Value Collection R57700327 Slotted Spring Pin Alloy Steel

Product Description

The VALUE COLLECTION R57700327 is a slotted spring pin designed for use in mechanical assemblies requiring a reliable, interference-fit fastener. Measuring 3/8 inch in length and 1/16 inch in diameter, this pin is manufactured from 1070-1090 alloy steel with a plain finish. The slotted design allows the pin to compress on insertion and exert radial force against the bore wall, providing a secure hold without adhesives or threading. It is installed by machinists, maintenance technicians, and assembly professionals across a wide range of industrial and mechanical applications.

This slotted spring pin is suited for light-duty to medium-duty mechanical assemblies where a small-diameter, short-length retention pin is required. Common applications include shaft-to-hub connections, pivot points, and alignment fixtures in equipment manufacturing, tool and die work, and general machine assembly. The plain finish is appropriate for interior or protected installations where corrosion exposure is minimal.

Key Features

• Slotted design compresses on insertion for a secure interference fit
• 1070-1090 alloy steel construction provides reliable strength for small fastener applications
• Plain finish suitable for protected interior assembly use
• Inch measurement system, 3/8 inch length by 1/16 inch diameter
• Does not meet military specifications

Compatibility

Designed as a standard slotted spring pin for use in mechanical assemblies requiring a 1/16 inch diameter, 3/8 inch long retention pin in inch-measurement applications.

Installation Notes

Slotted spring pins are typically installed using a pin punch and hammer or an arbor press. Ensure the receiving bore diameter matches the pin specification to achieve proper interference fit. Inspect the bore for burrs or damage before installation. Do not reuse a spring pin that has been removed, as the slotted body may fatigue and lose clamping force.
