uxcell Metric Hand Threading Tap Set M2

Overview

M2 x 0.4 is a small metric thread pitch used in electronics, model making and instrument repair, and it is the size this uxcell tap is ground to cut. High speed steel construction and a light 0.81 ounce weight round out the only specs on file, both consistent with a small hand operated tap.

Fine threads like M2 x 0.4 leave little room for error, so the tap doing the cutting needs to hold an edge without wandering. High speed steel gives it the hardness for that at this small a diameter, where a broken tap can be difficult to remove from the workpiece.

• Brand: uxcell
• Material: high speed steel
• Size: M2 x 0.4
• Weight: 0.81 ounces

Who it's for

Suits hobbyists, electronics repair work and small mechanical projects that call for an M2 x 0.4 thread specifically. Not useful for anyone needing a different thread size, since a tap only cuts the single size it is ground for.

Pros and cons

Performance notes

Cutting a clean M2 x 0.4 thread at this scale calls for a hard, accurate edge, which is what high speed steel construction is meant to deliver. At 0.81 ounces the tap is sized to be turned by hand with a tap wrench rather than driven by a power tool.
