Value Collection R57700215 Slotted Spring Pin 0.25in Alloy Steel

Product Description

The Value Collection R57700215 is a slotted spring pin manufactured from 1070-1090 alloy steel with a plain finish. Slotted spring pins, also called slotted roll pins, feature a longitudinal slot that allows the pin to compress radially during installation, creating a secure interference fit within the host material. This pin measures 0.25 inches in diameter and 2.25 inches in overall length. It is used in mechanical assemblies to locate, retain, or align mating components. Installation is typically performed by machinists, millwrights, or maintenance technicians working on precision assemblies, machinery, and structural hardware applications.

This slotted spring pin is suited for use in general industrial and mechanical assembly applications where a removable or semi-permanent retention pin is required. The 1070-1090 alloy steel construction provides strength appropriate for moderate load and shear applications. The plain finish makes it compatible with environments where additional corrosion protection will be applied to the assembly or where exposure to moisture and chemicals is minimal. It does not meet military specifications.

Key Features

• Slotted design allows radial compression for secure interference fit installation
• 1070-1090 alloy steel construction for reliable shear and load strength
• Plain finish suitable for standard industrial assembly use
• 0.25 inch diameter with 2.25 inch overall length for a range of through-hole applications
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed as a standard inch-series slotted spring pin for general mechanical assembly applications where a 0.25 inch diameter roll pin is specified.

Installation Notes

Slotted spring pins are typically installed using a pin punch and hammer or an arbor press to drive the pin into a drilled hole sized to produce the required interference fit. Always ensure the receiving hole diameter and depth are within specification before driving the pin. Avoid over-driving, which can damage the host material or deform the pin beyond its designed compression range. Removal requires a punch of appropriate diameter driven from the accessible end of the pin.
