Value Collection R57700555 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700555 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also called roll pins, use a longitudinal slot to allow radial compression during installation, creating a secure interference fit in the mating hole. This pin measures 5/8 inches in overall length with a 7/32 inch diameter. The 18-8 stainless steel construction provides good corrosion resistance and moderate strength, making it suitable for applications where exposure to moisture or mild chemicals is a factor. Maintenance technicians, millwrights, and assembly professionals install these fasteners in mechanical assemblies, linkages, and pivot points across HVAC, plumbing, and industrial equipment.

This slotted spring pin is used in light-duty to medium-duty mechanical assemblies where a removable or semi-permanent cylindrical fastener is required. Typical applications include hinge pins, shaft-to-collar connections, clevis assemblies, and control linkages found in HVAC equipment, pumps, valves, and general mechanical hardware. The inch-system dimensions suit standard North American bore sizes. This item is sold individually but carries a minimum order quantity of 100 units, making it appropriate for shop stock, MRO inventory, or production assembly use.

Key Features

• 18-8 stainless steel construction offers corrosion resistance in wet or mildly corrosive environments
• Slotted design allows radial compression for secure interference fit without adhesives or secondary fasteners
• 5/8 inch overall length suits compact mechanical linkage and pivot applications
• 7/32 inch diameter fits standard inch-system bores
• Inch measurement system for direct compatibility with standard North American tooling and gauges

Compatibility

Designed as a standard inch-system slotted spring pin suitable for mechanical assemblies requiring a 7/32 inch diameter roll pin in a 5/8 inch length.

Installation Notes

Slotted spring pins are installed by maintenance technicians and assembly professionals using a pin punch and hammer or an arbor press. Always de-energize and lock out the equipment before servicing any mechanical assembly containing these fasteners. Ensure the receiving bore is clean, free of burrs, and sized within the recommended tolerance for the pin diameter before driving the pin into position. Do not reuse a pin that has been fully collapsed or deformed, as the spring characteristic may be compromised.
