AWG 20/0.75mm² Ferrules

Ten-pack of insulated bootlace ferrules for clean AWG 20 / 0.75mm² stranded-wire terminations. These ferrules crimp onto stripped stranded conductors so screw and spring terminal blocks grip a contained metal sleeve instead of loose copper strands.

Why use ferrules here

• Helps keep stripped strands from fraying, pulling loose, or bridging the next terminal position.
• Gives printer/control wiring a repeatable end when landing in controller boards, DIN terminals, power-supply blocks, and screw-clamp connectors.
• The black insulated collar makes handling easier while the tinned sleeve takes the crimp; use a proper ferrule crimper instead of solder-tinning wires for screw terminals.

Specifications

• Quantity: 10 ferrules
• Wire size: AWG 20 / 0.75mm² class stranded wire
• Style: single-wire insulated cord-end / bootlace ferrule
• Construction: black plastic collar with tinned metal crimp sleeve
• Use with: stranded wiring landed in terminal blocks, screw clamps, and spring-clamp terminals

Printer wiring fitment

Use these anywhere a stranded conductor needs a clean crimped end before it goes into a terminal block: controller power wiring, accessory wiring, heater or fan leads where the conductor size matches, and enclosure/control-box wiring on Voron, Klipper, CNC, and other printer electronics. They pair well with terminal-block wiring such as the 2-pin P=5.08mm screw terminal; check the conductor and insulation diameter against the ferrule collar before crimping.

Pick the right size

Ferrules should match the conductor cross-section, not the terminal screw size. For larger wire, use AWG 18 / 1.0mm² ferrules; for smaller wires, see AWG 24 / 0.34mm² ferrules or AWG 26 / 0.25mm² ferrules.

What it is not

• Not a solder sleeve, splice, or connector housing.
• Not for solid-core wire or two wires in one ferrule; use the correct twin ferrule for doubled conductors.
• Not a substitute for matching the ferrule and crimp tool to your actual conductor OD.
