Value Collection R57700441 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700441 is a slotted spring pin manufactured from 18-8 stainless steel. Spring pins, also called roll pins, are hollow cylindrical fasteners with a longitudinal slot that allows the pin to compress during installation and exert a radial spring force against the host bore. This design creates a secure, vibration-resistant fit without the need for additional locking hardware. At 5/16 inch in length and 1/8 inch in diameter, this pin is suited for light-duty fastening and alignment applications. Maintenance technicians, millwrights, and assembly professionals work with these fasteners across a wide range of mechanical assemblies.

This slotted spring pin is used in mechanical assemblies where a removable yet secure pin is required. Common applications include shaft-to-hub connections, linkage assemblies, and component alignment tasks in equipment maintenance and repair. The 18-8 stainless steel construction provides corrosion resistance, making this pin appropriate for use in humid, wet, or mildly corrosive environments. It is sized for inch-system assemblies and does not meet military specifications.

Key Features

• Slotted spring pin design compresses on installation for a secure interference fit in the bore
• 18-8 stainless steel construction offers corrosion resistance in damp or mildly corrosive environments
• 5/16 inch overall length and 1/8 inch diameter for light-duty fastening and alignment work
• Inch-system dimensioning for compatibility with standard inch-specification assemblies
• Does not meet military specifications — intended for commercial and industrial applications

Compatibility

Designed as an OEM-style replacement or maintenance stock pin for commercial and industrial mechanical assemblies requiring a 1/8 inch diameter slotted spring pin in an inch-measurement system.

Installation Notes

Installation is performed with a pin punch and hammer or an arbor press — ensure the receiving bore is clean and within the appropriate tolerance range for the pin diameter before driving. De-energize and lock out any machinery before servicing components that contain spring pins. Removal typically requires a pin punch slightly smaller than the pin diameter driven from one end. Reuse of spring pins is generally not recommended once removed, as repeated compression cycles can reduce the spring force and retention reliability.
