Value Collection 837147PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 837147PR is a hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies and structural applications. Manufactured from alloy steel with a zinc-plated finish, this fastener provides resistance to corrosion while maintaining the tensile strength required in demanding trade environments. The 1/4-20 UNC thread pattern is one of the most common unified coarse thread standards in North American mechanical work. Drive engagement is made with a 3/16-inch hex key. The screw measures 5/8 inches under the head and is fully threaded along its entire length, making it well suited for through-hole and shallow blind-hole applications.

This fastener is used across a wide range of installation scenarios including HVAC equipment assembly, electrical panel and enclosure mounting, plumbing fixture brackets, and general mechanical maintenance. Fully threaded cap screws of this size are commonly found in light structural connections, motor mounts, and equipment frames where a flush or recessed socket head is preferred over a hex-head fastener. The zinc finish meets ASTM B695 requirements, making it appropriate for indoor and light-duty outdoor environments. This SKU is sold individually but must be ordered in multiples of 100.

Key Features

• 1/4-20 UNC thread — widely compatible with standard inch-series tapped holes
• Fully threaded 5/8-inch length under head for maximum thread engagement in shallow applications
• Alloy steel construction for higher tensile strength versus standard carbon steel
• Zinc-plated finish per ASTM B695 for corrosion resistance in indoor and light-duty outdoor use
• 3/16-inch hex socket drive for use with standard hex keys and socket drivers
• Low-profile socket cap head allows recessed installation in counterbored holes

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any application requiring a 1/4-20 inch-series tapped hole and a 3/16-inch hex drive fastener.

Installation Notes

Install and remove using a 3/16-inch hex key or Allen-style socket driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Power down or de-energize any equipment before accessing fastened assemblies during service. Do not exceed the load ratings of the mating material, particularly when threading into aluminum or plastic.
