Value Collection C57700139-25 Slotted Spring Pin

Product Description

The VALUE COLLECTION C57700139-25 is a slotted spring pin designed for use in mechanical assemblies requiring a reliable, compressible fastener. Measuring 0.125 inches in diameter and 1 inch in overall length, this pin is manufactured from 1070-1090 alloy steel with a black oxide finish. The slotted design allows the pin to compress upon insertion and expand to grip the bore walls, providing a secure, vibration-resistant connection without the need for adhesives or additional hardware. Maintenance technicians, machinists, and assembly technicians working with general industrial or OEM mechanical components are the typical installers.

This slotted spring pin is suited for general-purpose industrial and mechanical applications where a standard inch-system fastener is required. It is appropriate for use in light to medium-duty assemblies including linkages, hinges, handles, gears, and shaft-to-hub connections. The 1070-1090 alloy steel construction provides good hardness and resilience for repeated insertion and removal cycles. The black oxide finish offers mild corrosion resistance in dry or lightly humid environments. Each package contains 1 pin, with a minimum order quantity of 25 units.

Key Features

• Slotted design compresses on insertion for a secure interference fit in standard bored holes
• 1070-1090 alloy steel construction provides hardness and spring resilience
• Black oxide finish delivers mild corrosion protection and a clean appearance
• 0.125 inch (1/8 inch) diameter in an inch-system measurement standard
• 1 inch overall length suits a wide range of common assembly depths

Compatibility

Designed as a standard inch-series slotted spring pin for general-purpose mechanical assemblies requiring a 0.125 inch diameter roll pin.

Installation Notes

Installation is typically performed by machinists or mechanical assembly technicians using a roll pin punch and hammer or an arbor press. Ensure the receiving bore is clean and properly sized to the pin diameter before driving the pin to avoid damage to the workpiece. Always de-energize or lock out any machinery before servicing components that contain these pins. Do not reuse pins that show signs of cracking or permanent deformation.
