Value Collection 015241PR Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 015241PR is a hex socket cap screw designed for fastening applications that require a high-strength, compact drive format. Threaded to 5/16-24 UNF with a 2-inch length under head, this screw is partially threaded and uses a 1/4-inch hex (Allen) drive. Manufactured from alloy steel and finished with a black oxide coating, it resists corrosion in moderate environments while maintaining the tensile strength required for precision mechanical assemblies. This fastener meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it a recognized choice for structural and industrial fastening work.

This cap screw is suited for use in general industrial assembly, machine building, tooling, and equipment maintenance applications where a recessed hex drive is required for torque application in tight spaces. The UNF fine thread pitch provides better thread engagement and vibration resistance compared to coarse thread equivalents, making it appropriate for metal-to-metal fastening in ferrous assemblies. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in production and repair environments.

Key Features

• 5/16-24 UNF fine thread for improved holding strength and vibration resistance
• 2-inch length under head with partial threading for grip-zone clamping
• 1/4-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish provides mild corrosion protection and reduces light reflection
• Compliant with ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard-dimension UNF hex socket cap screw suitable for use wherever ASME/ANSI B18.3 socket head cap screws are specified in ferrous and general industrial assemblies.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 1/4-inch hex key or hex bit driver. Ensure the mating threaded hole is clean and free of debris before installation. Do not overtighten without reference to engineering torque specifications for the assembly. Verify thread compatibility with the receiving material before installation to avoid galling or cross-threading.
