MoodyFools' first tip: Don't crash!

Seriously though, here are a few tips and recommendation for when using light weight screws which are generally softer than steel screws.

 

Use the correct tool!

Most cars now days uses Metric screws and that is all we sell. Plase do not use Imperial drivers even though some will just about fit.

The screws we sell uses the following drivers:

M2.5 - 1.5mm hex driver

M3   - 2.0mm hex driver

 

Tool condidtion:

Always use a servicable driver with a sharp hex pattern! Titanium screws are softer than steel screws and if your hex tools tips are worn in anyway, change the tip to for new one to avoid risk of rounding off the hex head. Worn tools may be ok for steel screws but they can easily mess up titanium screws. If your tool have been used on Steel or Stainless steel screws before, we highly recommend that you change your tool tip for a new one when upgrading to Titanium screws, a small bit of investment will go a long way protecting your screws.

Tightening torque:

Do not use excessive force. I often see people over torque their steel screws thus damaging the thread of whatever they are screwing in to. With titanium screws not only the same could happen, but you can also damage the hex head too. Try holding the driver with three fingers instead of using your whole fist, turn the screw until resistance is felt, and then another quarter turn would normally suffice.

Right screw for the right job:

We do not recommend you use titanium screws for high stress areas such as mounting motors and certain types of hinge pin blocks where upon high impact they can result in bending. In thses areas steel/stainless steel or carbon steel is recommended.

Thread lock:

We generally do not recommend thread lock for building model cars. However, if you have to use thread lock of any kind, we recommend that you use the one made by Tamiya as it is probably one mild enough to allow disassembly. 

Screwing into hard plastics:

When screwing into hard plastics such as gear diffs or carbon loaded plastics for the first time, we recommend that you use the supplied steel screw first to gently tap the thread into the hard plasticpart, and always putting a little lubricant such as bearing oil or shock oil into the hole first. When done, remove the steel screw and replace it with the titanium screw.
