Value Collection R57600516 Shoulder Screw 1/4 in 18-8 Ss

Product Description

The VALUE COLLECTION R57600516 is an 18-8 stainless steel shoulder screw designed for precision fastening applications where a smooth, close-tolerance shaft is required. The shoulder measures 0.25 inches in diameter and 2.5 inches in length, providing a controlled bearing or pivot surface. The threaded portion is sized at 10-24 UNC, and the head is driven by a 1/8 inch hex socket key. The uncoated 18-8 stainless steel construction provides corrosion resistance suitable for wet, washdown, or mildly corrosive environments. This fastener is installed by machinists, maintenance technicians, and assembly personnel in industrial and mechanical applications.

Shoulder screws of this type are commonly used as pivot pins, guide shafts, or spacers in mechanical assemblies, jigs, fixtures, linkages, and hinges. The 0.25 inch shoulder diameter is suited for components requiring a precision-fit bearing bore. Applications span light industrial machinery, instrumentation, and mechanical linkage systems where a hardened or stainless shoulder fastener is specified. This screw is sold individually but must be ordered in multiples of five to meet the minimum order quantity.

Key Features

• 0.25 inch shoulder diameter provides a close-tolerance bearing or pivot surface
• 2.5 inch shoulder length accommodates deeper component stacks or longer pivot spans
• 10-24 UNC thread for standard compatibility with inch-series tapped holes
• 1/8 inch hex socket drive for use with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction resists corrosion in wet or mildly corrosive environments
• Uncoated finish maintains dimensional accuracy at the shoulder

Compatibility

Designed as a standard inch-series shoulder screw for use in mechanical assemblies, fixtures, and linkage systems requiring a 0.25 inch shoulder diameter and 10-24 UNC threaded end.

Installation Notes

Install using a 1/8 inch hex key or matching hex socket bit. Ensure the mating bore diameter matches the 0.25 inch shoulder for proper fit and function. Do not overtighten the threaded section into the tapped hole, as the shoulder face is intended to seat flush against the mating component. Verify thread engagement depth meets design requirements before final assembly.
