Frequently Asked Questions

What is the OSG Thread Forming Tap #12-28 UNF used for?

The OSG Thread Forming Tap #12-28 UNF is used to create internal threads in metal workpieces without cutting material, reducing chip buildup. It is ideal for ductile materials like aluminum, steel, and stainless steel in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG Thread Forming Tap 1400124901?

The OSG Thread Forming Tap has a #12-28 UNF thread size, H4 / 2B-3B tolerance, plug chamfer, and black oxide cobalt finish. It is designed for general-purpose thread forming in materials up to 850 °C hardness, with a manufacturer part number 1400124901.

Where to buy OSG Thread Forming Tap #12-28 UNF worldwide?

You can source the OSG Thread Forming Tap #12-28 UNF worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location, ensuring reliable supply for your manufacturing needs.

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

To select the correct OSG Thread Forming Tap, match the thread size (#12-28 UNF) and tolerance (H4 / 2B-3B) to your workpiece material and hole requirements. Use a plug chamfer for through holes and ensure the tap is suitable for ductile materials to avoid breakage.
