As with current margin rules, all short sales must be done in a margin account. If you sell short and then buy to cover on the same day, it is considered a day trade. Does the rule apply to day-trading options? Yes. The day-trading margin rule applies to day trading in any security, including options. What is a pattern day trader?
This is completely normal and is seen on $300+ Benchmade custom balisongs (tang pins deform or pivot screws back out). On a balisong with screw construction, LocTite is used to hold the pins in place. On FHMs, I use industrial strength epoxy.
A medium-strength thread-locking adhesive, usually blue, such as Loctite 242 is ideal for balisong applications. It's plenty strong for holding balisong fasteners and easily removed. The screws used on balisongs tend to be very small, #6, #4, or even smaller. For such small screws, only a tiny drop of the thread locking adhesive fluid is needed. In fact, I find that the dropper tip on the bottle that the adhesive comes in generally gives a drop that is way to large.
