Value Collection R57900591 Slotted Spring Pin 32mm 3mm Steel

Product Description

The VALUE COLLECTION R57900591 is a metric slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins are hollow, slotted fasteners designed to compress during installation and exert radial force against the bore wall, locking them in place without adhesive or threading. This pin measures 32 mm in overall length and 3 mm in diameter, making it suitable for light- to medium-duty positioning and alignment applications in assembled mechanical components. Machinists, maintenance technicians, and precision assembly workers install these pins in production and repair contexts where a removable yet secure locating fastener is required.

This slotted spring pin is used in mechanical assemblies where metric fastener standards apply. Typical applications include shaft-to-hub alignment, hinge pinning, and component registration in machinery, tooling fixtures, and light industrial equipment. The metric dimensioning makes this pin well suited for equipment manufactured to international standards. It is installed using a pin punch and hammer or an arbor press, depending on the bore tolerance and required seating depth.

Key Features

• Slotted design allows radial compression for a secure interference fit in the bore
• 1070-1080 grade carbon steel construction provides reliable strength for standard mechanical fastening
• Plain finish — no coating or plating — suitable for dry or lightly lubricated environments
• Metric sizing: 32 mm overall length and 3 mm diameter for compatibility with metric-dimensioned bores
• Does not meet military specifications — intended for commercial and industrial applications

Compatibility

Designed as a standard metric slotted spring pin for use in commercial and industrial mechanical assemblies requiring a 3 mm bore diameter and 32 mm pin length.

Installation Notes

Installation is typically performed by maintenance technicians or machinists using a pin punch and hammer or an arbor press. Ensure the receiving bore is clean and dimensionally correct before driving the pin. Power down and de-energize any equipment before servicing assemblies that contain these pins. Avoid overdriving, which can damage the bore or deform the pin beyond its functional compression range.
