Connector BLOW 43-002# insulated fork (spade) screw 3.7 mm for 4.3 mm cable

Connector BLOW 43-002# insulated fork (spade) screw 3.7 mm for 4.3 mm cable is an electrical termination designed to provide a safe, insulated connection between a stranded or solid conductor and screw-type posts or terminal blocks. The fork (spade) shape allows quick installation without fully removing the screw, while the insulated sleeve reduces risk of accidental short circuits and improves handling during assembly and maintenance in automotive, industrial and household wiring tasks.

Advantages

The insulated fork connector combines a compact metal spade with a molded insulating sleeve, delivering mechanical stability and electrical insulation in a single component. Its 3.7 mm screw opening matches common terminal studs, enabling reliable contact and consistent current transfer. The design supports fast crimping and simple visual inspection of the conductor insertion, reducing assembly time and minimizing risk of loose connections.

Suitable for

• Connecting 4.3 mm diameter conductors to screw-type terminals
• Automotive wiring harness repairs and modifications
• Industrial control panels and terminal blocks
• Household electrical devices and appliances requiring insulated spade terminations

Key specifications

• Conductor accommodation: for cable with approximately 4.3 mm conductor diameter
• Screw terminal diameter: fits 3.7 mm screw posts
• Contact form: fork (spade) for easy assembly under screw
• Insulation: molded sleeve to prevent accidental shorts and provide strain relief
• Material: conductive metal spade with insulating polymer sleeve

How to use

Strip the cable insulation to expose the required length of conductor, ensuring the conductor diameter matches the connector's specified accommodation. Insert the conductor fully into the metal barrel of the fork connector and apply a suitable crimping tool to achieve a secure mechanical and electrical joint. Slide the insulation sleeve over the crimped area if not pre-assembled, then position the fork under the screw head or around the stud and tighten the screw to the manufacturer's recommended torque for the terminal. Inspect the connection to confirm the conductor is secured and the insulating sleeve prevents contact with adjacent conductors.

Usage recommendations

Use an appropriate crimping tool rated for insulated terminals and verify compatibility with the cable cross-section. Avoid over-tightening the screw to prevent deformation of the fork and ensure torque is within terminal specifications. Select connectors rated for the system current and environment; in high-vibration or high-temperature applications, consider additional retention or heat-resistant variants.
