The M10X40 flat-head Allen hardened screw, manufactured according to DIN 7991, has a nominal diameter of 10 millimeters and a length of 40 millimeters, suitable for fastening medium to heavy industrial components. Its thread pitch is 1.5 millimeters with a thread depth of approximately 1 millimeter, ensuring uniform engagement and stress-free load transfer. The unit weight is around 0.085 kilograms per 10 centimeters of length, allowing precise calculation of total assembly weight and structural load analysis. The flat-head design with an Allen socket enables flush installation in countersunk holes, providing even pressure distribution and a clean, uniform connection surface.

This screw is made of hardened carbon steel with heat treatment, providing high wear resistance for repeated assembly and disassembly without thread deformation. Its thermal resistance is stable up to 200°C, and surface hardness ranges between 200–220 HV, ensuring long-term durability and performance in industrial environments. Precision-machined threads and dimensional uniformity according to DIN 7991 guarantee consistent mechanical performance and secure fastening in machinery, industrial equipment, and metal structures. This screw is ideal for applications requiring high load capacity and variable environmental conditions.
