Excuse Me Stainless Steel Screw Easy To Bite, The Titanium Screw Will Bite?

I think the main reason for the screw bite is that the contact surface is sticky due to the interaction between the thread of pretightening force and the toughness of metal itself due to the micro creep deformation. Titanium is a memory metal, and shape memory can be worse. That's why a chewed bolt can be easily removed by heating and expanding it. There is also a key point, if the screw and equipment material is different, the potential is different, will produce electrochemical corrosion after bite.
