Value Collection R57900655 Slotted Spring Pin 24mm

Product Description

The VALUE COLLECTION R57900655 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins, also called roll pins, are hollow cylindrical fasteners with a lengthwise slot that allows the pin to compress during installation and exert radial spring force against the bore walls once seated. This design creates a secure, self-retaining fit without the need for additional hardware. The R57900655 measures 24 millimeters in overall length and 4 millimeters in diameter. It is a metric-dimensioned component suited for mechanical assembly work where reliable pinning of shafts, gears, levers, and linkages is required.

This slotted spring pin is used in general industrial and mechanical assembly applications. It is appropriate for machine maintenance, equipment repair, and production assembly in manufacturing environments. The metric sizing makes it well suited for machinery and components designed to metric specifications. Machinists, millwrights, maintenance technicians, and mechanical assemblers commonly work with this type of fastener. The plain steel finish is standard for interior or protected installations where corrosion exposure is minimal.

Key Features

• Slotted design allows radial compression for self-retaining fit in bored holes
• 1070-1080 carbon steel construction provides good strength and toughness for pinning applications
• 24 millimeter overall length suits a range of hub and shaft thicknesses
• 4 millimeter diameter fits metric-standard bored holes
• Plain finish for standard interior mechanical assemblies
• Metric system of measurement for compatibility with metric-dimensioned components

Compatibility

Designed as a standard metric slotted spring pin for general mechanical assembly applications requiring a 4 millimeter diameter roll pin with 24 millimeter length.

Installation Notes

Slotted spring pins are installed by mechanical assemblers and maintenance technicians using a pin punch and hammer or a hydraulic press. The receiving bore should be drilled to the nominal pin diameter to ensure proper interference fit. Ensure all machinery is de-energized and moving components are secured before installation or removal. Avoid reusing spring pins that have been removed, as repeated compression cycles can reduce clamping force.
