Descriptions of square head screw:

Characteristics of square head screw:

1.This T-shape bolt for grooves conforms to GB37-88 standard and it can be used together with T-shape groove and the thread on it will help to finish the fixing works.

2.The nut length of T-shape bolt is larger than the internal height of the built-in notch. Therefore, while using, the nut should be firstly put into the groove and when the outside connection is finished, the nut can be screw tightly. Because of the long inside nut, the nut will be blocked in the groove when screw into a certain angle, then the outside nut can be screwed at this time to finish the fixing and installation works.

3.This kind of bolt is forge from #45 steel and it is also performed with quenching and tempering process. T-shape bolt and C-shape groove embedded parts both have tensile resistance force not less than 70 KN. The thread of it conforms to GB196 and GB197 standards. T-shape bolt is specially designed for groove embedded parts and it can be installed quickly and no welding is needed.

4.The nut length of T-shape bolt is larger than the internal height of the built-in notch. Therefore, while using, the nut should be firstly put into the groove and when the outside connection is finished, the nut can be screw tightly. Because of the long inside nut, the nut will be blocked in the groove when screw into a certain angle, then the outside nut can be screwed at this time to finish the fixing and installation works.
