Hex socket countersunk head screws are mechanical fasteners with a conical head and internal hex drive, designed to provide flush surface installation and uniform load distribution. They are typically made from alloy steel, carbon steel, or stainless steel with surface hardness of 250–400 HB and tensile strength of 800–1200 MPa. Screw diameters generally range from M3 to M20, with lengths from 6 to 150 mm. The countersunk head angle is typically 90 degrees, allowing full seating within the component surface. Threads are manufactured according to ISO or DIN standards, enabling high torque transmission.
Hex socket countersunk head screws are used in industrial machinery, precision equipment, mechanical components, and metal structures. The countersunk design reduces surface protrusion, improves safety, and enhances moving part performance. Surface treatments such as galvanization, black oxide, or chrome increase corrosion and wear resistance. Manufacturing according to industrial standards ensures durable connections, reduced loosening, and extended service life.You can order and buy Socket Hex CSK Screw from Iran by contacting us through whatsaap and email.

Types of Allen Bolts with Hexagonal Heads and Standard Sizes in iran
Allen bolts with hexagonal heads are divided into two standard types: standard Allen bolts and countersunk Allen bolts. The standard Allen bolt DIN 912 is used for connecting components in industrial machinery and precision tools, offering high tensile strength. The countersunk Allen bolt DIN 7991 has a flat head, ideal for limited spaces or applications where a flush surface is needed. Standard Allen bolt sizes range from M3 to M20, with lengths from 6 to 100 mm. These bolts are typically made from carbon steel or stainless steel and are available in grades 8.8, 10.9, and 12.9.
