In the field of aluminum profile assembly, T-bolts are well-deserved "high-efficiency fasteners". They also go by alternative names such as Hafen slot bolts and T-screws. Relying on their unique structural design and convenient installation characteristics, they have become indispensable core accessories for building aluminum profile frames. The most notable advantage of these bolts lies in their flexibility and adaptability during installation—there is no need to pre-drill holes in the profiles; they can be directly inserted into the grooves of aluminum profiles. During the subsequent tightening process, the bolts can automatically fit and position themselves with the grooves to achieve locking, which greatly simplifies the assembly process. This makes them particularly suitable for on-site rapid assembly scenarios.
The use of T-bolts usually cannot do without the "collaboration" of flange nuts. Together, they form a standard matching fastener set, playing a key role in installing angle fittings such as angle brackets, supports, and panels. The anti-slip threads and large contact area of flange nuts can further enhance the stability of the connection, preventing the bolts from loosening in vibrating environments. At the same time, they disperse pressure to avoid deformation of the aluminum profile surface due to excessive local stress. This combination is widely used in aluminum profile structures such as industrial frames, display stands, and protective covers for automated equipment.
Selecting the right T-bolts requires multi-dimensional consideration based on actual needs. Firstly, selection should be based on the groove width of the aluminum profiles. Different specifications of aluminum profiles (such as European standard 3030, 4040, and Chinese standard 2020) correspond to different groove widths. The width of the "T"-shaped head of the bolt must match the groove width accurately to ensure smooth insertion and stable locking. Secondly, judgment should be made based on the profile series and application scenarios—small T-bolts can be used for light-duty frames (such as display cabinets and workbenches), while high-strength specifications should be selected for industrial equipment frames that bear heavy loads to meet load requirements. In addition, the environmental characteristics of the installation location also affect the selection: in humid environments, priority should be given to surface treatments with corrosion resistance; in high-temperature scenarios, attention should be paid to the heat resistance of the material.
In terms of materials and surface treatments, T-bolts also offer a wide range of options. Common materials include carbon steel and stainless steel. Carbon steel bolts are lower in cost and suitable for dry, non-corrosive indoor scenarios. 304 stainless steel, with its excellent rust resistance, has become the first choice for humid environments (such as bathroom equipment frames) and outdoor scenarios (such as photovoltaic brackets). Surface treatment processes also have different focuses: galvanizing can improve the basic rust resistance of carbon steel bolts, while nickel plating combines rust resistance with aesthetics, making it suitable for display-type aluminum profile structures that have appearance requirements. This diverse range of options allows T-bolts to adapt to different working conditions and provide reliable support for aluminum profile connections.
