Value Collection R57700659 Slotted Spring Pin 4in 3/8in

Product Description

The VALUE COLLECTION R57700659 is a slotted spring pin manufactured from 18-8 stainless steel, designed to secure components by compressing during insertion and exerting radial pressure within a drilled hole. At 4 inches in overall length and 3/8 inch in diameter, this pin provides reliable retention in mechanical assemblies where vibration resistance and corrosion resistance are priorities. The slotted design allows the pin to flex, distributing load across the slot and reducing stress concentrations. It is installed by maintenance technicians, millwrights, and mechanical assemblers across industrial, marine, and general manufacturing applications.

This slotted spring pin is suited for use in shafts, linkages, hinges, and other mechanical connections requiring a removable or semi-permanent retention fastener. The 18-8 stainless steel construction makes it appropriate for environments with moisture exposure or mild corrosive conditions. It is a standard inch-system fastener compatible with drilled-hole assemblies calling for a 3/8 inch pin diameter and 4 inch length. This part does not meet military specifications.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet or mildly corrosive environments
• Slotted design allows radial compression for secure press-fit retention
• 4 inches overall length suits deeper shaft and linkage applications
• 3/8 inch diameter for standard drilled-hole fitment
• Inch-system dimensions for compatibility with standard imperial-spec assemblies

Compatibility

Designed as a standard inch-system slotted spring pin for mechanical assemblies requiring a 3/8 inch diameter, 4 inch long retention fastener in drilled-hole applications.

Installation Notes

Slotted spring pins are typically installed by millwrights, mechanical assemblers, or maintenance technicians using a pin punch and hammer or an arbor press. De-energize and lock out all equipment before pin removal or installation. Ensure the receiving hole diameter matches the nominal pin diameter to achieve proper interference fit. Do not reuse a pin that shows deformation, cracking along the slot, or corrosion damage.
