Cleveland C54865 Straight Flute Hand Tap

The Cleveland C54865 is a straight flute hand tap designed for creating internal threads in metric sizes. It is intended for manual threading operations in maintenance, repair and light production environments where machine tapping is not available.

Suited for mechanics and fabricators cutting M20 x

This tap suits users who need a plug-style entry for through-holes or deep blind holes in steel and similar materials. It is not for buyers requiring a bottoming chamfer for shallow blind holes, nor for high-volume CNC tapping where spiral-point or spiral-flute geometries are needed.

M20 x 2.5 thread with 50.8 mm thread length

The D7 limit and 6H class of fit provide standard tolerance for general-purpose fastening. The 75 percent thread drill size of 17.50 mm ensures proper engagement. The 13.51 mm overall length limits reach in deep or recessed holes, so users needing extended reach should consider alternative tooling.

Questions about this item

What size drill bit do I need to prepare the hole before using this M20x2.50 tap?

Use a 17.50 mm drill bit to create the 75 percent thread hole required for this M20x2.50 tap.

Will this M20x2.50 tap fit the thread pitch of older metric fasteners I have in stock?

This tap cuts a 2.50 mm pitch thread; it matches older M20 fasteners only if they share the same 2.50 mm pitch.

How can I confirm the threads I cut with this tap meet the 6H class of fit?

Check the finished threads with an M20x2.50 6H thread gauge; a proper Go/No-Go fit confirms the D7 limit is met.
