Value Collection R57700391 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700391 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also called roll pins, are hollow cylindrical fasteners with a lengthwise slot that allows the pin to compress on insertion and exert a constant outward spring force against the bore wall. This design creates a secure, vibration-resistant fit without requiring adhesive or secondary locking hardware. The R57700391 measures 5/8 inches in overall length with a 5/64 inch diameter. At 0.01 pounds per unit, it is a lightweight fastener suited for precision assemblies where corrosion resistance and reliable retention are required.

This slotted spring pin is used in mechanical assemblies across a range of industries including HVAC equipment manufacturing, plumbing component fabrication, and general industrial applications. Common installation scenarios include securing levers, collars, gears, and linkages to shafts, as well as alignment and retention duties in light-duty equipment. The 18-8 stainless steel construction makes it appropriate for environments with moisture exposure or mild chemical contact where carbon steel fasteners would corrode prematurely.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet or chemically active environments
• Slotted design compresses on insertion for a self-retaining, vibration-resistant fit
• 5/8 inch overall length suitable for thin-section and compact assemblies
• 5/64 inch diameter for use in small-bore precision applications
• Inch measurement system for straightforward compatibility with standard tooling

Compatibility

Designed as a standard-dimension slotted spring pin for use in any mechanical assembly requiring a 5/64 inch bore diameter and 5/8 inch pin length in inch-series fastener applications.

Installation Notes

Slotted spring pins are typically installed by maintenance technicians and mechanical assemblers using a pin punch and hammer or an arbor press. Ensure the receiving bore is clean and free of burrs before driving the pin to avoid deforming the slot or splitting the pin body. Never reuse a slotted spring pin that has been removed, as repeated compression cycles can fatigue the material and reduce retention force.
