Value Collection R57900621 Slotted Spring Pin 26mm 3.5mm

Product Description

The VALUE COLLECTION R57900621 is a metric slotted spring pin manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins are cylindrical fasteners with a lengthwise slot that allows radial compression during installation, enabling them to seat firmly in drilled holes and resist vibration-induced loosening. This pin measures 26 mm in overall length and 3.50 mm in diameter, making it suited for light- to medium-duty fastening applications in mechanical assemblies. Machinists, millwrights, and maintenance technicians install this type of hardware when a removable, self-retaining pin is needed to align or retain mating components.

This slotted spring pin is used in a wide range of mechanical and industrial applications where metric fasteners are specified. Typical installations include machine frames, linkage assemblies, hinges, shafts, and brackets where a compressible retention pin is preferred over a solid dowel. The metric sizing makes it appropriate for equipment built to metric engineering standards. It is not designed or rated to meet military specifications.

Key Features

• 1070-1080 grade steel construction provides reliable strength for general mechanical fastening
• Slotted design allows radial compression for secure press-fit installation without adhesives
• Plain finish suitable for indoor mechanical assemblies with standard environmental exposure
• Metric dimensions: 26 mm overall length and 3.50 mm diameter
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed as a metric slotted spring pin for general commercial and industrial mechanical assemblies requiring a 3.50 mm diameter, 26 mm long compressible retention fastener.

Installation Notes

Slotted spring pins are typically installed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. The receiving hole should be sized to the nominal pin diameter per standard engineering tolerances to achieve proper retention. Always de-energize and lock out any machinery before servicing pin-retained components. Avoid reusing a heavily deformed pin, as repeated compression cycles can compromise retention force.
