One address reaches this site: h87936622@gmail.com. It is a single mailbox, read by the operator, so replies take a few days.

What to send

• Corrections. A torque or weight figure that has drifted from the manufacturer's page, or a chart row that disagrees with the standard it cites. A link to the source speeds it up.
• Questions about the charts. If a recommended pilot hole or RPM looks wrong for your material, say which row you were reading.
• Table suggestions. A drill worth adding to the comparison, or a fastener chart that is missing: model or standard name and, if you have it, the official spec page.

What not to expect

No phone line, no postal address, no contact form, no newsletter to sign up for. Email is the whole channel, and there is no press kit because there is no press operation.
