    The US has launched the innovative generation of Backer-On and Rock-On cement special screws. These two screws all have sawtooth heads, T-25 angle drive parts and serrated threads and so on to solve the challenges faced by general contractors and enhance their performance. The performance of innovation includes:


    1. The design of the sawtooth head. The head can be pasted and firmly positioned in the target to reduce the chance of cracking of the cement board.


    2, match the five angle driving part of the T-25 bit. The five corners of the groove can be fitted with any screws so that the user can operate on one hand without damaging the drill bit.


    3. Sawtooth thread. The improved thread can achieve faster installation with less torque.


    4, sharp tail and leading thread, so that users can quickly pick up the screws and reduce the strength of the screw.
