Frequently Asked Questions
What is an OSG thread forming tap used for?
An OSG thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger threads in ductile materials like aluminum, brass, and low-carbon steel. It is ideal for applications requiring chip-free threading, such as automotive and aerospace manufacturing.
What are the specifications of the OSG 1/4"-20 UNC thread forming tap?
This OSG tap has a 1/4"-20 UNC thread size, H3 / 2B-3B tolerance, plug chamfer, and TiN coating on cobalt steel. The TiN coating reduces friction and extends tool life. It is designed for general-purpose thread forming in materials up to 850 °C hardness.
Where to buy OSG thread forming taps worldwide?
3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source genuine OSG tools like the 1/4"-20 UNC TiN-coated tap (MPN 1400127005) and deliver to your facility with complete documentation.
How to select the right thread forming tap for your application?
Select a thread forming tap based on material type, thread size, and tolerance class. For ductile materials like aluminum, use a TiN-coated tap like this OSG 1/4"-20 UNC with H3 / 2B-3B tolerance. Ensure the tap chamfer matches your hole depth—plug chamfer suits general blind-hole threading.
