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

Product Description

The VALUE COLLECTION SHB-1420-750-AS is a hex socket cap screw engineered for secure, high-torque fastening in mechanical assemblies, fixtures, and equipment. It features a 1/4-20 UNC thread size with a 3/4-inch length under head and is fully threaded along its entire shank. Constructed from alloy steel with a black oxide coating, it delivers solid tensile strength and moderate corrosion resistance. This fastener is driven with a hex key or Allen wrench, making it well suited for recessed or close-clearance installations where a standard hex head wrench cannot reach. Machinists, millwrights, and maintenance technicians commonly specify this style of cap screw across a wide range of industrial and trade applications.

This screw is appropriate for use in light to medium-duty mechanical assemblies including machine frames, brackets, jigs, fixtures, and equipment housings. Its fully threaded shank provides consistent thread engagement across the full grip length, which is especially useful in thin-material applications or where the mating thread goes through the full fastened thickness. The black oxide finish suits indoor and sheltered environments where minimal surface protection is acceptable and a low-reflectance appearance is preferred.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard inch-series tapped holes
• 3/4-inch length under head with full threading along the entire shank
• Alloy steel construction provides high tensile and shear strength
• Black oxide coating reduces light reflection and offers light surface protection
• Hex socket drive accepts standard hex keys and Allen wrenches for recessed installations

Compatibility

Designed as a standard-specification hex socket cap screw for use in any application requiring a 1/4-20 UNC internally threaded hole with a 3/4-inch grip length.

Installation Notes

Installation is performed with a hex key or Allen wrench sized to the socket drive. Ensure the mating tapped hole is clean and free of debris before driving. Apply thread lubricant or thread-locking compound as required by the assembly specification. Follow applicable mechanical standards and equipment manufacturer torque guidelines when specifying clamp load.
