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

Product Description

The VALUE COLLECTION SHB-1420-500-AS is a hex socket cap screw designed for general mechanical fastening applications across industrial, HVAC, plumbing, and electrical assembly work. It features a 1/4-20 UNC thread size with a 0.5 inch length under head and is fully threaded from the head to the tip. The fastener is manufactured from alloy steel and finished with a black oxide coating, which provides mild corrosion resistance and reduces light reflection. This screw is driven with a standard hex key (Allen wrench) and is suited for use in tight clearance applications where a low-profile socket drive is required.

This screw is used in a wide range of light-to-medium duty assembly and maintenance tasks. Common applications include equipment panel assembly, bracket mounting, motor component fastening, and structural subassembly work found in residential and commercial mechanical systems. The fully threaded design allows consistent clamping along the entire length of the fastener, making it well-suited for thin material stackups. Installers working on HVAC equipment enclosures, electrical panel hardware, and plumbing fixture supports will find this a standard utility fastener for day-to-day service work.

Key Features

• 1/4-20 UNC thread form for broad compatibility with standard inch-series tapped holes
• 0.5 inch length under head, fully threaded for consistent clamping in thin assemblies
• Alloy steel construction provides higher tensile strength compared to standard carbon steel fasteners
• Black oxide finish offers mild corrosion resistance and a non-reflective surface
• Hex socket drive allows installation with a standard hex key in confined or recessed locations

Compatibility

Designed as a standard inch-series hex socket cap screw suitable for any application requiring a 1/4-20 UNC fully threaded fastener with a 0.5 inch length under head.

Installation Notes

Install using a properly sized hex key or Allen driver to avoid rounding the socket recess. Ensure the mating tapped hole is clean and free of debris before fastening. Do not overtighten, as alloy steel socket cap screws can strip small tapped holes in softer base materials. Follow applicable equipment manufacturer torque guidelines and relevant mechanical codes for the assembly being serviced.
