Value Collection R57700471 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700471 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also known as roll pins, are hollow, cylindrical fasteners with a longitudinal slot that allows the pin to compress during insertion and exert a constant outward spring force against the bore wall. This self-retaining design eliminates the need for additional locking hardware. The R57700471 measures 1-7/8 inches in length and 1/8 inch in diameter. It is installed by machinists, millwrights, and maintenance technicians working on assemblies that require a removable, vibration-resistant pin connection.

This slotted spring pin is suited for use in light to medium-duty mechanical assemblies including linkages, hinges, clevis connections, and pivot joints across industrial, agricultural, and general equipment applications. The 18-8 stainless steel construction makes it appropriate for environments where mild corrosion resistance is required. This part is sold individually but carries a minimum order quantity of 100 units, making it well suited for shop-stock replenishment or production assembly operations.

Key Features

• Slotted design provides radial spring force for self-retaining installation without secondary locking fasteners
• 18-8 stainless steel construction offers good corrosion resistance in mild service environments
• 1/8 inch diameter and 1-7/8 inch length suit a range of standard bore applications
• Inch system dimensioning for compatibility with standard fractional tooling and bore gauges
• Does not meet military specifications — intended for commercial and industrial service

Compatibility

Designed as a standard slotted spring pin for use in commercial and industrial mechanical assemblies requiring a 1/8 inch diameter bore and approximately 1-7/8 inch pin engagement length.

Installation Notes

Slotted spring pins are typically installed using a pin punch and hammer or an arbor press; never drive spring pins with impact tools that could deform the slot geometry. Ensure the receiving bore diameter matches the nominal pin diameter per applicable ASME or ISO standards before installation. Power down or de-energize any equipment and relieve all mechanical loads before removing or installing pins in live assemblies. Removal is accomplished by driving or pressing the pin out from the accessible end using an appropriate punch.
