Bolt Torque Helper is an offline utility designed for repair technicians, equipment assembly, machining, and DIY users. It focuses on bolt specifications, torque unit conversion, and assembly records, helping you quickly check reference torque values on site and reduce time spent searching tables or calculating by hand. Key features: 1. Bolt torque reference: look up suggested torque ranges by metric size, strength grade, and lubrication condition. 2. Torque unit conversion: convert between common units such as N·m, kgf·cm, lbf·ft, and lbf·in. 3. Assembly records: create local records for equipment, position, bolt size, target torque, and completion status. 4. Tightening checklists: check off multiple bolts by project, with review time and notes. 5. Reusable templates: save torque templates for common equipment or workstations and reuse them for repeated jobs. All data is stored only on your device. No login, no network connection, and no personal data collection are required.
