Bolt ART 88912 M5x12 10.9 toothed

The toothed flange protects the bolt from self-unscrewing during load moments, increasing the frictional force of touch. The notched flange fits snugly to the base of the material, preventing it from breaking under force.

The peculiarity of the ART 88912 bolt is that it is ideal for screw connections, when the bolt is screwed into the part, without fixing the nut on the reverse side, and the thread is cut in the body of the part. In such cases, locking from untwisting is required just under the bolt cap. And in order not to use the engraver, the design of the hat provides a flange with notches, which is much more effective at constant vibration loads. It can be used in through holes, with a fixing nut, but from unscrewing, the connection, in this case, must be protected in the place of clamping the nut to the part and the design features of the bolt cap will play almost no role. Therefore, it will not be a rational use of such hardware.

Scope mainly mechanical engineering, instrument making, automotive industry.

Material high-strength structural alloy steel. High strength class 10.9 allows the use of bolts for high-load connections.
