Countersunk Allen screw DIN 7991 M16x40-10.9 galvanized

Product detailed description

The countersunk head screw with internal hexagon according to DIN 7991, ISO 10642 and ČSN 021144 is intended for applications where a flat surface of the joint is required. This screw has a metric thread M16 with a length of 40 mm and a pitch of 2.00 mm. The head of the screw is countersunk with an angle of 90°, which allows it to be embedded in the material so that it is flush with the surface. The head diameter is 30 mm, the head height is 5.3 mm and the width of the internal hexagon is 10 mm.

The screw is made of steel of strength class 10.9, which means that it has a high tensile strength and is suitable for demanding structural applications where high reliability and resistance to mechanical stress are required. The zinc coating provides corrosion protection, which extends the life of the screw in environments with higher humidity or chemical aggressiveness.

This type of screw is ideal for use in metal structures, engineering and other industries where it is necessary to ensure a strong and reliable connection. The internal hexagon allows for easy assembly and disassembly using an Allen key, which increases the efficiency of assembly work. The screw is suitable for applications where aesthetic appearance and minimal protrusion above the surface of the connected material are important.
