Value Collection R57700639 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700639 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also called roll pins, are cylindrical fasteners with a lengthwise slot that allows the pin to compress slightly during installation, creating a secure interference fit in a drilled hole. This pin measures 3-1/2 inches in length with a 5/16 inch diameter. The 18-8 stainless steel construction provides good corrosion resistance and adequate strength for a wide range of industrial, mechanical, and trade applications. Maintenance technicians, millwrights, plumbers, and HVAC technicians use slotted spring pins to secure linkages, retain shafts, and align components in assemblies.

This slotted spring pin is suited for use in residential and light commercial mechanical assemblies where a reliable, removable, and corrosion-resistant fastener is required. Typical applications include securing pivot arms, aligning flanges, retaining clevis pins, and anchoring hinge linkages in HVAC equipment, pump assemblies, valve actuators, and piping systems. The stainless steel grade makes it appropriate for wet or humid environments where carbon steel fasteners would corrode. Sold individually, with a minimum order quantity of 5 units.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and humid environments
• 3-1/2 inch overall length suits medium-depth through-hole fastening applications
• 5/16 inch diameter provides a solid interference fit in standard drilled holes
• Slotted design allows radial compression during installation without special tooling
• Reusable and removable with standard pin punches and a hammer

Compatibility

Designed as a standard slotted spring pin for use in any mechanical assembly requiring a 5/16 inch diameter, 3-1/2 inch long roll pin with an inch-system fit.

Installation Notes

Installation is performed using a pin punch sized to the pin diameter and a hammer or arbor press. Ensure the receiving hole is drilled to the correct diameter for a proper interference fit before driving the pin. De-energize or lock out any equipment before installing or removing spring pins in powered assemblies. Removal is accomplished by driving the pin out from the opposite end using a punch of matching or slightly smaller diameter.
