Value Collection R57700221 Slotted Spring Pin 0.25 in 3 in

Product Description

The VALUE COLLECTION R57700221 is a slotted spring pin designed for use in mechanical assemblies requiring a secure, removable fastening solution. Measuring 0.25 inches in diameter and 3 inches in length, this pin is manufactured from 1070-1090 alloy steel with a plain finish. The slotted design allows the pin to compress during installation and exert outward spring force against the bore wall, creating a firm, vibration-resistant fit. Machinists, maintenance technicians, and industrial assemblers install this type of pin in shafts, linkages, and machine components where frequent disassembly is not required.

This slotted spring pin is suited for use in general industrial and mechanical applications. It is commonly installed in shaft-to-hub connections, clevis joints, linkage assemblies, and fixture components across manufacturing, agricultural equipment, and industrial machinery. The 1070-1090 alloy steel construction provides the strength and elasticity characteristics expected of standard-duty spring pins in inch-measurement systems. This part does not meet military specifications and is intended for commercial and industrial use.

Key Features

• Slotted design compresses on installation to create a spring-loaded interference fit in the bore
• 0.25 inch diameter fits standard quarter-inch bored holes in shafts and linkages
• 3 inch overall length accommodates deeper assemblies and through-pin applications
• 1070-1090 alloy steel provides the elasticity and shear strength required for spring pin duty
• Plain finish with no coating — suitable for use in dry or lightly lubricated environments
• Inch measurement system sizing for compatibility with standard US machine tooling

Compatibility

Designed as a standard-duty slotted spring pin for use in commercial and industrial mechanical assemblies requiring a 0.25 inch diameter, 3 inch long inch-system pin. No specific model or system compatibility data was provided for this part.

Installation Notes

Slotted spring pins are typically installed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. Ensure the receiving bore is clean and free of debris before pressing the pin into place. The pin should be driven flush or to the required depth without exceeding the bore depth or distorting the surrounding material. Removal is performed by driving the pin out from one end with an appropriately sized punch.
