The T bolt is literally understood to be that the shape of the bolt is like a capitalized English letter “T”, which has its reputation.

Some T bolts are also called T screw or T type screw. The aluminum alloy profiles are T type bolts and hammerhead bolts. The materials are SUS304 stainless steel and medium carbon steel, medium carbon steel T screw surface can be galvanized or plated with nickel and dacrop, and the carbon steel T bolts are made of 1045 medium carbon steel, production of red satin and the grade after heat treatment. For the 8.8 grade, it is generally a die plate bolt. The T type screw can be put into the slot directly. It can be automatically locked in the installation process. The T bolt is used in general with the flange nut. It is the standard connection fastener for the installation of the corner parts, and the T type bolts are selected according to the width of the profile.

GB GB37-88T groove bolt, this standard specifies the B grade T type slot bolt with thread specification of M5-M48. This national standard is less than or equal to less than M39 diameter, and the mechanical performance grade is generally 8.8 levels. The mechanical performance of the M39 is generally agreed with the customer negotiation; and the standard shows: “because of the structural reasons, the T shaped groove bolts do not carry on the load and the joint strength test of the head rod”. M5, M6, M8, M10, M12, M16, M20, M24, M30, M36, M42, and M30 have 12 specifications, the shortest length is 25, the longest is 300..

Machinery industry standard JB/T 8007.2-1999| machine tool fixture parts and components T groove quick unloading bolts.

The surface treatment is mainly chemical blackening and galvanizing passivation.
