Value Collection 015245PR Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 015245PR is a hex socket cap screw designed for high-strength fastening applications where a flush or recessed drive profile is required. Sized at 5/16-24 UNF with a 2-1/2 inch length under the head, this fastener is partially threaded and driven with a 1/4 inch hex key. The alloy steel construction with a black oxide finish provides solid mechanical strength and moderate corrosion resistance. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for precision mechanical assemblies, equipment maintenance, and structural fastening tasks performed by machinists, millwrights, and maintenance technicians.

This screw is suited for use in mechanical assemblies, machinery, and equipment where a fine-thread UNF pattern is required for improved thread engagement and vibration resistance. The partial threading allows the unthreaded shank to act as a locating feature in clearance holes. It is commonly used in HVAC equipment frames, pump housings, compressor assemblies, electrical enclosures, and general industrial equipment requiring a clean, recessed drive fastener.

Key Features

• 5/16-24 UNF fine-thread pattern for improved torque retention and vibration resistance
• 2-1/2 inch length under head with partial threading for shank-locating applications
• 1/4 inch hex socket drive for use with standard hex keys or socket drivers
• Alloy steel construction meets ASTM A574 for high tensile strength
• Black oxide coating provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for any mechanical assembly or equipment application requiring a 5/16-24 UNF partially threaded fastener with a 1/4 inch hex drive.

Installation Notes

Installation should be performed by a qualified technician using a properly sized 1/4 inch hex key or socket bit to avoid fastener rounding. Ensure the mating threaded hole is clean and free of debris before installation. De-energize and lock out any equipment before replacing or installing fasteners on live machinery. Apply thread lubricant or thread-locking compound only as specified by the equipment manufacturer.
