(1) Bolts mainly include special bolts, special round head bolts, special round head bolts, flat head bolts and T-bolts. Industrial aluminum frames usually use the internal connection method, using special round head bolts or special bolts. Before installation, thread and process mounting holes must be tapped at profile connections; Special round head bolts are commonly used for high strength connections of two-section profiles. Drilling and tapping in a predetermined position; Flat bolts are matched with T-nuts and are commonly used to connect decorative parts, such as hinges and handles with profiles; T-bolts are placed directly into the recesses of the profiles and can be installed during installation. Automatic positioning and locking, usually used with flange nuts. This is an important connection for mounting Angle fittings and other profile fittings. T-bolts of different specifications and lengths can be selected according to different profiles, slot widths and installation requirements.
(2) Nuts mainly include flange nuts, square nuts, T nuts and elastic nuts. The flange nut is matched with the T-bolt and is used when installing Angle fittings and other profile fittings. The T-nut allows other connectors to be easily and safely secured into the grooves of the profile and automatically positioned and locked during assembly. In the installation process, the square nut needs to be inserted into the groove of the profile to connect the various fittings on the profile. The elastic nut can be directly inserted into any assembly point in the profile groove, and the spring steel ball on the back can hold it in place, so the installation is very simple and reliable, and it is one of the most commonly used accessories.
(3) Angle fittings are commonly used connector for aluminum profiles. They are commonly used for vertical or cross connection of aluminum profiles. There are mainly three kinds of commonly used Angle accessories, strong Angle accessories and steering Angle accessories. Common corners are used to enhance support for connecting contour points and can also be used as a connection method for contoured objects that need to be moved. Strong Angle parts are usually used to support and fix the contour and contour points affected by force or vibration; For steering Angle parts, connected with a cross profile.
