Value Collection R57700557 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700557 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. This design creates a spring-loaded grip inside a drilled hole, securing shafts, linkages, clevis assemblies, and other mechanical components against rotation or axial movement. At 0.75 inches in overall length and 7/32 inch in diameter, this pin suits light- to medium-duty mechanical assemblies across HVAC equipment, plumbing hardware, pump linkages, and general industrial applications. Maintenance technicians, millwrights, and trade professionals install these pins as both OEM replacements and new assembly fasteners.

This slotted spring pin is suited for use in mechanical sub-assemblies where a press-fit, self-retaining fastener is required. The 18-8 stainless steel construction provides corrosion resistance in wet or humid environments, making it appropriate for plumbing fixtures, pump housings, pool equipment linkages, and HVAC component assemblies exposed to moisture. The inch-measurement dimensions are compatible with standard inch-series drilled holes. This pin does not meet military specifications and is intended for commercial and industrial service applications.

Key Features

• Slotted design allows radial compression for a secure, self-retaining press fit in drilled holes
• 18-8 stainless steel construction resists corrosion in wet, humid, and mildly chemical environments
• 0.75 inch overall length suits compact mechanical linkage and shaft retention applications
• 7/32 inch diameter fits standard inch-series drilled holes
• Reusable fastener design allows removal and reinstallation with appropriate drift punch tooling

Compatibility

Designed as a general-purpose commercial replacement slotted spring pin for inch-series mechanical assemblies requiring a 7/32 inch diameter roll pin in a 0.75 inch engagement length.

Installation Notes

Slotted spring pins are installed by mechanical technicians using a drift punch or pin driver sized to match the pin diameter. The receiving hole should be drilled to the appropriate tolerance for the pin diameter before installation. Always de-energize and lock out any equipment before servicing components that retain this pin. Removal is performed by driving the pin through the hole from the opposite side using a punch and hammer.
