WIDIA GTD Thread Forming Tap: 1/4"-20 UNC, H4 / 2B-3B

A WIDIA GTD thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger threads with no chips. It is ideal for ductile materials like aluminum, brass, and low-carbon steel in automotive, aerospace, and general machining applications.

The WIDIA GTD 19869 is a 1/4"-20 UNC thread forming tap with an H4 / 2B-3B tolerance class and a bottoming chamfer. It is designed for general purpose use and produces threads that meet 2B or 3B fit requirements in ductile materials.

3G Electric supplies WIDIA GTD thread forming taps worldwide, handling full logistics and customs clearance for international orders. As a global industrial solutions provider, we source genuine WIDIA GTD taps like the 19869 and deliver them to your facility, regardless of location.

Select a thread forming tap based on material type, thread size, and tolerance class. For ductile materials like aluminum or brass, use a forming tap with the correct UNC or UNF designation and chamfer type. The WIDIA GTD 19869 with H4 / 2B-3B tolerance suits general purpose threading in softer metals.
