Value Collection 015227PR Hex Socket Cap Screw 5/16-24 Unf

Product Description

The Value Collection 015227PR is a hex socket cap screw designed for high-strength fastening in mechanical, industrial, and trade applications. This screw features a 5/16-24 UNF thread size with a 5/8-inch length under the head and is fully threaded from tip to head. The 1/4-inch hex drive allows engagement with standard hex keys and Allen wrenches. Constructed from alloy steel with a black oxide finish, it offers solid corrosion resistance and surface hardness suitable for demanding assembly environments. Machinists, millwrights, HVAC equipment assemblers, and general maintenance technicians commonly use this fastener type.

This cap screw is suited for use in precision mechanical assemblies, equipment panels, motor mounting, and structural fastening where a flush or recessed head profile is required. The fine UNF thread pitch provides strong thread engagement and resistance to loosening under vibration, making it appropriate for machinery and equipment subject to operational movement or cycling.

Key Features

• 5/16-24 UNF fine thread for high-strength engagement and vibration resistance
• Fully threaded along the 5/8-inch length under head for maximum thread contact
• 1/4-inch hex drive compatible with standard hex keys and socket drivers
• Alloy steel construction meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards
• Black oxide finish provides moderate corrosion resistance and reduced light reflection
• Low-profile socket head allows installation in recessed or clearance-limited spaces

Compatibility

Designed as a standard-dimension hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574, suitable for use in any application requiring a 5/16-24 UNF fully threaded socket head cap screw with a 1/4-inch hex drive.

Installation Notes

Install using a calibrated 1/4-inch hex key or socket bit; do not use an undersized or worn driver, as this can strip the socket recess. Verify mating thread condition before installation to ensure full thread engagement. Apply appropriate thread-locking compound if the assembly is subject to high vibration. Follow applicable equipment manufacturer torque specifications for the 5/16-24 UNF thread class used in the assembly.
