DIN7991 COUNTERSUNK HEAD SOCKET CAP SCREWS
DIN7991 FLAT COUNTERSUNK HEAD SOCKET CAP SCREWS
DIN 7991 Flat Countersunk Head Socket Cap Screws are specialized fasteners that conform to the German Institute for Standardization (DIN) specifications. They feature a flat head with a conical shape underneath, which allows them to sit flush with the surface of the material they are fastened into.
The internal hex socket drive ensures precise torque control and ease of installation using an Allen wrench. Manufactured from materials such as stainless steel and alloy steel, these screws are known for their strength and corrosion resistance.
DIN 7991 is commonly used in applications where a smooth finish is required, including machinery, aerospace, automotive, and furniture assembly, as they provide a clean and unobtrusive appearance.
