Product Description

The M8x12 hex socket screws, also known as DIN 912 M8x12 screws, feature a cylindrical head design for low-profile fastening in confined spaces. These cylindrical head hex screws are manufactured to DIN 912 standards with an 8mm diameter and 12mm length, using grade 8.8 steel or A2/A4 stainless steel options. Suitable for industrial applications including machinery assembly, automotive components, and electronic enclosures, they provide high shear strength and vibration resistance. The internal hex drive (Allen key) enables precise torque control up to 24Nm (steel variants) while maintaining a flush surface. Surface treatments include zinc plating for corrosion protection or plain finish for indoor use. Installation requires a 6mm hex key and operates within standard industrial temperature ranges (-30°C to +120°C). Advantages include space efficiency and durability, though accessibility limitations may occur in deep recesses.
