Value Collection R57600520 Shoulder Screw 1/4 in 10-24

Product Description

The VALUE COLLECTION R57600520 is a stainless steel shoulder screw designed for precision fastening applications where a smooth, close-tolerance shank is required. The shoulder measures 0.25 inches in diameter and 3 inches in length, providing a precise bearing surface for pivoting, sliding, or locating components. The 10-24 UNC threaded section secures into a tapped hole while the shoulder protrudes to serve as a shaft, pivot, or guide. Driven by a 1/8-inch hex socket, the low-profile head has a diameter of 0.375 inches and a height of 0.1875 inches. Constructed from 18-8 stainless steel with an uncoated finish, this fastener offers good corrosion resistance for general industrial and mechanical applications. Installed by machinists, maintenance technicians, and mechanical assemblers.

This shoulder screw is suited for use in jigs, fixtures, linkages, and mechanical assemblies where a precision shaft or pivot point is needed. The 3-inch shoulder length accommodates thicker assemblies or applications requiring a longer bearing surface. The 10-24 UNC thread is a common size compatible with standard tapped holes in aluminum, steel, and plastic components. Typical installation environments include light industrial machinery, tooling, and equipment maintenance scenarios requiring reliable stainless steel fasteners.

Key Features

• 0.25-inch shoulder diameter provides a close-tolerance bearing or pivot surface
• 3-inch shoulder length accommodates deeper assemblies and longer bearing runs
• 10-24 UNC thread for engagement with standard tapped holes
• 18-8 stainless steel construction for corrosion resistance in general service environments
• 1/8-inch hex socket drive with a low-profile 0.375-inch diameter head
• Uncoated finish — no plating to affect dimensional tolerances

Compatibility

Designed as a standard shoulder screw for use in fixtures, jigs, linkages, and mechanical assemblies requiring a 1/4-inch shoulder diameter, 3-inch shoulder length, and 10-24 UNC threaded engagement.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 1/8-inch hex key or socket driver. Ensure the mating tapped hole is clean and properly sized for 10-24 UNC thread engagement before driving the screw. Do not overtighten — the shoulder, not the thread, carries the load in most applications. Power down any equipment and relieve all mechanical tension or spring loads in the assembly before replacing or installing shoulder screws.
