Value Collection SHN-1420-750-AS Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION SHN-1420-750-AS is a hex socket cap screw with a 1/4-20 UNC thread and a 3/4-inch length under the head. It is fully threaded along its entire shank and manufactured from alloy steel with a black oxide coating. The black oxide finish provides mild corrosion resistance and reduces surface glare. This fastener is driven with a hex key (Allen wrench) and is a standard choice for machine assembly, equipment maintenance, and precision fabrication work. Machinists, millwrights, and maintenance technicians commonly install this type of screw in tight clearance applications where a low-profile head is required.

This screw is suited for general industrial and mechanical assembly where a 1/4-20 UNC thread pattern is specified. It is appropriate for use in metal-to-metal fastening in light machinery, fixtures, tooling plates, and structural brackets. The fully threaded configuration provides consistent thread engagement along the full length of the fastener, making it well-suited for thinner material applications. It is compatible with standard 1/4-20 UNC threaded holes and mating nuts.

Key Features

• 1/4-20 UNC thread form for compatibility with standard inch-series threaded holes
• 3/4-inch length under head for consistent fastener depth in typical machine applications
• Fully threaded shank maximizes thread engagement in thin material assemblies
• Alloy steel construction provides high tensile strength for mechanical fastening
• Black oxide coating offers mild corrosion resistance and a matte appearance
• Hex socket drive allows installation in confined spaces with a standard Allen key

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 1/4-20 UNC hex socket cap screw with a 3/4-inch length under head and fully threaded shank.

Installation Notes

Install using a correctly sized hex key or Allen driver to avoid rounding the socket drive. Ensure the mating threaded hole is clean and free of debris before installation. Apply thread-locking compound or fastener lubricant as required by the application specifications. Follow applicable mechanical assembly standards and torque guidelines specified by the equipment manufacturer for 1/4-20 UNC fasteners.
