Value Collection R57700669 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700669 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also called roll pins, are cylindrical fasteners with a longitudinal slot that allows the pin to compress radially during installation and spring back to grip the bore wall. This design creates a secure, vibration-resistant fit without requiring adhesives or secondary locking hardware. The R57700669 measures 1-3/4 inches in length and 1/2 inch in diameter, making it suitable for medium-load retention applications. Installation is handled by maintenance technicians, millwrights, and mechanical assemblers working across a range of industrial and mechanical systems.

This slotted spring pin is used in mechanical assemblies where a removable or semi-permanent pin connection is required between shafts, linkages, brackets, or housings. The 18-8 stainless steel construction resists corrosion in wet, chemical-exposure, or outdoor environments, extending service life compared to carbon steel alternatives. Typical applications include machine tool components, conveyor systems, agricultural equipment, and general-purpose industrial assemblies where dimensional precision and corrosion resistance are both required.

Key Features

• 1-3/4 inches overall length with 1/2 inch diameter for medium-load retention duty
• Slotted (roll pin) design compresses radially on installation for a secure interference fit
• 18-8 stainless steel construction provides corrosion resistance in wet and chemical environments
• Inch system of measurement for compatibility with standard SAE tooling and bore sizing
• Does not meet military specifications — intended for commercial and industrial applications

Compatibility

Designed as an OEM-style replacement or service pin for mechanical assemblies requiring a 1/2 inch diameter slotted spring pin in the inch measurement system.

Installation Notes

Slotted spring pins are installed using a pin punch and hammer or an arbor press — never use an impact driver or torch, as either can deform the slot geometry. Ensure the receiving bore is clean, free of burrs, and sized to the correct toleranced diameter before driving the pin. When removing a spring pin for service, use the appropriate pin punch diameter to avoid expanding the bore. Always wear eye protection during installation and removal.
