Value Collection R57900881 Slotted Spring Pin 50mm

Product Description

The VALUE COLLECTION R57900881 is a slotted spring pin designed for use in mechanical assemblies where a compressible, load-bearing pin is required. Manufactured from 1070-1080 grade carbon steel with a plain finish, this pin measures 50 mm in overall length and 12 mm in diameter. The slotted design allows the pin to compress during insertion and expand to grip the bore walls, providing a secure, vibration-resistant fit without adhesives or secondary fasteners. It is installed by millwrights, machine technicians, and maintenance professionals working on industrial and mechanical systems.

This slotted spring pin is suited for metric-dimensioned assemblies across a range of industrial and mechanical applications, including machinery, tooling fixtures, hinges, and component alignment tasks. The metric sizing and 1070-1080 steel construction make it appropriate for applications requiring moderate strength and dimensional accuracy. It is sold individually but subject to a minimum order quantity of 25 units, making it well suited for maintenance shops and facilities that stock fasteners in bulk.

Key Features

• Slotted design compresses on insertion and exerts radial force to hold position in bore
• 50 mm overall length in metric dimensioning
• 12 mm diameter for use in matching metric bores
• 1070-1080 grade carbon steel construction for moderate-strength applications
• Plain finish with no coating or plating
• Does not meet military specifications

Compatibility

Designed for use in metric-dimensioned mechanical assemblies requiring a 12 mm diameter slotted spring pin with a 50 mm length. Verify bore tolerance and material requirements before installation.

Installation Notes

Slotted spring pins are typically installed using a pin driver and hammer or a hydraulic press, depending on bore depth and material hardness. Ensure the receiving bore is clean, properly sized to metric tolerance, and free of burrs before driving the pin. De-energize and lock out any machinery before performing pin installation or removal. Do not re-use a spring pin that has been fully removed, as repeated compression cycles can reduce retention force.
