Value Collection R57700445 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700445 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also called roll pins, use a longitudinal slot that allows the pin to compress during installation and exert radial spring force against the bore wall, creating a secure interference fit without adhesives or locking hardware. This pin measures 7/16 inch in overall length and 1/8 inch in diameter. The 18-8 stainless steel construction provides corrosion resistance suitable for wet, chemical-exposure, or food-adjacent environments. Mechanical assemblers, maintenance technicians, and fabricators install these pins to align, retain, or pivot components across a wide range of industrial and mechanical assemblies.

This slotted spring pin is used in light-duty to medium-duty mechanical assemblies where a removable, reusable fastener is preferred over a solid dowel pin. Typical applications include shaft-to-hub alignment, hinge pivots, clevis connections, and component retention in machinery, fixtures, and equipment. The small diameter and short length suit compact assemblies with tight space constraints. The stainless steel grade makes it appropriate for marine hardware, plumbing assemblies, food processing equipment, and other corrosion-sensitive environments.

Key Features

• Slotted design compresses on installation for a self-retaining interference fit
• 18-8 stainless steel construction resists corrosion in wet and chemical environments
• 1/8 inch diameter suits compact bore applications
• 7/16 inch overall length for short-retention assemblies
• Reusable and removable without damaging the host bore in most applications

Compatibility

Designed as a standard slotted spring pin for use in any application requiring a 1/8 inch diameter, 7/16 inch long roll pin in an inch-measurement system. Note: this pin does not meet military specifications.

Installation Notes

Installation typically requires a pin punch sized to match the pin diameter and a hammer or arbor press to drive the pin flush or to the desired depth. Always de-energize, depressurize, or lock out the assembly before installing or removing spring pins. Avoid reusing heavily deformed pins as the slot may not provide adequate spring force after repeated compression cycles.
