The T-bolt can be directly placed into the aluminum profile groove, and it can automatically position and lock during installation. It is often used in conjunction with flange nuts and is a standard matching connector for installing corner pieces. It can be selected and used according to the width of the profile groove and different series of profiles.
GB62.2 Butterfly Nut (Square Wing Butterfly Nut) is mainly used in occasions that require frequent disassembly and installation, especially suitable for furniture, mechanical equipment, and automotive fields. Its design features include flat square wings on both sides, allowing the nut to be easily rotated by fingers without the need for tools, thereby improving the convenience and efficiency of operation.
The head of a hex flange bolt consists of two parts: the hexagonal head and the flange face. Its “support area to stress area ratio” is larger than that of a regular hexagonal head bolt, so this type of bolt can withstand higher pre tightening forces and has better anti loosening performance. Therefore, it is widely used in products such as automotive engines and heavy machinery. Hexagonal head bolts with holes and grooves can be mechanically locked to prevent loosening during use.

DIN935-1 hexagonal slotted nuts are mainly used to fix the front and rear axles of vehicles. By tightening the screws that pass through the front and rear axles, the frame and tires are fixed together. In order to prevent the nut from loosening, it is usually fixed by using an open-ended pin that passes through the groove of the slotted nut. The open-ended pin needs to pass through the middle of the wheel axle screw, and usually both ends of the wheel axle screw need to be drilled. The diameter of the hole and the width and depth of the slotted nut groove determine what specification of open-ended pin is selected.
