ProTek R/C 3x20mm "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.

ProTek RC 3x20mm "Grade 5" Titanium Button Head Hex Screw (4)
I used these to replace the stock screws on an Arrma Kraton wing mount and they definitely have greater shear strength. The problem is the hexes are not strong at all! I strip 2 for every 1 that I can actually get installed, with standard steel screws working every time. I do not recommend these at all.
