The GBC fork-shaped pre-insulated terminal F.5 (model 18.3931.40) terminates flexible cables at M5 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 screw hole diameter of 5.3mm and external body diameter of 8.1mm distinguish it from the F.4 variant. The pack contains 10 terminals.

Key Features

• Fork (spade) shape for M5 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 5.3mm suits standard M5 hardware
• Body dimensions: 21.2mm length, 8.1mm 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
