Products Details

According to the force mode of connection, there are ordinary and reaming holes. Flange bolts for reaming holes are to be fitted to the dimensions of the holes and used when subjected to transverse forces. In addition, in order to meet the need of locking after installation, there are holes in the rod, which can make the bolt not loose when it is vibrated. Some flange bolts have no threaded smooth rod parts to do, called thin rod flange bolts. This flange bolt facilitates joint subjected to varying forces. Flange bolt is composed of hexagonal head and flange plate, its "support area and stress area word ratio" is greater than ordinary bolt, so this bolt can withstand higher preload, anti-loosening performance is also better, so it is widely used in automotive engines, heavy machinery and other products.   Handan Chang Lan Fastener Manufacturing Co., Ltd. formerly Yongnian Tiexi Changhe fastener factory was large-scale standard fastener manufacturer in Yongnian District.
