Value Collection R57700711 Slotted Spring Pin Alloy Steel

Product Description

The VALUE COLLECTION R57700711 is a slotted spring pin designed for use in mechanical assemblies where a reliable, self-retaining fastener is required. Manufactured from 1070-1090 alloy steel with a plain finish, this pin measures 0.125 inches in diameter and 0.375 inches in overall length. The slotted design allows the pin to compress on insertion and expand against the bore wall, providing secure retention without adhesives or secondary fasteners. It is installed by maintenance technicians and machine builders working on light-to-medium duty assemblies in manufacturing, industrial, and general mechanical applications.

This slotted spring pin is suited for use in shaft-to-hub connections, linkage assemblies, and component alignment tasks where a standard inch-series pin is specified. Its compact diameter and short length make it appropriate for close-tolerance bores in smaller mechanical components. The plain finish offers adequate corrosion resistance for indoor and controlled-environment applications. This part does not meet military specifications and is intended for commercial-grade applications.

Key Features

• Slotted spring design compresses for easy insertion and expands to lock in place
• 1070-1090 alloy steel construction provides solid shear strength for commercial-grade use
• 0.125 inch diameter and 0.375 inch length for compact bore applications
• Plain finish suitable for dry and controlled-environment installations
• Inch-system dimensioning for straightforward spec matching

Compatibility

Designed as a standard inch-series slotted spring pin for general commercial mechanical assemblies requiring a 0.125 inch diameter pin in a 0.375 inch bore depth.

Installation Notes

Slotted spring pins are typically installed by maintenance technicians or mechanical assemblers using a pin punch and hammer or a press. Ensure the receiving bore is clean and within the manufacturer-specified tolerance before driving the pin. Always de-energize and lock out any machinery before servicing components that contain these pins. Do not reuse pins that have been removed, as the slotted body may not retain its original tension after extraction.
