Value Collection R63094321 Slotted Spring Pin 420 Ss

Product Description

The VALUE COLLECTION R63094321 is a slotted spring pin manufactured from 420 stainless steel with a bright finish. Slotted spring pins, also called roll pins, are hollow cylindrical fasteners with a longitudinal slot that allows the pin to compress during installation and exert a constant outward spring force against the hole wall. This design creates a secure, vibration-resistant fit without adhesives or secondary locking hardware. At 0.25 inches in overall length and 3/32 inches in diameter, this pin is suited for light-duty fastening, alignment, and hinge applications in compact assemblies. Machinists, maintenance technicians, and assembly workers are the typical installers.

This slotted spring pin is used in mechanical assemblies requiring a reliable, reusable fastener in a small form factor. The 420 stainless steel construction provides moderate corrosion resistance and good hardness, making it appropriate for general industrial, marine-adjacent, and light-duty machine applications where carbon steel would be unsuitable. The bright finish indicates a clean, non-coated surface condition. This pin does not meet military specifications and is sold in a minimum order quantity of 100 pieces per order.

Key Features

• 420 stainless steel construction provides moderate corrosion resistance and elevated hardness compared to austenitic grades
• Bright finish for a clean, non-coated surface suitable for precision fits
• Slotted design allows radial compression during installation for a self-retaining, vibration-resistant fit
• Compact 0.25 inch length and 3/32 inch diameter for use in tight or miniature assemblies
• Inch measurement system for compatibility with standard inch-dimensioned tooling and gauges

Compatibility

Designed as a standard slotted spring pin for use in inch-dimensioned assemblies requiring a 3/32 inch diameter roll pin hole and a 0.25 inch pin length. No specific OEM equipment compatibility is stated by the manufacturer 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 hole is drilled and reamed to the correct diameter before installation to avoid damaging the pin or the workpiece. Align the pin slot away from the primary load direction where possible to maximize shear strength. Always wear appropriate eye protection when driving pins manually.
