The GBC fork-shaped pre-insulated terminal F.4 (model 18.3930.50) terminates flexible cables at M4 screw connections. The factory-fitted blue PVC sleeve insulates the crimp zone, removing the need for separate heat-shrink tubing.

Each terminal accepts cable cross-sections from 1.5 to 2.5mm² (AWG 16–14) and is rated to 300V. The pack contains 10 terminals.

Key Features

• Fork (spade) shape for M4 screw connections — no need to remove the screw fully
• Pre-fitted blue PVC insulation sleeve for a ready-to-crimp finish
• Tin-plated copper contact for corrosion resistance
• Screw hole diameter 4.3mm suits standard M4 hardware
• Compact body: 21.2mm length, 6.4mm external diameter

Product Benefits

• Pre-insulated design speeds up panel wiring without additional sleeving steps
• Blue colour coding follows IEC convention for 1.5–2.5mm² cable ranges
• 300V maximum voltage rating covers most low-voltage control and power circuits
• Tin-plated contact resists oxidation over time for stable conductivity
• Fork shape allows connection and disconnection with the screw left partially in place
