Field Torque Calculator for Bolted Joints
Built for Installers, and Engineers.
This simple, practical tool eliminates the need for bulky torque charts or overly complicated apps. Whether you're working on-site, in a plant, or in the field, just select your bolt size and grade — and get a reliable torque estimate instantly.
Why this app is different:
• Designed specifically for installers — not engineers
• Only the inputs you actually know in the field
• No fluff, no overcomplicated formulas, no unnecessary steps
• Instant torque estimates based on industry-standard formulas
Features:
• Select bolt thread size and grade
• Adjust K-factor and tightening percentage
• Outputs torque required to reach target clamp load
• Works offline — perfect for job sites with no signal
This app helps you get it right the first time, every time.
