Value Collection R57700449 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700449 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 constant outward spring force against the bore wall, keeping the pin firmly seated without adhesives or secondary retention. At 0.625 inches in overall length and 0.125 inches in diameter, this pin is suited for compact assemblies where positive retention in a close-tolerance hole is required. Installed by maintenance technicians, machine builders, and millwrights, these pins are a standard component in mechanical and industrial assemblies.

This slotted spring pin is used in a wide range of mechanical assemblies including shafts, linkages, clevis joints, and pivot connections. The 18-8 stainless steel construction provides corrosion resistance suitable for washdown, outdoor, and light chemical environments. Typical applications include light machinery, food-processing equipment, marine hardware, and general industrial fixtures where a reusable, corrosion-resistant fastener is preferred over carbon steel alternatives. Inch-system dimensioning makes this pin compatible with standard North American tooling and hole specifications.

Key Features

• Slotted design provides constant radial spring force for secure retention in the bore
• 18-8 stainless steel grade offers good corrosion and oxidation resistance
• 0.625 inches overall length suits compact shaft and linkage applications
• 0.125 inches diameter fits standard inch-series drilled holes
• Reusable design allows removal and reinstallation without damage to the pin or bore

Compatibility

Designed as an OEM-style replacement or stock fastener for inch-series mechanical assemblies requiring a slotted spring pin with a 0.125-inch diameter and 0.625-inch length.

Installation Notes

Slotted spring pins are installed by pressing or driving the pin into a drilled hole using a pin punch and hammer or an arbor press. Ensure the bore is clean and free of burrs before installation. Compress the pin along its slot axis during insertion to avoid distorting the bore. Always relieve any mechanical load or tension on the assembly before removing or replacing pins in load-bearing joints.
