Value Collection R57700129 Slotted Spring Pin Alloy Steel

Product Description

The VALUE COLLECTION R57700129 is a slotted spring pin designed for use in mechanical assemblies requiring a secure, removable fastener that can flex under load. The slotted design allows the pin to compress during installation and expand against the bore wall, creating a firm interference fit without the need for adhesives or secondary locking hardware. Manufactured from 1070-1090 alloy steel with a plain finish, this pin measures 0.0625 inches in diameter and 1 inch in overall length. It is installed by maintenance technicians and mechanical assemblers in light to medium-duty applications where controlled retention force is required.

This pin is suited for use in machine components, brackets, linkages, and mechanical sub-assemblies where a standard inch-series slotted spring pin is called for. Its 1/16 inch fractional diameter and 1 inch length make it compatible with tight-tolerance bores in metal and engineered plastic housings. It is commonly used in production environments and repair applications across industrial, agricultural, and general mechanical trades.

Key Features

• Slotted spring design compresses during installation for a secure interference fit
• 0.0625 inch (1/16 inch) diameter with 1 inch overall length in inch-series sizing
• 1070-1090 alloy steel construction provides good tensile strength and fatigue resistance
• Plain finish suitable for dry or lightly lubricated environments
• Inch system of measurement for compatibility with standard imperial bore specifications

Compatibility

Designed as a standard inch-series slotted spring pin for use in mechanical assemblies and components requiring a 0.0625 inch diameter bore fastener per inch-system specifications.

Installation Notes

Slotted spring pins are typically installed using a pin punch and hammer or an arbor press — avoid impact tools that may distort the pin slot or damage the receiving bore. Ensure the bore diameter is within tolerance for the specified pin size before driving. Always de-energize and lock out any machinery before servicing components that contain spring pins. Pins should be replaced rather than reused if removal required significant force, as the slot geometry may have been compromised.
