Value Collection R57900645 Slotted Spring Pin 14mm 4mm Steel

Product Description

The VALUE COLLECTION R57900645 is a slotted spring pin manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins, also called roll pins or tension pins, are cylindrical fasteners with a longitudinal slot that allows radial compression during installation. This compression creates a press-fit retention force inside a drilled hole, locking shafts, levers, and linkages without threads or additional hardware. At 14 mm in length and 4 mm in diameter, this pin is suited for light- to medium-duty metric fastening applications in mechanical assemblies, machinery, and industrial equipment. Machinists, maintenance technicians, and assembly workers are the primary installers.

This pin is used in metric mechanical assemblies where a removable or semi-permanent shaft retention solution is needed. Typical applications include gear and shaft assemblies, hinges, linkages, and fixture components found in industrial machinery, agricultural equipment, and general manufacturing. The metric dimensioning and 1070-1080 steel construction make it appropriate for applications requiring moderate hardness and shear strength without corrosion-resistant plating. The plain finish is suitable for indoor or protected environments where surface exposure to moisture is limited.

Key Features

• Slotted design allows radial compression for secure press-fit installation in drilled holes
• 1070-1080 grade steel construction provides moderate hardness and shear strength
• Plain finish keeps installation simple in dry or protected indoor environments
• Metric dimensioning suits machinery and equipment specified in millimeters
• No threads required — retained by spring tension alone for easy removal and reinstallation

Compatibility

Designed as an OEM-style replacement or stock fastener for metric mechanical assemblies requiring a 4 mm diameter slotted spring pin in a 14 mm installed length.

Installation Notes

Installation is performed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. The receiving hole must be drilled to the correct nominal diameter to ensure proper spring retention force. De-energize, de-pressurize, or lock out any machinery before installing or removing spring pins from live assemblies. Avoid using oversized holes, as this will reduce retention force and compromise joint integrity.
