Review on 🔧 Astro 9477H1 H1 Jaw - Spark Plug Connector, 17 Gauge, 1 Meter DIN Cable by Tim Thornton

I don't do a lot of connector wires but after screwing one up the professional look and secure fit was totally worth it. Other small crimping pliers also came in handy where some other jaws weren't crimping properly. The Astro cheek markings are a bit annoying. The only downside is that they are longer than any other jaws and due to the way they snap into the tool, there can be minor tip registration issues if they don't want to engage. Exactly. A few times I just had to pinch it with my fingers to flatten it and then crimp it all the way.
