The T-bolt can be directly inserted into the aluminum 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 when installing corner pieces. It can be selected and used according to the width of the groove and different series of profiles. T-bolts belong to movable anchor bolts.
T-shaped bolts belong to movable anchor bolts, and the raw materials are 304 stainless steel plate and medium carbon steel. The surface of medium carbon T-shaped screws can be hot-dip galvanized or nickel plated.
It can be immediately inserted into the groove and can be automatically and accurately positioned and clamped throughout the entire installation process. T-bolts are usually used in conjunction with flange nuts. They are standard connection standard parts when installing corner pieces. Use T-bolts according to the width of the aluminum groove.
Standard for T-bolts
T-bolt standard GB/T37-88; The national standard for T-bolts specifies thread specifications of M5-M48, and B-grade T-bolts. This standard specifies hexagonal head bolts with thread specifications ranging from M1.6 to M64, performance grades of 5.6, 8.8, 9.8, 10.9, A2-70, A4-70, A2-50, A4-50, CU2, CU3, and AL4, and product grades of A and B. Grade A is used for d=1.6-24mm and l ≤ 10d or l ≤ 150mm (whichever is smaller); B-grade is used for bolts with d>24mm or l>150mm (whichever is smaller). If other technical requirements are required, they should be selected from current standards (such as GB/T196, GB/T3106, GB/T3098.1, GB/T3198.6, and GB/T3103.1).
At present, commonly used are DIN186 T-shaped square neck bolts, national standard GB37, DIN188T double neck bolts, materials include carbon steel, stainless steel, alloy steel, etc., with specifications ranging from M8-M64.
