High-Strength M36 Stud Bolt Specifications and Engineering Requirements

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:

  • Nominal diameter: 36 mm ±0.2 mm
  • Thread pitch: 4 mm (coarse) or 3 mm (fine)
  • Minimum tensile strength: 1,040 MPa
  • Surface hardness: 32–38 HRC

Material Composition and Manufacturing Standards

Advanced metallurgical formulations differentiate premium-grade stud bolts from conventional fasteners. Our M36 bolts utilize ASTM A193 B7M alloy steel, achieving:

PropertyB7MStandard B72H Grade
Yield Strength895 MPa725 MPa940 MPa
Stress Rupture (550°C)220 MPa180 MPa240 MPa
Corrosion Resistance3.2 mm/Year4.7 mm/Year2.8 mm/Year

Performance Advantages Over Competing Industrial Fasteners

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:

  • Reduced relaxation rate: 0.12% per 1,000 hours vs. 0.35% for ASTM A320
  • Enhanced galling resistance through proprietary PTFE coating
  • EMBEDDED RFID tags for traceability in ISO 9001 systems

FAQS on high-strength m36 stud bolt specifications and

Q: What are the key specifications of high-strength M36 stud bolts?

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.

Q: How does a B7 stud bolt differ from standard stud bolts?

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.

Q: What applications suit 2H grade high-strength industrial fasteners?

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.

Q: Can B7 and 2H grade bolts be used interchangeably?

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.

Q: What makes M6 high-strength self-tapping screws secure?

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.
