Better than spade connectors. No instructions though...need to look on line.

Absolutely love these connectors, use them all the time.

These work great, but theyre not overlap connectors. The OLC-1 , with a single set-screw, is an overlap connector. The OLC-2 is made for mostly single-strand thermocouple wire and the wires dont need to touch inside the connector, hence the 2 set-screws.

You either use these or youre wrong

The best type K thermocouple wire connector out there. Simple, streamline, fast and secure. Way better to use this than the JPI ring connector method.

Quality product, however an Allen wrench should be included.

These connectors work great. I am replacing all the crimp on connectors on my EI EGT and CHT probes. No more more lost signal.

I was first introduced to this style connector when one came in the box with a new Gold Cube fuel flow transmitter. That was the OLC-1 with a single set-screw. It made a very solid mechanical connection great for wires in a high-vibration area. The OLC-2 with two set-screws, though slightly bulkier, is a little easier to assemble and still makes a great connection. Im using them for every electrical connection in the engine compartment. PS. It would be nice if Spruce threw in the needed allen wrench with an order of connectors, as the manufacturer does...

No, it does not take a 3/64 hex driver, there is no such thing and the FAQ is wrong. Below 1/16, English-unit (ANSI/ASME) hex screws and drivers have decimal sizes and the set screw is 0.050 inches. This is indeed a standard size for hex screws and drivers and my discount Stanley socket set came with one. It is necessarily a bit small for some sets but its available.

These worked flawlessly making 8 connections between MGL “K” EGT probes and MGL E-1 gauge. The gauge now accurately reads EGT temperatures for my Rotax 582 engine.

Great for connecting Thermo couples wire

The use of a non standard set screw is a major drawback. 3/64ths is not in any set I have, and I have 5 sets.

I could not use these since they require an allen wrench in a size that is not generally available. Aircraft Spruce should have a link to and offer the wrench or modify the lksting to state the wrench size required. I went to several stores including a local hardware store that stocks everything and even they would have had to order the wrench. Instead I used the standard crimp connectors and overlapped the wires inside the jount instead.
