Why Choose the BS43N Partex Blue 4 mm Narrow Fork Crimp Terminal?
The BS43N Partex Blue 4 mm Narrow Fork Crimp Terminal is engineered for precise, space-efficient termination of 1.5–2.5 mm² stranded copper conductors onto M4 studs or screws. Featuring a pre-insulated blue PVC sleeve, it enables rapid wire gauge identification, safer handling, and repeatable crimp quality. Manufactured from high-conductivity C1100 copper and certified to UL File E163810, the BS43N delivers low contact resistance and dependable mechanical retention in compact control panels, terminal blocks, and machine wiring applications.
Supplied in a pack of 100, this UL approved narrow fork terminal is trusted by electricians, panel fitters, and OEM technicians who require compliant, screwdriver-clear termination solutions in tight wiring environments.

Frequently Asked Questions
What wire sizes are compatible with the BS43N terminal?
The BS43N is designed for 1.5–2.5 mm² stranded copper conductors, equivalent to approximately 14–16 AWG, consistent with blue insulation coding standards.
Does the BS43N fit M4 screws or studs?
Yes. The BS43N is engineered for precise installation on 4 mm (M4) studs or screws commonly used in compact control panel wiring.
Is the narrow fork design necessary in tight spaces?
Absolutely. The narrow fork profile allows termination beneath partially loosened screw heads and within densely populated wiring environments without removing hardware completely.
Which tool is recommended for BS43N?
A calibrated ratchet-style crimping tool designed for insulated terminals in the 1.5–2.5 mm² range ensures consistent crimp quality and conductor retention.
Can the BS43N be used with solid-core cable?
While optimised for stranded copper conductors, the BS43N may also be used with solid-core wire when properly crimped using suitable tooling.
What is the operating temperature range?
The BS43N is rated for continuous operation between -40 °C and +105 °C, suitable for industrial and control panel environments.
What does blue insulation indicate?
Blue PVC insulation signifies compatibility with 1.5–2.5 mm² conductors according to recognised international colour coding standards.
