Why Choose the Partex BFS43 Blue Flanged Spade Terminal?
The Partex BFS43 is a professional blue insulated flanged spade terminal designed for secure electrical conductor termination in industrial control panels, machinery wiring and electrical equipment. Featuring an M4 fork connection, this crimp terminal provides a practical method of connecting electrical conductors to compatible screw and stud terminals.
The BFS43 features a flanged fork design that helps retain the terminal beneath a suitably matched screw head or washer. Unlike closed-ring terminals, fork terminals can be fitted or removed without completely extracting the fastening screw, making them convenient for electrical installation, inspection and maintenance.
Supplied in a pack of 100 blue insulated terminals, the Partex BFS43 is suitable for electricians, panel builders, maintenance engineers and OEM manufacturers who require consistent, professional electrical connections for repetitive wiring tasks.
