Value Collection SHN-1420-500-AS Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION SHN-1420-500-AS is a hex socket cap screw designed for fastening applications that require a recessed drive and a clean, low-profile head. Threaded 1/4-20 UNC and measuring 1/2 inch in length under the head, this screw is fully threaded along its entire shank. It is manufactured from alloy steel and finished with a black oxide coating, which provides mild corrosion resistance and reduces light reflection. Machinists, millwrights, fabricators, and maintenance technicians use socket cap screws in machine assemblies, fixtures, jigs, and equipment panels where a hex key drive is preferred over an external-drive fastener.

This screw is suited for general industrial and mechanical fastening tasks in both light and heavy manufacturing environments. The 1/4-20 UNC thread is a widely used coarse-thread standard, making this screw compatible with a broad range of tapped holes in steel, aluminum, and other metals. The fully threaded design maximizes thread engagement across the full 1/2 inch length, which is especially useful in thin-material or shallow-hole applications. It is appropriate for use in machine frames, bracket mounting, panel assembly, and maintenance repair operations.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• 1/2 inch length under head with full threading along the entire shank
• Alloy steel construction for strength in mechanical fastening applications
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Hex socket drive requires a standard hex key or Allen wrench for installation

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any application requiring a coarse-thread fastener of this size and drive type in tapped steel, aluminum, or similar metal components.

Installation Notes

Installation requires a properly sized hex key or Allen wrench matching the socket drive of this screw. Ensure the receiving tapped hole is clean and free of debris before threading to avoid cross-threading or galling. Do not overtighten, as alloy steel fasteners in softer base materials such as aluminum can strip threads. Follow applicable industry torque guidelines for 1/4-20 fasteners based on the joint material and application requirements.
