Fastener Tools & Calculators
Measure first. Diagnose clearly. Repair with less guesswork.
Use the workbench tools to narrow a fastener problem, check a dimension or choose a sensible repair path. Every result is a starting point—not a substitute for the exact manufacturer procedure on a critical joint.
Choose the question you need to answer
Do not start with a product. Start with the failure, the measurement or the repair decision you actually need to make.
Fastener Problem Solver
Start with the symptom and work toward the least destructive sensible repair.
Thread Identifier
Use measured diameter and pitch to narrow down a likely thread specification.
Thread Repair Selector
Match the type of thread damage and parent material to an appropriate repair path.
Tap Drill Calculator
Calculate a practical starting drill size for common cutting taps, then verify against the tap manufacturer or chart.
Metric / Imperial Converter
Convert fastener dimensions between millimeters and inches.
Tool result → verification → repair guide
Use the symptom or measurement to reduce the number of plausible paths.
Confirm pitch, material, access, load and the exact system requirements before committing.
