Value Collection R63002842 Shoulder Screw 5/16 in 1/4-20

Product Description

The VALUE COLLECTION R63002842 is a shoulder screw machined from 18-8 stainless steel, designed for applications that require a precision shoulder to act as a pivot, shaft, or alignment pin. The shoulder measures 0.3125 inches (5/16 inch) in diameter and 1 inch in length, providing a smooth, ground bearing surface. The threaded section carries a 1/4-20 UNC thread form for secure fastening into tapped holes. A 5/32-inch hex socket drive allows installation with a standard Allen wrench or hex bit. Machinists, assembly technicians, and maintenance tradespeople install these fasteners wherever a controlled-diameter shank is needed within a mechanical assembly.

This shoulder screw suits light-to-medium mechanical assemblies across industrial, commercial, and trade applications. Common use cases include use as a pivot point for linkages, a guide for sliding components, a spacer shaft in panel assemblies, and a locating pin in jigs or fixtures. The 18-8 stainless steel construction provides corrosion resistance suitable for environments with incidental moisture exposure, including HVAC equipment panels, plumbing fixture assemblies, and electrical enclosure hardware. This item is sold individually but must be ordered in multiples of 10.

Key Features

• Precision 5/16-inch (0.3125-inch) shoulder diameter provides a reliable bearing and pivot surface
• 1-inch shoulder length accommodates standard-depth linkage and guide applications
• 1/4-20 UNC threaded end for secure engagement in standard tapped holes
• 5/32-inch hex socket drive for installation with Allen keys or hex bits
• 18-8 stainless steel construction offers corrosion resistance for wet or humid environments

Compatibility

Designed as a standard shoulder screw replacement or upgrade for mechanical assemblies requiring a 5/16-inch shoulder diameter, 1-inch shoulder length, and 1/4-20 UNC thread specification.

Installation Notes

Installation requires a 5/32-inch hex key or hex socket driver. Ensure the receiving tapped hole is clean and threads are in good condition before installation. Do not overtighten — shoulder screws used as pivot or guide pins should be snug but allow the intended rotational or sliding movement of mating components. Minimum order quantity is 10 units.
