Value Collection R57700703 Slotted Spring Pin Alloy Steel

Product Description

The VALUE COLLECTION R57700703 is a slotted spring pin designed for use in mechanical assemblies requiring a reliable, press-fit fastening solution. Manufactured from 1070-1090 alloy steel with a plain finish, this pin measures 0.125 inches in diameter and 5/16 inches in overall length. Slotted spring pins compress radially during installation and exert constant outward pressure against the host bore, creating a secure, vibration-resistant fit without the need for adhesives or locking hardware. Machinists, millwrights, and assembly technicians install these pins in production and maintenance environments across a wide range of industrial applications.

This pin is suited for use in light-duty to medium-duty mechanical assemblies where a standard inch-series slotted pin is specified. Typical applications include shaft-to-hub connections, hinge pivots, gear and pulley retention, and fixture alignment. The compact 0.125-inch diameter and 5/16-inch length make it appropriate for smaller components and tight clearance installations. The plain finish is adequate for most indoor and protected mechanical environments where corrosion exposure is minimal.

Key Features

• Slotted design allows radial compression for press-fit installation into standard toleranced bores
• 1070-1090 alloy steel construction provides strength suitable for light-duty to medium-duty mechanical loads
• Plain finish offers a clean surface profile compatible with most standard bore fits
• Inch-series dimensions: 0.125 inches diameter and 5/16 inches overall length
• Does not meet military specifications — intended for commercial and industrial applications

Compatibility

Designed as a standard inch-series slotted spring pin for use in mechanical assemblies specifying a 0.125-inch nominal bore diameter and 5/16-inch pin length.

Installation Notes

Slotted spring pins are typically installed by machinists or assembly technicians using a pin punch and hammer or an arbor press. Ensure the receiving bore is clean, free of burrs, and machined to the appropriate toleranced diameter before installation. Do not exceed the designed bore depth to avoid overdriving and distorting the pin. When removing pins, use the appropriate punch size to prevent bore damage.
