Value Collection R57900795 Slotted Spring Pin 40mm 8mm Steel

Product Description

The VALUE COLLECTION R57900795 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins, also known as roll pins, feature a longitudinal slot that allows the pin to compress during installation and exert outward spring force against the bore wall, creating a secure, vibration-resistant fit without adhesives or secondary fasteners. This pin measures 40 millimeters in overall length with an 8 millimeter diameter. It is a metric-dimensioned fastener suited for use in assemblies where axial or rotational retention is required. Maintenance technicians, millwrights, and mechanical assemblers install this type of pin in production and repair settings.

Slotted spring pins of this size are used in a wide range of mechanical assemblies including shaft-to-hub connections, linkages, hinges, and alignment fixtures across industrial, agricultural, and general manufacturing applications. The 8 millimeter diameter and 40 millimeter length make this pin appropriate for medium-duty assemblies where a metric fastener is specified. This pin does not meet military specifications and is intended for standard commercial and industrial use. It is sold individually, with a minimum order quantity of 50 pieces per order.

Key Features

• Slotted design compresses on insertion for a self-retaining, vibration-resistant fit in standard bores
• 1070-1080 carbon steel construction provides reliable strength for general-duty fastening applications
• Plain finish suitable for dry or lightly lubricated environments
• Metric dimensioned at 8 millimeters diameter and 40 millimeters length for use where metric fasteners are specified
• No secondary locking hardware required after proper installation

Compatibility

Designed as a standard metric slotted spring pin for general mechanical assemblies requiring an 8 millimeter diameter, 40 millimeter length roll pin in a carbon steel grade.

Installation Notes

Slotted spring pins are typically installed by millwrights or mechanical technicians using a pin punch and hammer or a hydraulic press, depending on fit tolerance and assembly requirements. Always de-energize, lock out, and tag out any equipment before installing or removing fastening pins from live assemblies. Ensure the bore diameter is clean and free of burrs before driving the pin to avoid damage to the pin slot or bore wall. Do not reuse a spring pin that has been removed, as cycling will fatigue the material and reduce retention force.
