Value Collection 837155PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 837155PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, equipment fabrication, and maintenance work. It features a 1/4-20 UNC thread with a 1-1/4 inch length under head and is fully threaded along its entire shank. A 3/16 inch hex drive socket is required for installation. Constructed from alloy steel with a zinc-plated finish, this fastener meets ASTM B695 standards for corrosion resistance and mechanical performance. It is a standard choice for engineers, machinists, and maintenance technicians working with metal assemblies where a recessed drive head and reliable clamping force are required.

This screw is suited for general industrial, commercial, and OEM assembly applications where 1/4-20 UNC threaded fasteners are specified. Typical uses include machine frames, brackets, enclosures, and structural components requiring flush or recessed fastener heads. The zinc-plated finish provides moderate corrosion protection appropriate for indoor and controlled-environment applications. This part is sold as a single screw with a minimum order quantity of 100 units, making it appropriate for production and bulk maintenance purchasing.

Key Features

• 1/4-20 UNC thread for wide compatibility with standard inch-series tapped holes
• 1-1/4 inch length under head, fully threaded for maximum thread engagement
• 3/16 inch hex socket drive for torque application with standard Allen keys or socket drivers
• Alloy steel construction for high tensile and shear strength
• Zinc-plated finish meeting ASTM B695 for corrosion resistance in controlled environments
• Sold individually with a minimum order quantity of 100 units for production and stocking use

Compatibility

Designed as a standard replacement or production fastener for any application specifying a 1/4-20 UNC hex socket cap screw with a 1-1/4 inch length under head and fully threaded shank.

Installation Notes

Installation is performed by machinists, maintenance technicians, or mechanical assemblers using a 3/16 inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before driving the screw. Do not exceed the rated torque range for 1/4-20 alloy steel fasteners as specified by the relevant design standard or equipment manufacturer. Follow applicable mechanical assembly codes and torque specifications as defined by the system designer.
