Value Collection R57700629 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700629 is a slotted spring pin manufactured from 18-8 stainless steel, designed to secure components by exerting radial pressure within a drilled hole. The slotted design allows the pin to compress during insertion and expand to grip the bore walls, providing a reliable, vibration-resistant connection without adhesives or fasteners. At 1-3/4 inches in overall length and 5/16 inch in diameter, this pin suits a range of light-to-medium-duty mechanical assemblies. Machinists, maintenance technicians, and industrial assembly professionals typically install these as alignment, retention, or hinge pins in fabricated assemblies and machinery.

This slotted spring pin is suited for use in mechanical assemblies where corrosion resistance is a priority, such as food-processing equipment, marine hardware, plumbing fixtures, and outdoor machinery. The 18-8 stainless steel grade offers good resistance to rust and mild chemical exposure. It is well-suited for applications requiring a removable, reusable fastener in sheet metal, castings, or machined components where a precisely drilled hole is present.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet or mildly corrosive environments
• Slotted design allows radial compression for secure press-fit retention in drilled bores
• Overall length of 1-3/4 inches suits a variety of standard mechanical assembly depths
• 5/16 inch diameter fits standard drilled or reamed hole patterns
• Inch measurement system for compatibility with standard imperial tooling and print dimensions
• Does not meet military specifications — intended for commercial and industrial applications

Compatibility

Designed as a standard slotted spring pin for use in commercial and industrial mechanical assemblies requiring a 5/16 inch bore and 1-3/4 inch pin length in an imperial measurement system.

Installation Notes

Slotted spring pins are installed by pressing or driving the pin into a drilled hole of the appropriate diameter using a pin punch and hammer or a hydraulic press. Always de-energize and lock out any machinery before installing or removing retaining pins. Ensure the bore is clean, free of burrs, and sized to the correct tolerance for a proper interference fit. Use of oversized or undersized holes may result in insufficient retention or damage to the pin.
