Value Collection R57900779 Slotted Spring Pin 20mm 8mm Steel

Product Description

The VALUE COLLECTION R57900779 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins are cylindrical fasteners with a longitudinal slot that allows the pin to compress during installation and expand against the bore wall, creating a secure, vibration-resistant fit without adhesives or secondary locking hardware. This pin measures 20 mm in length and 8 mm in diameter. It is a metric-dimensioned component suited for mechanical assemblies where precise, reliable retention is required. Maintenance technicians, millwrights, and mechanical assemblers routinely install these pins in production and repair applications.

This slotted spring pin is used in a wide range of light to medium-duty mechanical assemblies including linkages, hinges, gears, levers, and shaft-to-hub connections. The metric sizing makes it appropriate for equipment manufactured to international standards. It is a common replacement or production fastener in industrial machinery, agricultural equipment, and general manufacturing environments where carbon steel and plain finish are acceptable for the operating conditions.

Key Features

• 1070-1080 carbon steel construction for reliable strength in general-duty applications
• 20 mm overall length in metric sizing for international equipment compatibility
• 8 mm diameter provides a solid interference fit in matched bores
• Slotted design allows radial compression during insertion for tool-free retention
• Plain finish suitable for dry or lightly lubricated environments

Compatibility

Designed as a standard metric slotted spring pin for general mechanical assembly and replacement use in equipment with 8 mm bore diameters requiring a 20 mm pin length.

Installation Notes

Slotted spring pins are typically driven into pre-drilled bores using a pin punch and hammer or an arbor press. Ensure the receiving bore diameter matches the pin nominal diameter before installation. Always wear appropriate eye protection when driving pins. Pins should be replaced rather than re-driven once removed, as repeated compression can reduce retention force.
