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

Product Description

The VALUE COLLECTION SHN-1420-1-AS is a hex socket cap screw designed for secure fastening in mechanical, structural, and equipment assembly applications. It features a 1/4-20 UNC thread pattern and measures 1 inch in length under the head. The screw is fully threaded along its entire shank, maximizing thread engagement for improved holding strength. Constructed from alloy steel with a black oxide finish, it offers solid corrosion resistance in controlled environments. This fastener is installed using a hex (Allen) key driver. It is a standard industrial fastener used by millwrights, maintenance technicians, equipment assemblers, and trade professionals across HVAC, plumbing, and electrical work.

This screw is suited for light to medium-duty fastening tasks in residential and commercial equipment maintenance, panel assembly, and mechanical installations. The 1/4-20 UNC thread is one of the most common unified coarse thread sizes, making this screw a frequent replacement or general-use item in service and maintenance kits. It is appropriate for applications where a recessed hex drive is preferred for torque control and a low-profile cap head is required.

Key Features

• 1/4-20 UNC thread — one of the most widely used coarse thread sizes in trade applications
• 1 inch length under head for standard fastening depth
• Fully threaded shank for maximum thread engagement
• Alloy steel construction for high tensile strength
• Black oxide finish provides mild corrosion resistance in indoor and controlled environments
• Hex socket drive for use with standard Allen keys or hex bit drivers

Compatibility

Designed as a general-purpose 1/4-20 UNC hex socket cap screw suitable for use in equipment assembly, panel mounting, and mechanical fastening applications where a fully threaded alloy steel screw with a hex drive is specified.

Installation Notes

Install using the correct size hex key or Allen bit to avoid rounding the socket. Ensure mating threads are clean and free of debris before installation. Do not overtighten — follow the torque specifications provided by the equipment manufacturer for the mating assembly. For structural or load-bearing applications, verify fastener grade and finish compatibility with the installation environment.
