OSG Thread Forming Tap: 3/8"-16 UNC, H12, Plug Chamfer

An OSG 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, steel, and stainless steel in automotive, aerospace, and general manufacturing applications.

This OSG tap has a 3/8"-16 UNC thread size, H12 tolerance, plug chamfer, and black oxide cobalt finish. The H12 class provides a slightly oversized thread for applications requiring tighter fit or coating allowance. The cobalt material enhances heat resistance and tool life.

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine OSG taps like the 3/8"-16 UNC H12 model to customers across 14 departments, including machining and tooling.

Select based on thread size (e.g., 3/8"-16 UNC), material type, and tolerance class (H12 for oversized threads). Use a forming tap only for ductile materials that can flow, not brittle ones. Ensure proper lubrication and hole size per OSG recommendations to avoid tap breakage.
