Value Collection R57700479 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700479 is a slotted spring pin machined from 18-8 stainless steel. Slotted spring pins, also called roll pins, are hollow cylindrical fasteners with a longitudinal slot that allows the pin to compress during installation and exert radial spring force against the bore wall. This design provides a secure, vibration-resistant fit without the need for adhesives or secondary locking hardware. At 9/16 inch long and 5/32 inch in diameter, this pin is suited for light-duty mechanical assemblies requiring reliable retention in a compact form factor. Installed by maintenance mechanics and industrial assembly technicians.

This slotted spring pin is used in mechanical assemblies where a removable, self-retaining fastener is needed to secure shafts, gears, levers, or linkages to a mating component. The 18-8 stainless steel construction provides corrosion resistance, making it appropriate for food-processing equipment, marine hardware, outdoor assemblies, and wet or humid environments. The inch-measurement sizing fits standard fractional tooling and gauging used in North American manufacturing and maintenance operations.

Key Features

• Slotted design compresses on installation for a spring-loaded, self-retaining fit
• 18-8 stainless steel construction resists corrosion in wet and humid environments
• Fractional inch sizing compatible with standard North American tooling
• Reusable and removable without damage to the bore in most applications
• Compact 9/16 inch length suits tight-clearance assemblies

Compatibility

Designed as an OEM-style replacement or maintenance stock slotted spring pin for mechanical assemblies requiring a 5/32 inch diameter, 9/16 inch long fractional-inch roll pin in 18-8 stainless steel.

Installation Notes

Slotted spring pins are installed by maintenance mechanics and assembly technicians using a pin punch and hammer or an arbor press. Always ensure the receiving bore diameter is within the manufacturer tolerance for the pin diameter before driving the pin. Wear eye protection during installation, as pins can eject under compression. To remove, drive the pin through the bore with a properly sized punch rather than attempting to pry it out laterally.
