Value Collection R57700613 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700613 is a slotted spring pin manufactured from 18-8 stainless steel. Spring pins, also called roll pins or tension pins, are cylindrical fasteners with a longitudinal slot that allows the pin to compress during installation and exert outward pressure against the bore wall once seated. This design creates a secure, vibration-resistant fit without adhesives or secondary locking hardware. At 3-1/2 inches in length and 1/4 inch in diameter, this pin is suited for medium-duty mechanical assemblies where corrosion resistance is a priority. Machinists, millwrights, and maintenance technicians are the primary installers.

This slotted spring pin is used in residential and light industrial mechanical assemblies including hinges, linkages, clevis joints, shafts, and alignment fixtures where a removable or semi-permanent cylindrical fastener is required. The 18-8 stainless steel construction makes it appropriate for wet, humid, or mildly corrosive environments where carbon steel pins would corrode. It is a common replacement or service fastener in pump assemblies, valve linkages, and general mechanical sub-assemblies encountered by plumbers, HVAC techs, and equipment mechanics.

Key Features

• Slotted design compresses on insertion for a self-retaining, vibration-resistant fit
• 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• 3-1/2 inch length accommodates deeper bore applications
• 1/4 inch diameter suits standard medium-duty shaft and linkage bores
• Inch measurement system for compatibility with standard US tooling and gauges

Compatibility

Designed as a standard slotted spring pin for use in any mechanical assembly requiring a 1/4 inch diameter by 3-1/2 inch slotted roll pin in 18-8 stainless steel per inch-system specifications.

Installation Notes

Installation is performed with a pin punch and hammer or a hydraulic press, depending on fit tolerance and bore depth. Always de-energize and lock out any equipment before inserting or removing pins from rotating or pressurized assemblies. Use a punch diameter slightly smaller than the pin bore to avoid deforming the bore wall. Removal is accomplished by driving the pin through the bore with a punch of appropriate diameter.
