DIN 7513 Thread Cutting Screws, External Hex & Slotted Drive Thread Cutting Self-Tapping Screws
DIN 7513 thread cutting screws are heavy-duty self-tapping fasteners with slotted drive. The cutting flutes on the thread remove workpiece material and cut mating internal threads inside pre-drilled holes during installation.
We supply four main head styles:
DIN 7513 (A) Hexagon Head Thread Cutting Screws
DIN 7513 (BE) Slotted Cheese Head Thread Cutting Screws
DIN 7513 (FE) Slotted Countersunk Head Thread Cutting Screws
DIN 7513 (GE) Slotted Oval Head Thread Cutting Screws
External hex drive (Type A) can withstand extremely high tightening torque for heavy load applications. Slotted drive versions are widely used for general industrial assembly. Optimized thread geometry delivers clean thread formation, reduces driving torque and minimizes stress on the workpiece.
Carbon steel versions are case-hardened to guarantee reliable cutting performance. Stainless steel grades are available for corrosion-resistant environments. These screws are widely used in machinery, cast iron, thick sheet metal, automotive assemblies and industrial structural components. Custom specifications are accepted for special engineering projects.
