Value Collection R57900551 Slotted Spring Pin 22mm

Product Description

The VALUE COLLECTION R57900551 is a slotted spring pin designed for use in mechanical assemblies where controlled radial pressure is needed to secure shafts, housings, and cylindrical components. The pin measures 22 mm in length with a 2.5 mm diameter and is manufactured from 1070-1080 grade carbon steel with a plain finish. Its slotted design allows the pin to compress on insertion and expand to exert outward force against the bore wall, creating a firm, vibration-resistant fit without adhesives or secondary fasteners. Machinists, maintenance technicians, and assembly professionals install these pins across a wide range of industrial and mechanical applications.

This slotted spring pin is suited for use in light- to medium-duty mechanical assemblies including gear and shaft connections, hinge pivots, locking mechanisms, and general fastening applications. The metric sizing makes it appropriate for equipment built to metric standards. The plain steel finish is suitable for interior or protected environments where corrosion exposure is limited. These pins are sold individually per package, with a minimum order quantity of 100 units.

Key Features

• Slotted design compresses on insertion for a secure interference fit in the bore
• 22 mm overall length in metric sizing for metric-standard assemblies
• 2.5 mm diameter for use in close-tolerance bored holes
• 1070-1080 grade carbon steel construction for strength and durability
• Plain finish suitable for dry or protected indoor mechanical environments
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed as a standard metric slotted spring pin for general mechanical assembly applications requiring a 2.5 mm diameter, 22 mm long coiled or slotted fastener in bored holes built to metric tolerances.

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 bore is clean, properly sized, and free of burrs before driving the pin. Always wear appropriate eye protection during installation. Pins should be driven straight and flush or to the required depth without bending or deforming the slotted body.
