Machine Tap Form B HSSE VAP - UNC 3/8 x 16

• for machine-guided internal thread cutting
• for UNC 3/8 x 16 when the stated thread system, size, and pitch match the drawing
• for through holes
• 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 Check form, thread direction, holder setup, and hole type before starting the tapping operation.

• HSSE VAP is stated in the product data and supports professional machine tapping when the setup is correct.
• The tool form gives a defined choice for through holes.
• The thread designation UNC 3/8 x 16 reduces selection errors between similar inch or metric threads.
• Machine-tap geometry supports repeatable thread production in guided processes.

• A machine tap requires correct alignment, feed, and holder setup, so use a hand tap sequence when a controlled manual process is required.

1. Confirm that UNC 3/8 x 16 matches the workpiece drawing and thread direction.
2. Check that the tap form is suitable for through holes.
3. Clamp the tap in a suitable machine holder or guided fixture.
4. Align the tool with the hole axis before starting the cut.
5. Set feed, speed, and lubrication according to the material and machine setup.
6. Cut the thread without forcing the tool beyond the intended depth.
7. Remove chips and cutting fluid residue after tapping.
8. Inspect the thread before assembly or further processing.

Which hole type is this tap intended for?

The tap form in the product data points to through holes, so match the form to the workpiece before use.

How do you select the correct thread?

Match UNC 3/8 x 16 exactly, including thread family, size, pitch or threads per inch, and thread direction.

Can a left-hand tap replace a right-hand tap?

No, left-hand and right-hand taps are not interchangeable because the thread direction is different.

What setup is required?

Use a suitable machine holder or guided fixture with correct alignment, feed, speed, and lubrication.

When should you use a hand tap instead?

Use a hand tap sequence when the operation requires controlled manual cutting rather than a machine-guided process.
