Screws with a round head and an inner groove for a hexagonal wrench of the standard DIN 912 / ISO 4762. Such screws are used in air-modeling for the assembly and fixing of microengines and other parts in hard-to-reach places if there is a necessity of a reliable threaded joint. The hexagon socket screw is ideal to be used in places where it is impossible to use a wrench due to the limited space.
The main advantage of such screws is the shape of the slot. Slot - internal hexagon - has an advantage over cross and straight ones and allows you to attach to the fastener several times more torque when tightening.
The screws are made of carbon steels - strength classes 8.8, 10.9, 12.9.
This is a reliable fastener which can be used in constructions carrying huge static or dynamic loads.
The screws have a Black oxide coating.
The length of the hexagonal screw is measured from the bottom of the head to the end face of the threaded rod.
