• Grade 8.8 & 10.9 Bolts Manufacturer Stud EN 15048

    Astech Tube is a leading manufacturer of EN 15048 Studs producing high-quality Grade 8.8  10.9 Stud Bolts. These bolts are one of the important structure parts whose strength and toughness are both superior in structural applications. Grade 8.8 bolts are austenitic medium carbon steel with high tensile strength, so suitable for heavy work. Grade 10.9 Stud Bolts are made from alloy steel and heat-treated to improve mechanical properties for high-load environments. With years of expertise, As a leading EN 15048 Fasteners Supplier we ensure to deliver excellence in every product.

    Grade 8.8 Stud Bolts possess mechanical characteristics of minimum yield strength of 640MPa to 660MPa and a tensile strength of 800 MPa to 830 MPa. High Strength Studs EN 15048 are produced in sizes 20mm to 380mm length with various surface treatments such as zinc plated, plain or hot-dip galvanized. According to ASTM A574 and ASTM A574M specifications, the bolts are produced in sizes of 16mm to 72mm to fit different structural applications. For Grade 10.9 Stud Bolts, the mechanical properties include a minimum yield strength of 940 MPa and a tensile strength of 1040 MPa. Available in diameters from M20 to M100 (or 3/4" to 3.1/2"), these bolts meet ASTM A324 and ASME SA324 standards. Their exceptional strength-to-weight ratio makes them the preferred choice for heavy-duty applications.
