Value Collection R57900623 Slotted Spring Pin 28mm

Product Description

The VALUE COLLECTION R57900623 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins are radially slotted along their length, allowing the pin to compress during insertion and exert a constant outward spring force against the host bore. This design provides secure retention without permanent deformation of the mating component. The R57900623 measures 28 mm in overall length with a 3.50 mm diameter. It is a metric-dimensioned fastener intended for use in mechanical assemblies where a removable, self-retaining pin is required. Installation is performed by mechanical or industrial assembly technicians using standard press or hammer-drive tooling.

This slotted spring pin is suited for use in precision mechanical assemblies, industrial equipment, and general-purpose machine components requiring a metric pin fastener. The 3.50 mm diameter and 28 mm length make it appropriate for moderate-load retention applications in shafts, linkages, clevis connections, and similar assemblies. This part does not meet military specifications and is intended for commercial and industrial use. It is sold individually per package, with a minimum order quantity of 100 pieces.

Key Features

• Slotted design allows radial compression for secure self-retaining fit in the bore
• 1070-1080 carbon steel construction provides good hardness and shear strength
• Plain finish suitable for protected or indoor mechanical environments
• Metric dimensioning: 28 mm length, 3.50 mm diameter
• Commercial-grade fastener for general industrial and mechanical assembly use

Compatibility

Designed as a metric slotted spring pin for general commercial and industrial mechanical assemblies requiring a 3.50 mm diameter, 28 mm long pin fastener. Verify bore diameter and length requirements against assembly drawings before installation.

Installation Notes

Slotted spring pins are installed by mechanical assembly technicians using a pin punch and hammer or an arbor press. Ensure the receiving bore is clean, free of burrs, and sized to the correct tolerance before driving the pin. Do not reuse a pin that has been removed, as repeated compression cycling can reduce retention force. Follow applicable machinery safety lockout and tagout procedures before servicing any assembly containing these pins.
