Value Collection R57900555 Slotted Spring Pin 26mm 2.5mm

Product Description

The VALUE COLLECTION R57900555 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins are cylindrical fasteners with a longitudinal slot that allows the pin to compress during installation, then exert outward radial pressure against the hole wall to resist loosening and absorb shock loads. This pin measures 26 mm in length and 2.5 mm in diameter. It is a metric-dimensioned component suited for general mechanical assembly work across industrial, maintenance, and manufacturing applications. Installation is typically performed by mechanical assemblers and maintenance technicians using a pin punch and hammer or an arbor press.

This slotted spring pin is designed for use in metric-dimensioned assemblies where a press-fit, self-retaining fastener is required. Common applications include securing gears, levers, knobs, and linkages to shafts, as well as alignment and locking duties in light-duty machinery and fixtures. The plain finish makes it suitable for dry or lightly lubricated interior environments where corrosion resistance is not a primary requirement. This part is sold individually per unit.

Key Features

• Slotted design allows radial compression during installation for a secure interference fit
• 1070-1080 grade carbon steel provides good hardness and fatigue resistance for spring pin duty
• 26 mm overall length in metric sizing for international and metric-standard assemblies
• 2.5 mm diameter for use in correspondingly sized metric bores
• Plain finish suited for controlled-environment or internally located fastener applications
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed as a standard metric slotted spring pin for use in general commercial and industrial mechanical assemblies requiring a 2.5 mm diameter, 26 mm long spring pin. No specific OEM model compatibility was stated by the manufacturer for this part number.

Installation Notes

Slotted spring pins should be installed using a properly sized pin punch and hammer or an arbor press to avoid deforming the pin or damaging the bore. Ensure the receiving hole is cleanly drilled or reamed to the correct diameter before driving the pin. Always de-energize and lock out any equipment before performing fastener installation or removal. Remove and inspect spring pins that show cracking, deformation, or corrosion rather than reusing them.
