ProTek RC 3x25mm "Grade 5" Titanium Button Head Hex Screw (4)
About this part
ProTek R/C 3x25mm "Grade 5" Titanium Button Head Hex Screws are CNC machined and thread rolled to near-exact tolerances from high-quality 6AL-4V (Grade 5) titanium alloy material and polished to a brilliant finish. Titanium is strong, dense and super lightweight, and is a great way to reduce weight in low stress areas of the chassis. In fact, Titanium has one of the highest strength-to-density ratios of all alloys, making it a great option for dropping weight without sacrificing strength or durability.
6AL-4V Grade 5
6AL-4V, or more commonly known as Grade 5, is a Titanium alloy composed of 6% aluminum and 4% vanadium. It is significantly stronger than pure titanium but more expensive to manufacture. Grade 5 is the most widely used titanium alloy for its excellent combination of low weight, high strength and corrosion resistance.
To Maximize the life of ProTek R/C Titanium Screws:
- Never use with a worn Allen hex tip.
- Never use in areas where Loctite is to be used.
- Never use in high stress areas, such as shock mounts or chassis braces.
NOTE: Refer to your instruction manual for correct screw placement.

The worst set of screws I have ever dealt with. Not sure what grade these were, but decided to use them for a gear box. The heads stripped as if they were made of soft copper. Mind you, I was not using a power tool, I was using a 2.0 MIP hex driver and yet the tolerance of the hex on the screw was so poor that there was quite a bit of play to begin with. I'm starting to regret purchasing anything Protek. Bought a hauler bag, went bad. Bought a 3s protek lipo several years ago that went bad after a few uses and now these screws. I had to destroy the gearbox just to get the screws out. I would rate this zero if I could.
Bent the stock screws on a Losi DB pro the first time I ran it but these are WAY stronger and have been holding up great.
