Value Collection R57900547 Slotted Spring Pin 18mm 1070-1080 Steel

Product Description

The VALUE COLLECTION R57900547 is a slotted spring pin manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins, also called roll pins, are hollow cylindrical fasteners with a longitudinal slot that allows the pin to compress on insertion and exert outward spring force against the bore wall. This self-retaining design eliminates the need for additional locking hardware. The R57900547 measures 18 mm in overall length with a 2.50 mm diameter and is sized to metric specifications. Maintenance technicians, millwrights, and assembly line personnel install these pins in mechanical assemblies to secure shafts, link pivot points, or retain components in drilled holes.

This slotted spring pin is suited for light-duty mechanical assemblies requiring a metric fastener. Common applications include shaft-to-hub connections, linkage pivot pins, and retention applications in machine frames, fixtures, and manufactured equipment. The metric sizing makes this pin a fit for equipment produced to international dimensional standards. The plain steel finish is appropriate for indoor or protected installations where corrosion exposure is limited.

Key Features

• 1070-1080 grade steel construction for consistent hardness and spring characteristics
• Slotted design allows radial compression for self-retaining installation without additional hardware
• 18 mm overall length in metric sizing
• 2.50 mm diameter for use in precisely drilled metric bores
• Plain finish suitable for protected indoor mechanical environments

Compatibility

Designed as a standard metric slotted spring pin for use in mechanical assemblies requiring an 18 mm long, 2.50 mm diameter roll pin to metric dimensional standards.

Installation Notes

Slotted spring pins are installed by millwrights or maintenance technicians using a pin punch and hammer or a hydraulic press, depending on fit tolerance and bore depth. De-energize and lock out all machinery before pin installation or removal in accordance with applicable OSHA lockout-tagout procedures. Ensure the bore diameter matches the nominal pin diameter before driving the pin to avoid bore damage or pin deformation. Do not reuse pins that have been fully compressed or show cracking along the slot.
