Non-tapping screws are machine Screw, the pieceworker to be fastened must be tapped with taps in the screw hole in advance to match the screw threads.
The difference between tooth screws and other screws depends on whether they can be used together with nuts. Tooth screws can be used with nuts. And relative to the screws of other teeth, there are self-tapping screws. The nut of this kind of screw has no bow teeth. As for the standard teeth and fine teeth are only different pitch, it is the nut of the machine screw

The first contract of the two parties lasted for five years and was devoted to the simulation modeling of the friction system. The primary goal of this collaboration is to further reduce friction and wear, thereby increasing the service life and environmental performance of SKF products.
– SKF has a long history of working with Imperial College London. According to Dr. Alan Begg, Senior Vice President of Technology, this collaboration aims to further enhance SKF's knowledge in the field of tribology, thereby strengthening the Group's leading position in bearing performance simulation.
The newly built Technology Center will be led by Professor Hugh Spikes of Imperial College of Technology. Professor Hugh Spikes is the head of the Institute's Tribology Research Group and has published more than 200 papers and patents in the field of tribology.
– Professor Spikes stated that Imperial College is very pleased with the decision to establish a technology center with SKF. This will not only promote basic research in tribology, but also ensure that scientific results can be applied to practical problems in the first place, such as reducing rolling bearings. Friction, reduce energy consumption, etc.
Technical center research will include: chemical composition of lubricants, fluid lubrication, elastic fluid lubrication, contact mechanics, wear and surface cracking, supplemented by computer simulations and theoretical studies.
In 2009, SKF partnered with the University of Cambridge to establish the Group's first university technology center.
