Value Collection R57900711 Slotted Spring Pin 55mm 5mm Steel

Product Description

The VALUE COLLECTION R57900711 is a slotted spring pin manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins, also called slotted roll pins, are cylindrical fasteners with a lengthwise slot that allows the pin to compress during insertion and exert radial force against the bore wall. This spring tension locks the pin in place without threads or adhesives. The R57900711 measures 55 mm in overall length and 5 mm in diameter, making it well suited for light- to medium-duty retention and alignment applications. Machinists, millwrights, and maintenance technicians install these pins in production and field-repair environments.

This slotted spring pin is sized for metric fastening applications in industrial machinery, mechanical assemblies, and general manufacturing environments. Typical uses include shaft-to-hub connections, gear retention, hinge pivots, and component alignment tasks where a reusable, self-retaining fastener is preferred over solid or grooved pins. The plain finish is suitable for interior or protected assemblies where corrosion exposure is limited. This part is sold individually and is ordered in multiples of 100.

Key Features

• 1070-1080 grade steel construction provides reliable spring tension and shear strength
• Slotted design allows radial compression for tool-driven or press-fit installation
• 55 mm overall length in a metric-standard 5 mm diameter
• Plain finish for use in dry or protected interior assemblies
• Self-retaining design requires no threads, clips, or adhesives
• Reusable and removable with standard pin punches or drift tools

Compatibility

Designed as a standard metric slotted spring pin for use in machinery, equipment assemblies, and mechanical components requiring a 5 mm bore diameter and 55 mm pin length.

Installation Notes

Slotted spring pins are installed by millwrights, machinists, and maintenance technicians using a pin punch and hammer or an arbor press. Ensure the receiving bore is clean, properly sized, and free of burrs before installation. Align the slot with the direction of applied load where load direction is a design consideration. To remove, drive the pin through the bore using a punch of appropriate diameter or extract with a pin extractor tool.
