Why Choose the Partex BFS53 Blue Insulated Flanged Spade Terminal?
The Partex BFS53 is a practical and reliable blue pre-insulated flanged spade crimp terminal designed to provide secure electrical connections to compatible screw and stud terminals. Featuring an M5 fork connection and a flanged spade design, this terminal is suitable for industrial control panels, electrical equipment wiring, machinery and general electrical installation applications.
As part of the Partex insulated crimp terminal range, the BFS53 combines a conductive metal terminal with protective blue insulation to support dependable electrical terminations. Its fork-shaped contact allows installation beneath a compatible screw head or terminal clamp without requiring the screw to be completely removed. The flanged design provides additional retention around the fastening point, helping maintain a secure connection when correctly installed.
Designed for the 1.5–2.5 mm² conductor range associated with blue insulated crimp terminals, the Partex BFS53 features an M5 connection size and is supplied in a convenient pack of 100 pieces. Its colour-coded insulation, straightforward crimp installation and practical fork configuration make it suitable for electricians, control panel manufacturers and industrial maintenance engineers.

Reliable Flanged Spade Connections for Electrical Control Systems
Flanged spade terminals such as the Partex BFS53 provide a convenient method of connecting electrical conductors to screw-type terminals. During installation, the conductor insulation is stripped to the appropriate length, the conductor is inserted into the crimp barrel and a compatible crimping tool is used to secure the termination. The fork contact is then positioned beneath the terminal screw or clamping arrangement and tightened according to the equipment manufacturer's instructions.
The M5 flanged fork design offers a practical combination of installation convenience and mechanical retention. Unlike closed-ring terminals, a fork terminal can generally be fitted or removed by loosening the fastening screw without completely removing it. The flanged ends help resist the terminal slipping from beneath the fastener when correctly secured. Its blue insulation provides convenient identification for the nominal 1.5–2.5 mm² conductor range, making the BFS53 suitable for organised electrical panel wiring and equipment assembly.
Typical Applications

Frequently Asked Questions
What is the Partex BFS53 used for?
The Partex BFS53 is a blue insulated flanged spade crimp terminal used to connect electrical conductors to compatible M5 screw or stud terminals in control panels, industrial equipment and electrical installations.
What screw size does the Partex BFS53 fit?
The BFS53 is designed for an M5 screw or stud connection, corresponding to a nominal fastener diameter of 5 mm.
What wire sizes are suitable for the Partex BFS53?
The blue insulated BFS53 is intended for the 1.5–2.5 mm² conductor range, approximately equivalent to 16–14 AWG. The conductor and crimping tool must be compatible with the terminal.
What does the flanged spade design provide?
The flanged fork configuration incorporates shaped ends around the open fork, helping improve retention beneath a compatible screw or terminal clamp when the connection is correctly tightened.
Does the Partex BFS53 require the terminal screw to be removed?
Normally, no. The open fork design allows the terminal to be positioned beneath a loosened screw head or terminal clamp without completely removing the screw, provided the receiving terminal is suitable for this connection method.
How many Partex BFS53 terminals are supplied in one pack?
The Partex BFS53 is supplied in a pack of 100 pieces, making it suitable for electrical installation, panel manufacturing and routine maintenance work.
What tool is needed to install the Partex BFS53?
A suitable crimping tool for blue pre-insulated terminals should be used. The tool must accommodate the specified conductor cross-section and form a secure crimp without damaging the terminal.
What is the difference between a flanged spade terminal and a ring terminal?
A flanged spade terminal has an open fork that can usually be installed beneath a loosened screw, while a ring terminal has a closed circular connection that generally requires the fastener to be removed for installation or disconnection.
Is the Partex BFS53 suitable for industrial control panels?
Yes. The Partex BFS53 is suitable for industrial control panel and electrical equipment wiring where an M5 fastening point, the specified conductor range and a compatible terminal connection are provided.
