Value Collection R57900603 Slotted Spring Pin 8mm

Product Description

The VALUE COLLECTION R57900603 is a metric slotted spring pin designed for use in mechanical assemblies requiring a reliable, removable fastening solution. Manufactured from 1070-1080 grade carbon steel with a plain finish, this pin measures 8 mm in overall length and 3.5 mm in diameter. Slotted spring pins compress slightly during installation, allowing them to create a secure interference fit inside a drilled hole. They are commonly installed by machinists, maintenance technicians, and assembly workers in light and medium-duty mechanical applications.

This pin is suited for metric fastening applications in general industrial and mechanical assembly environments. Its compact size makes it appropriate for use in shaft-to-hub connections, clevis assemblies, gear alignment, and similar setups where a removable or semi-permanent locating pin is needed. The plain steel finish is appropriate for dry or lightly protected indoor environments. The metric dimensioning system makes this pin a direct fit for metric-designed components and fixtures.

Key Features

• Slotted spring design allows radial compression for secure interference fit in drilled holes
• 1070-1080 carbon steel construction provides solid strength for general-duty fastening
• Metric sizing: 8 mm overall length and 3.5 mm diameter
• Plain finish — suitable for interior or protected mechanical environments
• Compact form factor fits tight-clearance assemblies and small mechanical components

Compatibility

Designed as an OEM-style replacement or standard-use slotted spring pin for metric mechanical assemblies requiring a 3.5 mm diameter pin in an 8 mm length.

Installation Notes

Slotted spring pins are typically installed using a pin punch and hammer or a pneumatic press; use of the correct punch diameter prevents deformation of the slot. Ensure the receiving hole is drilled to the appropriate tolerance for a proper interference fit before driving the pin. Wear appropriate eye protection when driving pins with impact tools. Remove all power and relieve any mechanical tension from the assembly before installing or removing fastening pins.
