(high-strength m36 stud bolt specifications and)
High-strength M36 stud bolts represent the pinnacle of industrial fastening technology, designed to withstand axial loads up to 1,450 MPa while maintaining dimensional stability within ±0.05 mm tolerance. These dual-threaded fasteners comply with ASME B16.5 and ISO 898-1 standards, featuring:
Advanced metallurgical formulations differentiate premium-grade stud bolts from conventional fasteners. Our M36 bolts utilize ASTM A193 B7M alloy steel, achieving:
Property | B7M | Standard B7 | 2H Grade |
---|---|---|---|
Yield Strength | 895 MPa | 725 MPa | 940 MPa |
Stress Rupture (550°C) | 220 MPa | 180 MPa | 240 MPa |
Corrosion Resistance | 3.2 mm/Year | 4.7 mm/Year | 2.8 mm/Year |
Third-party testing confirms a 28% improvement in fatigue life compared to standard B7 stud bolts when subjected to cyclic loading at 80% of yield strength. Key benefits include:

A: High-strength M36 stud bolts typically meet ASTM A193/A193M standards, feature a diameter of 36mm, and are designed for extreme tensile stress (up to 120 ksi). They are heat-treated for enhanced durability in industrial applications.
A: B7 stud bolts are made from alloy steel (ASTM A193) and heat-treated to achieve high tensile strength (minimum 125 ksi). They outperform standard bolts in high-temperature/pressure environments like oil refineries.
A: 2H grade fasteners (ASTM A490) are ideal for structural steel connections requiring shear strength, such as bridges, heavy machinery, and seismic-resistant building frameworks.
A: No—B7 bolts excel in thermal/chemical resistance for pipelines, while 2H grade is optimized for structural steel shear loads. Material and coating requirements also differ between applications.
A: M6 self-tapping screws feature hardened steel construction (up to 1,000 MPa tensile strength), sharp threads for material penetration, and corrosion-resistant coatings like zinc plating for outdoor use.
