DIN 913 socket screws, also known as flat-headed screws with internal hexagons, are designed for internal fastenings or adjustments on shafts, gears and mechanical components where a protruding head is not required. As they have no head, they screw completely into the housing, providing a concealed and secure mounting.
Their socket key drive facilitates precise application of torque, while the flat tip distributes pressure evenly over the contact surface, preventing damage to the part being fastened. They are commonly used in mechanical systems, couplings, rotating shafts and transmission equipment.
DIN 913 screws: internal fastening with flat tip
At CHAVESBAO, we offer DIN 913 socket screws manufactured to standard in A2 stainless steel for assemblies exposed to moisture. This variety of materials allows them to be used in standard machinery, precision applications or corrosive environments.
The flat tip of the DIN 913 is ideal for holding parts in position without marking the surface, making them particularly useful in fine adjustment components or moving parts. In addition, their headless design allows them to be completely flush, optimising space and improving assembly safety.
