These titanium screws are the way to go if you want to reduce weight on your vehicle. I got this item and it comes neatly in its own storage box, which is handy. It says its for Tamiya product but i suppose you can you it on most vehicle as most kits uses the same screws only being its either a phillip head, flat head or hex head thats different. These are great because they also dont rust and being titanium they are light but strong. If you want screws that wont rust you will need stainless stell and as you all know they weigh more. The only down side i find with using titanium screws is they tighten abit harder down the long run and if its a hex style screw and you turn the driver and it slips, you will have a hard time getting it out. But it they are used on composite then its great!
