Value Collection -33624-1 Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION -33624-1 is a hex socket cap screw designed for general-purpose fastening in structural and mechanical assemblies. The screw features a 5/16-18 UNC thread size and a partially threaded shank with a length under head of 2.25 inches. Drive engagement is via a 1/4 inch internal hex socket. The alloy steel construction provides high tensile strength suitable for demanding industrial and mechanical applications. A black oxide finish adds mild corrosion resistance and reduces surface reflectivity. This fastener is installed by maintenance technicians, machine assemblers, and trade professionals working with standard imperial fastener specifications.

This screw is suited for use in mechanical equipment, fixtures, and structural hardware assemblies requiring a compact, recessed-drive fastener. The 5/16-18 UNC thread pitch is a widely used imperial coarse-thread standard, making this screw compatible with a broad range of tapped holes and threaded inserts in ferrous and non-ferrous components. Typical applications include panel mounting, machinery frames, and general fabrication work across industrial and commercial settings. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards.

Key Features

• 5/16-18 UNC coarse-thread specification for broad compatibility with standard tapped holes
• 2.25 inch length under head with partial threading for secure clamping grip
• 1/4 inch hex socket drive for use with standard hex keys and socket drivers
• Alloy steel construction delivers high tensile strength per ASTM A574
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-stock hex socket cap screw for applications requiring a 5/16-18 UNC partially threaded alloy steel fastener with a 1/4 inch hex drive.

Installation Notes

Install using a 1/4 inch hex key or socket bit driver. Ensure the receiving tapped hole is clean and free of debris before threading. Follow applicable torque guidelines from the equipment manufacturer or relevant mechanical codes. Always inspect threads for damage before installation and do not overtorque alloy socket cap screws beyond rated specifications.
