Tapping screw That is to say, the biggest difference between self-drilling tapping screws and self-tapping screws is that there is no need to drill prefabricated holes. Installation of self-tapping screws before the need to play a good prefabricated holes, and in order to play a good fit, self-tapping screws prefabricated holes, the tolerance requirements are relatively strict.
Self-drilling tapping screws thread pitch, tooth angle and tapping screws consistent, the biggest difference is that self-drilling tapping screws threads are not designed with a drill-like ‘pointed tail’, this ‘pointed tail’ is used for drilling.
Therefore, in the fastener industry, we are accustomed to the self-drilling tapping screw image called ‘drill tail nail’.
Common flange connection, threaded connection and socket connection. The flange connection has the advantages of reliable sealing, sufficient strength and wide application range.
Carbon steel fasteners are widely used in industryfurniture decoration and other industries, makingthem unanimously welcomed by various industries.
Self-drilling tapping screws do not need to play the prefabricated holes, you can achieve the assembly, in one sentence to sum up the characteristics of the self-drilling tapping screws is to achieve the drilling, tapping and fastening at the same time a one-time operation. It greatly reduces the assembly cost and improves the assembly efficiency.
Bentley has invested a huge amount of money to build a product testing laboratory, equipped with imported high-end instruments: such as thread comprehensive scanners, high temperature tensile testing machines, high frequency fatigue testing machines, etc., to ensure that all products are strictly tested before leaving the warehouse to ensure the reliability of customers during use.
