Value Collection R57900801 Slotted Spring Pin 55mm 8mm Steel

Product Description

The VALUE COLLECTION R57900801 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Spring pins of this type are designed to secure components in assemblies by compressing during insertion and expanding against the bore wall to hold position under load. The slotted design allows radial flexibility, making the pin self-retaining without adhesive or secondary fasteners. At 55 mm in overall length and 8 mm in diameter, this pin suits medium-duty fastening applications across mechanical assemblies and equipment maintenance tasks.

This slotted spring pin is suited for use in general industrial and mechanical assembly applications where a metric-dimensioned, steel retention pin is required. Typical installation scenarios include shaft-to-hub retention, linkage alignment, and hinge-pin applications in machinery, conveyances, and equipment housings. It is commonly installed by mechanical technicians and maintenance professionals working with metric fastener systems in manufacturing, HVAC equipment assembly, and general trade environments.

Key Features

• Slotted design provides radial spring action for self-retaining fit in bored holes
• 1070-1080 carbon steel construction for strength and durability in mechanical assemblies
• 55 mm overall length suitable for medium-depth retention applications
• 8 mm diameter for metric-dimensioned assemblies
• Plain finish suitable for indoor and controlled-environment installations
• Metric system of measurement for compatibility with metric-engineered components

Compatibility

Designed as a standard metric slotted spring pin for use in mechanical assemblies requiring an 8 mm bore diameter and 55 mm pin length.

Installation Notes

Slotted spring pins are typically installed by mechanical technicians using a pin punch and hammer or a dedicated pin press to seat the pin flush or to a specified depth within the bore. Before installation, ensure the mating bore diameter is within the appropriate tolerance for an 8 mm spring pin to allow proper compression and retention. Always de-energize and lock out any equipment before removing or replacing spring pins in live assemblies. Avoid reusing heavily deformed or cracked pins, as repeated compression cycles can reduce retention force.
