Phillips hex washer head Trilobe thread rolling screws DIN 7500
a) DIN 7500 specifies self-tapping screws for metal, also known as thread-forming screws. These screws are designed to form or cut threads in a pre-drilled hole in metal materials, without requiring a pre-cut thread.
b) Three indentations on the thread allow better debris clearance and assist in the thread-forming process.
c) A standard trilobe thread forming screw without indentations is avaialble upon request.
Pan head trilobular thread rolling screw DIN 7500
a) DIN 7500 specifies self-tapping screws for metal, also known as thread-forming screws. These screws are designed to form or cut threads in a pre-drilled hole in metal materials, without requiring a pre-cut thread.
b) The screw shank has a three-lobe shape instead of a round cross-section, which reduces friction during installation, and facilitates smooth material displacement and efficient thread formation.
c) The long dog point (the extended, unthreaded tip of the screw) acts as a pilot, helping to align the screw with the pre-drilled hole during installation, and faciliates smooth installation.
d) A standard trilobe thread forming screw without dog point is avaialble upon request.

DIN 34800 External Hexalobular Drive Head Bolt With Small Flange
a) This bolt features an external hexalobular socket with a small flange, and is designed for applications requiring a high torque transfer with reduced risk of cam-out.
b) The star-shaped head allows for great torque transfer by distributing the load more evenly across the drive, compared to traditional drive systems like Phillips, Pozi or slotted.
DIN 7504K Hex washer head self drilling screw
a) A self-drilling screw is a type of screw designed to drill its own hole and tap its own threads into materials as it is driven in, eliminating the need for a pre-drilled hole. The screw features a drill-like tip, often referred to a self-drilling tip, which helps the screw cut through the material. This makes installation faster and more efficient.
b) Serrations under head create additional friction between screw head and the material. The serrated surface provides better grip for tools like screwdrivers, allowing more torque to be applied during installation.
