Value Collection R57700425 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700425 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also known as roll pins or tension pins, are hollow cylindrical fasteners with a longitudinal slot that allows radial compression during installation. Once seated, the pin exerts outward spring pressure against the bore wall, creating a secure, self-retaining fit without threads or adhesives. This pin measures 7/8 inch in length and 3/32 inch in diameter. It is installed by maintenance technicians, millwrights, and mechanical assemblers in applications where vibration resistance and corrosion resistance are both required.

This slotted spring pin is suited for light-duty mechanical assemblies in corrosive or washdown environments where stainless steel is preferred over carbon steel alternatives. Typical applications include shaft-to-hub alignment, hinge pivots, linkage assemblies, and component retention in pumps, valves, and conveyor systems. The 18-8 stainless steel grade provides good resistance to rust and mild chemical exposure, making it a practical choice for plumbing, pool equipment, and food-adjacent mechanical work.

Key Features

• Slotted design allows radial compression for self-retaining fit in bored holes
• 18-8 stainless steel construction offers corrosion resistance without plating
• 3/32 inch diameter suits light-duty precision assemblies
• 7/8 inch length provides sufficient engagement depth for thin-wall and medium-wall components
• Inch measurement system for compatibility with standard US tooling and gauges
• Does not meet military specifications — commercial-grade application

Compatibility

Designed as a standard commercial-grade slotted spring pin for use in mechanical assemblies requiring a 3/32 inch diameter bore and 7/8 inch pin length in inch-measurement systems.

Installation Notes

Slotted spring pins are typically driven into pre-drilled through-holes or blind holes using a pin punch and hammer or an arbor press. Ensure the bore diameter matches the nominal pin diameter per standard fit tolerances before installation. De-energize and lock out any equipment before servicing assemblies containing these pins. Pins should not be reused after removal, as repeated compression and release cycles reduce spring tension and holding force.
