Frequently Asked Questions

What is the OSG Thread Forming Tap 1/4"-28 UNF used for?

The OSG Thread Forming Tap 1/4"-28 UNF is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting chips. It is ideal for automotive, aerospace, and general manufacturing applications requiring strong, burr-free threads.

What are the specifications of the OSG Thread Forming Tap 1400129205?

The OSG Thread Forming Tap 1400129205 has a 1/4"-28 UNF thread size, H3 / 2B-3B tolerance, plug chamfer, and TiN coated cobalt construction. It is designed for general purpose thread forming in materials up to 850 °C hardness, ensuring long tool life.

Where to buy OSG Thread Forming Tap 1/4"-28 UNF worldwide?

You can source the OSG Thread Forming Tap 1/4"-28 UNF worldwide through 3G Electric, a global industrial equipment distributor since 1990. We handle full logistics, customs clearance, and delivery to your location, ensuring reliable supply for your operations.

How to select the correct OSG Thread Forming Tap for my application?

To select the correct OSG Thread Forming Tap, match the thread size (e.g., 1/4"-28 UNF) and tolerance class (H3 / 2B-3B) to your workpiece material and hole preparation. Use a plug chamfer for through holes and ensure the tap is suitable for the material hardness, typically below 850 °C.
