Value Collection R57700705 Slotted Spring Pin 0.125in Alloy Steel

Product Description

The VALUE COLLECTION R57700705 is a slotted spring pin designed for use in mechanical assemblies where a reliable, removable fastener is needed to secure components along a shaft or through a bore. Measuring 0.125 inches in diameter and 7/16 inches in overall length, this pin is manufactured from 1070-1090 grade alloy steel with a plain finish. The slotted design allows the pin to compress on insertion and expand against the bore wall, creating a firm, vibration-resistant hold without requiring adhesive or additional hardware. Machinists, millwrights, and maintenance technicians are the typical installers for this type of fastener.

This slotted spring pin is suited for general industrial and mechanical applications including shaft-to-hub connections, linkage assemblies, and component alignment tasks across light to medium-duty machinery. Its small diameter and compact length make it appropriate for precision assemblies where space is limited. The plain finish indicates no additional corrosion-protective coating, so it is best applied in dry or protected environments.

Key Features

• Slotted design compresses on insertion for a secure, self-retaining fit in the bore
• 0.125 inches (1/8 inch) pin diameter for small-bore applications
• 7/16 inches overall length suits compact mechanical assemblies
• 1070-1090 grade alloy steel construction provides adequate strength for general mechanical use
• Plain finish keeps installation straightforward in protected or dry environments
• Inch measurement system for compatibility with standard imperial tooling

Compatibility

Designed as a general-purpose slotted spring pin for standard imperial mechanical assemblies requiring a 0.125 inch bore diameter. Does not meet military specifications.

Installation Notes

Slotted spring pins are installed by machinists or maintenance technicians using a pin punch and hammer or a hydraulic press, depending on the assembly. Always de-energize and lock out machinery before pin removal or insertion. Ensure the bore diameter matches the pin diameter to prevent damage to the bore wall or the pin during installation. Do not use an oversized driver that contacts the bore edge instead of the pin head.
