Estimate the tapping drill diameter for common metric threads.
This is a general planning estimate. Check units and verify critical results independently.
Engineering results depend on inputs, assumptions and real-world conditions. Use this as a planning/checking value and verify critical work against manufacturer data, drawings or applicable standards. How our calculations work →
Estimate the tapping drill diameter for common metric threads. Enter the requested values, calculate the result, then compare it with drawings, catalogues, standards or manufacturer information relevant to the job.
Estimate the tapping drill diameter for common metric threads.
No. The formula provides an engineering estimate based on the inputs and assumptions shown. Real systems can include tolerances, friction, losses, material variation and regulatory requirements.
Estimate bolt tightening torque from preload, nominal diameter and nut factor.
FastenersLook up close, normal and loose metric bolt clearance-hole sizes.
FastenersConvert threads per inch to metric pitch, or metric pitch to TPI.
