Value Collection 011224P Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 011224P is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 5/16-18 UNC thread size with a 4-inch length under the head and accepts a 1/4-inch hex drive. Constructed from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and consistent clamping force. Partial threading along the shank provides positive thread engagement while allowing shear loading along the unthreaded portion. Meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for precision-fit and load-rated applications.

This screw is used in a wide range of mechanical and industrial settings, including machine assembly, tooling fixtures, equipment fabrication, and structural fastening. The 5/16-18 UNC coarse thread is a common specification in general manufacturing environments. The black oxide coating makes it well suited for applications where some moisture resistance is needed without the added bulk of plating. Machinists, millwrights, maintenance technicians, and fabricators regularly install this type of fastener in both production and field repair contexts.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes
• 4-inch length under head suits deeper clearance and through-hole assemblies
• Partial threading allows shear load transfer along the unthreaded shank
• 1/4-inch hex socket drive for use with Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 for high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and reduced light reflection

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 5/16-18 UNC partially threaded fastener with a 1/4-inch hex drive.

Installation Notes

Install using a 1/4-inch hex key or hex socket bit driver. Ensure the mating tapped hole is clean and free of debris before driving. De-energize or lock out any powered equipment before performing fastener installation or replacement per applicable LOTO procedures. Do not exceed the rated strength of the fastener by over-torquing; consult applicable fastener torque tables for 5/16-18 alloy steel cap screws.
