ELECTRAPICK 10Pcs 10 Gauge Wire Connectors Nut,60 Amp Splicing Quick Wiring Connection Terminal,Circuit Connector Wire Connector with 20Pcs Screws & 10Pcs Heat Shrink Tube

The ELECTRAPICK heavy duty inline wire connector kit comes with everything needed including the hex wrench and pre-cut single wall heat shrink tubing. Installation is easy as the 0.14 inch opening for the wire is large enough to comfortably insert 10 AWG THHN stranded wire without the strands binding or bending. There is enough room to insert a THHN stranded wire with a crimped ferrule into the connector, and, of course, a solid AWG 10.The in-line design is quick and easy to assemble, provides a low-resistance connection capable of carrying more current than the wire itself, and is less bulky than many other connectors. I use these for AC circuits, DC work, and for antennas.

The locking allen screws could have been a little bit shorter because they stick out from the brass cylinder about 1/8” after tightened. They were covered nicely by the heat-shrink, but I would rather that they didn’t protrude away from the cylinder. It does make a strong, quality connection and better than wire nuts for my particular application, where space was not an issue.

Well made with fine-threaded set screws and long (50mm) heat shrink tubing.Fits my hard-aluminum wire (fence wire, I think) for my antenna project perfectly.I wish the brass tube was a bit longer - its only 15mm long.
