Value Collection R57700579 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700579 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also called roll pins, are hollow cylindrical fasteners with a longitudinal slot that allows radial compression during installation. This design creates a spring-loaded interference fit inside the host bore, resisting vibration and shock loads without the need for adhesives or locking hardware. At 0.625 inches long and 0.25 inches in diameter, this pin suits light-duty to medium-duty fastening applications. Machinists, maintenance technicians, and assembly professionals install these pins in mechanical assemblies where secure, removable pin retention is required.

This slotted spring pin is used in a wide range of mechanical and industrial applications, including shaft-to-hub connections, pivot points, hinge assemblies, and alignment fixtures. The 18-8 stainless steel construction provides good corrosion resistance, making it suitable for environments with moisture exposure or mild chemical contact. It is appropriate for use in both light machinery and general manufacturing assembly where a standard inch-series fastener is specified. This part ships as a single pin with a minimum order quantity of 100 units.

Key Features

• Slotted design allows radial compression for a secure interference fit in the bore
• 18-8 stainless steel grade provides corrosion resistance for wet or mildly corrosive environments
• 0.625 inches overall length suits compact mechanical assemblies
• 0.25 inches diameter compatible with standard quarter-inch bore applications
• Inch-series measurement system for use with standard imperial tooling and drawings
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed as a standard inch-series slotted spring pin for use in mechanical assemblies requiring a 0.25-inch diameter roll pin in commercial and industrial applications.

Installation Notes

Slotted spring pins are typically installed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. Ensure the bore diameter is within the appropriate tolerance for the pin diameter before installation. Wear appropriate eye protection during installation to guard against pin ejection. To remove, drive the pin through the bore using a punch sized smaller than the pin diameter.
