Value Collection C57700121-125 Slotted Spring Pin 25pk

Product Description

The VALUE COLLECTION C57700121-125 is a slotted spring pin designed for use in mechanical assemblies where a fastener must absorb shock and vibration through controlled radial compression. Manufactured from 1070/1090 alloy steel with a black oxide finish, this pin measures 0.5 inches in overall length and 1/16 inch in diameter. The slotted design allows the pin to compress upon insertion and exert outward spring force against the bore wall, creating a secure, self-retaining fit without additional fasteners. Machinists, maintenance technicians, and assembly workers install these pins in shafts, linkages, and housings across a wide range of mechanical equipment.

This slotted spring pin is suited for light-duty mechanical assemblies in both industrial and commercial settings. Common applications include pivot points, drive shaft retention, gear and sprocket positioning, and hinge assemblies. The inch measurement system makes it directly compatible with standard imperial-dimensioned components. The black oxide finish provides a degree of corrosion resistance in mildly humid or indoor environments. This item is packaged in a quantity of 25 pins per pack, making it appropriate for both single-use repairs and low-volume production runs.

Key Features

• Slotted spring design compresses radially for a self-retaining fit in the bore
• 1070/1090 alloy steel construction provides strength and moderate hardness
• Black oxide finish offers mild corrosion resistance for indoor applications
• 0.5 inch overall length and 1/16 inch diameter for light-duty fastening tasks
• Inch measurement system for compatibility with standard imperial components
• Packaged in quantities of 25 pins for shop stock or production use

Compatibility

Designed as a standard imperial slotted spring pin for use in mechanical assemblies requiring a 1/16 inch diameter bore and 0.5 inch pin length. Does not meet military specifications.

Installation Notes

Installation is performed by machinists or mechanical technicians using a pin punch and hammer or an arbor press. The receiving bore should be dimensioned to match the pin diameter per standard spring pin tolerances. Always de-energize and lock out any machinery before installing or removing spring pins. Do not reuse a pin that has been removed, as the slotted body may lose its spring tension after a single compression cycle.
