I made up a set of these suds today. I just realised I missed your note about the pin through the wing nut. I wrenched mine on pretty tight today then peened over the top. I don't think they will work loose at all.

The hole in the nut is for lock wire..usually monel with lock wiring pliers to apply..
Used on aircraft or high vibration fasteners that are in high vibration areas.

From Wiki..
Safety wire or lockwire is common in the aircraft and racing industries as an extra precaution to keep vital fasteners from unintentionally loosening and parts from falling off due to vibration or other forces. The use of safety wire is a type of positive locking device. It also allows rapid and easy visual inspection of fasteners to ensure that they have been tightened. Safety wiring of fasteners is often a requirement to pass technical safety inspections in motorsport racing. Safety wire itself is available in multiple gauges and different materials, depending on the application. In consumer aircraft and racing applications, stainless steel wire is used, most commonly in .032" diameter, although other gauges are used for specific circumstances. Typically, safety wire is threaded through a hole drilled into a fastener or part, then twisted and anchored to a second fastener or part, then twisted again, usually with the aid of safety wire pliers.

I used to teach safety wiring when I was an airframe instructor in Borden.
There are two types of wire monel and inconel for high heat applications.
Wire sizes range from .0010 copper for witness wire, .0020, .0032, .0040, and .0060 thou.
You only really need a pair of duckbill pilers and sidecutters but wire twisters can really make a professional looking job, and yes they are made to twist left and right.
Any one who owns a WLA OR WLC would greately penifit from using drilled nuts on the engine and transmission they are'nt called Miliwakee vibrators for nothing.
Vibration can loosen locktite and cause lockwashers to loose their grip, safety wiring is your last line of defense.
