys and socket drivers
• Alloy steel construction for high mechanical strength and durability
• Black oxide coating provides corrosion resistance and a non-reflective finish
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards

Compatibility

Designed as a standard hex socket cap screw for use in any mechanical assembly requiring a 3/8-24 UNF fine-thread fastener with a 5/16 inch hex drive and 3/4 inch length under head.

Installation Notes

Installation is typically performed by machinists or mechanical technicians using a calibrated torque wrench and the appropriate 5/16 inch hex key or bit driver. Ensure mating threads are clean and free of debris before installation. Do not mix thread standards; confirm mating thread is UNF before driving. Apply thread lubricant or thread-locking compound as specified by the equipment manufacturer.
