Value Collection R57700655 Slotted Spring Pin 3in 3/8in

Product Description

The VALUE COLLECTION R57700655 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 slightly during installation and exert a constant outward spring force against the bore wall. This design creates a secure, vibration-resistant fit without the need for adhesives or secondary locking hardware. The R57700655 measures 3 inches in length with a 3/8 inch diameter. It is suited for general mechanical assemblies, maintenance applications, and equipment repairs across industrial and trade settings.

This slotted spring pin is used in mechanical assemblies where a removable yet secure pin connection is required. Typical applications include shaft-to-hub connections, linkage assemblies, hinge pivot points, and alignment fixtures. The 18-8 stainless steel construction provides good corrosion resistance, making it appropriate for use in moderate-moisture or washdown environments. Machinists, millwrights, maintenance technicians, and equipment repair professionals commonly specify this fastener type for both OEM builds and field repairs.

Key Features

• Slotted design allows radial compression for a self-retaining, vibration-resistant fit in the bore
• 3 inches overall length for applications requiring a longer pin reach
• 3/8 inch diameter for medium-load connections
• 18-8 stainless steel construction provides corrosion resistance in moderate-moisture environments
• Inch measurement system for compatibility with standard tooling and bore sizing

Compatibility

Designed as a general-purpose slotted spring pin for use in mechanical assemblies requiring a 3/8 inch diameter, 3 inch long roll pin in inch-system dimensions.

Installation Notes

Slotted spring pins are typically installed using a pin punch and hammer or a hydraulic press, depending on fit tolerance and bore depth. Always ensure the bore diameter and material are appropriate for the pin size before pressing to avoid bore damage. Use proper eye protection when driving pins manually. To remove, use a correctly sized punch driven from the open chamfered end of the pin.
