STI HexTap for oil drain screw threads HSS-G - M 20 x 1.5

• Supporting practical threading work where correct tool assignment matters before the operation starts
• Using the product in workshop, maintenance and production support environments
• Selecting the relevant thread system and drive concept before use
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: thread cutting, re tapping, and thread cleaning depending on condition

Note Select the product by thread designation, workpiece condition and the holder concept used in your process.

• Thread related geometry and designation are clearly assigned in the product name for practical selection
• Suitable for workshop, maintenance and machine room workflows with repeatable tool use
• The explicit standard and material markings support controlled tool assignment in professional use
• A dedicated threading tool reduces compromise compared with improvised general purpose tooling

• Tool selection still depends on matching the thread system, material and process type to the actual job.
• It is intended for defined threading work and not for undirected high speed use without the correct setup and lubrication strategy.

1. Prepare the core hole and secure the workpiece so the tool can enter on axis.
2. Clamp the STI tap in a suitable holder or drive with secure torque transmission.
3. Align the tap square to the hole entry and start the cut with controlled feed.
4. Advance the tap according to your process while keeping lubrication and alignment stable.
5. Reverse and remove the tap carefully once the receiving thread is completed.
6. Clean the thread and check it before insert installation begins.
