Shandong Jingmei industrial aluminum profiles have many connection methods. If you want to ask which connection method is the most secure, it should be hexagon socket bolts. Why is a small bolt with the highest connection strength? This is because in the process of connection, it is necessary to tap threads to increase friction, and then cooperate with elastic fasteners and special round head bolts, so the connection strength is high. The specifications of hexagon socket bolts are: m (thread size) *6/8/10/12/16/20/25/30/35/40 (the following numbers are length, in mm). M (thread) specification: m4/m5/m6/m8/m10/m12 (general thread of corner fitting <m8), select the corresponding bolt thread according to the supporting nut. Suggestion: the bolt length used for assembling the corner fittings of various series of profiles is as follows: 20 series (angle fitting) bolt length: 10mm. Length of bolts used in 30 series (angle fitting parts): 12mm. 40 series (angle fitting) bolt length: 16mm. Hexagon socket bolts can be used not only to connect profiles, but also to connect various accessories. When connecting accessories, it needs to be used with nuts. There are differences between the nuts used in national standard profiles and European standard profiles. For example, European standard profiles are often matched with T-shaped nuts or slider nuts, and national standard profiles are often matched with T-shaped nuts or square nuts.
