Value Collection R57700521 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700521 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also called roll pins, are hollow cylindrical fasteners with a longitudinal slot that allows the pin to compress during insertion and exert radial pressure against the bore wall, creating a secure, vibration-resistant fit without adhesives or additional hardware. This pin measures 3/4 inches in length and 3/16 inches in diameter. It is installed by machinists, maintenance technicians, and assembly professionals working with light to medium-duty mechanical assemblies where corrosion resistance and reliable retention are required.

This slotted spring pin is suited for use in mechanical linkages, hinges, clevis assemblies, and shaft-to-hub connections where moderate shear loads are present. The 18-8 stainless steel construction makes it appropriate for environments exposed to moisture, mild chemicals, or food-adjacent conditions where carbon steel fasteners would corrode. Typical applications include general industrial machinery, instrumentation, and light fabrication work. This item is sold individually, with a minimum order quantity of 100 units.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet or mildly corrosive environments
• Slotted design allows radial compression during installation for a secure interference fit
• 3/4 inches overall length and 3/16 inches diameter suit a wide range of standard bore applications
• Does not require adhesive, threading, or secondary locking hardware
• Inch measurement system; UNSPSC Code 31163201

Compatibility

Designed as a standard slotted spring pin for use in any application requiring a 3/16 inches diameter, 3/4 inches long roll pin in an inch-dimensioned assembly.

Installation Notes

Slotted spring pins are installed using a pin punch and hammer or a hydraulic press; select a punch tip sized to fit inside the pin bore without contacting the slot edges. Always de-energize and lock out any machine before removing or installing drive pins in rotating assemblies. Ensure the receiving bore diameter is within the recommended tolerance range for a 3/16 inches spring pin before pressing to avoid deforming the pin or damaging the workpiece. Do not reuse a spring pin that has been fully compressed or shows visible cracking along the slot.
