Why Choose the Partex BS43/RA Blue Insulated M4 Spade Terminal?
The Partex BS43/RA is a professional-quality blue insulated M4 spade crimp terminal, also known as a fork terminal, designed to provide secure and convenient electrical connections to compatible screw terminals. Suitable for electrical control panels, industrial machinery and equipment wiring, it offers a practical solution where reliable electrical termination and straightforward maintenance access are required.
Featuring an M4 fork connection and blue insulation, the terminal is designed for the commonly used 1.5–2.5 mm² conductor range, approximately equivalent to 16–14 AWG. Its open-ended fork design allows the terminal to be positioned beneath a suitable screw head or washer without completely removing the fastening hardware, helping simplify installation and maintenance.
Supplied in a convenient pack of 100 terminals, the Partex BS43/RA is ideal for electrical panel builders, automation engineers, OEM equipment manufacturers and maintenance professionals who require consistent, organised cable terminations.

Convenient M4 Fork Connections for Electrical Control Panels
Spade terminals are commonly used in electrical installations where conductors need to be connected to screw terminals while allowing convenient access during assembly or maintenance. The Partex BS43/RA features an open-ended fork designed for compatible M4 screw connections. Unlike a closed-ring terminal, a fork terminal can be removed from suitable fastening hardware after the screw has been loosened sufficiently, without completely withdrawing the screw.
This design makes the BS43/RA particularly useful in electrical control panels, equipment assemblies and maintenance applications where connections may need to be inspected, replaced or repositioned. The blue insulated crimp barrel helps identify the conductor size and provides a protective covering around the cable termination.
For dependable electrical performance, the conductor should be correctly stripped and crimped using a suitable tool and die for 1.5–2.5 mm² insulated terminals. The fork must be positioned correctly beneath compatible fastening hardware and tightened according to the equipment manufacturer's requirements. Fork terminals should only be used where the connection arrangement is designed to retain them securely.
