Value Collection R57700515 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700515 is a slotted spring pin manufactured from 18-8 stainless steel. Spring pins, also called roll pins or tension pins, are hollow cylindrical fasteners with a longitudinal slot that allows radial compression during installation. The pin exerts outward spring force against the hole wall, creating a secure, vibration-resistant connection without threads or adhesive. At 9/16 inches in overall length and 3/16 inches in diameter, this pin is suited for light- to medium-duty assemblies where corrosion resistance is a requirement. Maintenance technicians, millwrights, and mechanical contractors install these in equipment where standard carbon steel fasteners would corrode.

Slotted spring pins in 18-8 stainless steel are commonly used in HVAC equipment panels, plumbing valve assemblies, pump housings, and pool equipment linkages where moisture or chemical exposure rules out plain steel. They are installed in drilled through-holes or blind holes and are driven with a pin punch and hammer or an arbor press. This part is sold individually as a single-piece package quantity, with a minimum order quantity of 100 units, making it practical for stocking service vans or shop bins.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet or chemically active environments
• Slotted design compresses radially on installation for a secure, self-retaining fit
• 9/16 inches overall length suits compact mechanical assemblies
• 3/16 inches diameter for standard drilled hole fitment
• No threads required — driven installation with standard punch or arbor press
• Inch measurement system for compatibility with standard US tooling and gauges

Compatibility

Designed as an OEM-style replacement or service stock slotted spring pin for mechanical assemblies requiring a 3/16 inches diameter, 9/16 inches long pin in an inch-measurement system.

Installation Notes

Slotted spring pins are installed by mechanical technicians and millwrights using a pin punch sized to the pin diameter and a hammer, or an arbor press for precision work. Always de-energize and lock out equipment before driving or removing pins from live assemblies. Verify hole diameter matches the nominal pin diameter to ensure proper spring retention. Avoid reusing spring pins that have been fully compressed, as the material may have yielded and the retaining force will be reduced.
