Value Collection R63098643 Slotted Spring Pin 4 in 420 Ss

Product Description

The VALUE COLLECTION R63098643 is a slotted spring pin designed for secure fastening in assemblies that require a resilient, press-fit retention solution. Manufactured from Grade 420 stainless steel with a bright finish, this pin measures 4 inches in overall length and 3/8 inch in diameter. The slotted construction allows the pin to compress on insertion and exert outward radial force against the bore wall, creating a firm, vibration-resistant fit without the need for adhesives or additional hardware. Machinists, millwrights, and maintenance technicians install slotted spring pins in a wide range of industrial and mechanical assemblies.

This pin is suited for use in both light and heavy-duty mechanical assemblies where corrosion resistance and dimensional consistency are required. Grade 420 stainless steel provides moderate corrosion resistance and higher hardness compared to austenitic grades, making it appropriate for environments where wear resistance matters alongside oxidation protection. Typical applications include shaft-to-hub connections, linkage assemblies, and hinge pivot points in industrial machinery, agricultural equipment, and general fabrication work.

Key Features

• Grade 420 stainless steel construction for corrosion resistance and increased hardness
• Slotted design compresses on insertion for a secure, vibration-resistant press fit
• 4 inches overall length with 3/8 inch diameter for medium-duty fastening applications
• Bright finish for consistent surface quality and dimensional accuracy
• Inch measurement system for compatibility with standard imperial bore sizing

Compatibility

Designed as an OEM-style replacement or direct-fit slotted spring pin for imperial-dimensioned bores requiring a 3/8 inch diameter pin in industrial, agricultural, and general mechanical assemblies.

Installation Notes

Slotted spring pins are typically installed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. The receiving bore should be inspected for burrs and sized to the appropriate tolerance before installation. Always support the workpiece to prevent distortion during driving. Removal is performed with a punch sized to clear the slot, driving the pin out from the closed end when possible.
