Countersunk Allen screw DIN 7991 M16x90 stainless steel A2

Product detailed description

The countersunk hexagon socket head cap screw according to DIN 7991 and ISO 10642, made of stainless steel grade A2, is designed for applications requiring precise fit and high preload. This screw has a metric thread with a diameter of M16 and a total length of 90 mm. The partial thread with a length of 44 mm and a pitch of 2.00 mm allows for optimal distribution of forces in the joint.

The head of the screw is countersunk with a hexagon socket, which allows it to be embedded in the material, thus achieving a smooth surface without protruding parts. The head diameter is 30 mm, the head height is 5.3 mm and the countersunk head angle is 90°, which guarantees a precise and firm seat in the material. The width of the internal hexagon is 10 mm, which ensures reliable torque transmission during assembly.

The A2 stainless steel material provides high corrosion resistance, which is ideal for use in environments with higher humidity or chemical exposure. The screw has no surface treatment, which is typical of stainless steel materials that naturally resist corrosion.

This screw is suitable for use in mechanical engineering, construction and other technical areas where a reliable and aesthetically unobtrusive connection is required. The ČSN 021144 and ISO 10642 standards guarantee compatibility and product quality according to international standards.
