Cleveland C54165 Straight Flute Hand Tap

The Cleveland C54165 is a straight flute hand tap designed for creating M3x0.5 metric threads in through-holes or blind holes. It suits maintenance technicians, hobbyists and light-production workshops that cut internal threads by hand or with a tapping head.

Plug chamfer and 75 percent thread engagement

The plug chamfer provides a moderate lead-in that starts threads easily while leaving enough full-form threads for engagement. Drill the hole to 2.50 mm to achieve the specified 75 percent thread depth; the thread length is 7.87 mm within an overall length of 49.28 mm.

Thread limit D3 and 6H class of fit

The tap is manufactured to a D3 thread limit for a 6H class of fit, which determines the allowance and tolerance of the finished thread. Select this tap only when the drawing or specification calls for a 6H internal thread; a tighter or looser class requires a different limit.

Questions about this item

Which thread size and pitch should I select for an M3 hole?

The tap is cut for M3 × 0.5 metric threads, the standard coarse pitch for a 3 mm diameter.

What does the 75 percent thread drill size of 2.50 mm mean when I am tapping?

Drill the hole to 2.50 mm before tapping; that diameter produces roughly 75 percent thread engagement for a strong fit.

How does the D3 thread limit affect the class of fit in practice?

D3 places the pitch diameter near the middle of the 6H tolerance zone, giving a standard medium fit for general-purpose assemblies.
