Jack Bolt

JackboltSuite - Industrial Jackbolt Calculator

The essential jackbolt calculation tool for mechanical engineers, maintenance technicians, and industrial professionals working with multi-jackbolt tensioners (MJT), Superbolt-type tensioners, and flange bolting systems.

WHY JACKBOLTSUITE?

• Fast, accurate calculations without complex spreadsheets
• Works completely offline - perfect for plant and field use
• Based on ASME B18.2.2 Heavy Hex Nuts & ANSI/ASME B18.2.1 Heavy Hex Bolts standards
• Designed by engineers, for engineers

POSITION CALCULATOR

Calculate optimal jackbolt placement around stud bolts:
• BCD (Bolt Circle Diameter) optimization with automatic interference detection
• Jackbolt angular position calculation for 1, 2, or 4 jackbolts per stud
• Stud-to-jackbolt clearance verification
• Real-time visual diagram showing bolt arrangement
• Prevents costly assembly errors and rework

LENGTH CALCULATOR

Determine the correct jackbolt length for your application:
• Input flange thickness, nut height, and engagement depth
• Automatic calculation based on bolt specifications
• Accounts for standard tolerance and safety margins
• Results rounded to standard bolt lengths

IDEAL FOR

• Power plant maintenance and turnaround projects
• Refinery and petrochemical facility bolting
• Pipeline flange assembly and maintenance
• Pressure vessel and heat exchanger servicing
• Wind turbine foundation bolting
• Heavy equipment assembly
• Industrial machinery installation
