Value Collection 011223P Hex Socket Cap Screw 5/16-18 Unc

Product Description

The Value Collection 011223P is a hex socket cap screw designed for high-strength bolted connections in mechanical, industrial, and structural assemblies. It features a 5/16-18 UNC thread size with a 3-1/2 inch length under the head and is partially threaded, which allows the unthreaded shank to bear shear loads while the threaded portion engages the mating material. Manufactured from alloy steel with a black oxide coating, this fastener delivers corrosion resistance and a consistent surface finish suitable for demanding service environments. Drive is 1/4 inch hex, compatible with standard hex keys and socket drive tools. Installation is typically performed by maintenance technicians, machinists, and general tradespeople working with metal fabrications, fixtures, or equipment assemblies.

This screw is suited for use in light industrial machinery, equipment mounting, jig and fixture fabrication, and general mechanical assembly where a flush or recessed fastener head is required. The alloy steel construction and black oxide finish make it appropriate for dry or lightly oiled indoor environments. The partially threaded shank is particularly useful in applications requiring close-tolerance hole fits or shear-load resistance.

Key Features

• 5/16-18 UNC thread for compatibility with standard inch-series tapped holes
• 3-1/2 inch length under head with partial threading for shear-load applications
• Alloy steel construction for high tensile and yield strength
• Black oxide coating provides mild corrosion resistance and reduces light reflection
• 1/4 inch hex drive for use with standard hex keys or socket tools
• Meets ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application requiring a 5/16-18 UNC fastener with a 3-1/2 inch length under head and 1/4 inch hex drive.

Installation Notes

Installation should be performed with the appropriate 1/4 inch hex key or hex socket driver. Ensure the mating tapped hole is clean and free of debris before driving. Apply thread lubricant or thread-locking compound as required by the application. Do not exceed the rated torque for the fastener grade and thread size per applicable ASME standards.
