Countersunk Allen screw DIN 7991 M6x30-10.9 galvanized

Product detailed description

The DIN 7991 M6x30-10.9 zinc-plated countersunk head screw is a high-quality fastener designed for demanding metal and structural applications. This screw is made of 10.9 strength grade steel, which ensures its high strength and resistance to mechanical stress. The zinc-plated surface treatment provides corrosion protection, extending the life of the screw in various environments.

The screw has a metric thread with a diameter of M6 and a length of 30 mm, with a thread pitch of 1.00 mm. The 90° countersunk head allows the screw to be flush with the surface of the material after tightening, thus achieving a smooth joint surface. The 4 mm internal hexagon allows for efficient torque transmission when installing using an Allen key.

The DIN 7991, ISO 10642 and ČSN 021144 standards define the exact dimensions and tolerances that this screw meets. The head diameter is 12 mm, the head height is 3.7 mm and the countersunk height is 2.5 mm. These parameters ensure a reliable and strong connection, ideal for applications where an aesthetic appearance and minimal height above the surface are required.

This screw is suitable for use in various industrial sectors where it is necessary to ensure a strong and reliable connection with an emphasis on aesthetics and functionality.
