Description by David May Written by the developer, not by AppBrain. Click to read.
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.
