OSG Thread Forming Tap: 1/4"-28 UNF, H6 / 2B-3B, Plug Chamfer

An OSG thread forming tap creates internal threads by displacing material rather than cutting it. It is used in ductile materials like aluminum, brass, and low-carbon steel to produce stronger, burr-free threads with no chips. This 1/4"-28 UNF plug-chamfer tap is ideal for through-hole applications in general manufacturing.

This OSG tap has a 1/4"-28 UNF thread size with an H6 / 2B-3B tolerance class, plug chamfer, and black oxide cobalt finish. The black oxide coating reduces friction and improves wear resistance. It is designed for general-purpose thread forming in ductile materials and is identified by MPN 1400129501.

Select an OSG thread forming tap based on thread size, pitch, tolerance class (e.g., H6 / 2B-3B), and chamfer type. Plug chamfer is standard for through holes. Ensure the workpiece material is ductile enough for forming (e.g., aluminum, brass, mild steel). Use proper lubrication and tap speed per OSG recommendations for best thread quality.
