Thread size and purpose
This Cleveland straight-flute hand tap cuts 5/8"-11 UNC threads in a right-hand direction. It is made from high-speed steel with a bright uncoated finish and suits general-purpose threading tasks in workshop or maintenance environments.
Hole preparation required
The tap needs a 13.60 mm drill hole to produce a 75 percent thread depth for a 2B class of fit. The thread length is 1.81 in within an overall length of 3.81 in, so the workpiece must accommodate that reach and the bottoming chamfer style.
Material and daily use
High-speed steel construction resists wear during repeated hand-tapping operations. The uncoated bright surface allows easy inspection of cutting edges, while the straight-flute design clears chips effectively in through-holes or blind holes when turned manually.

Questions about this item
Does the tap come with a handle or drill bit, or must I buy them separately?
The package contains only the straight-flute tap itself; a tap wrench or suitable holder and a 13.60 mm drill bit for the 75 percent thread depth are sold separately.
When should I choose the bottoming version instead of a taper or plug tap?
Choose this bottoming tap when you need to cut threads close to the bottom of a blind hole, as its short chamfer starts threading with minimal lead-in.
What does the H3 thread limit mean for the finished 5/8"-11 UNC hole?
The H3 limit produces a Class 2B fit, giving a standard allowance and tolerance for general-purpose fastening in steel or similar materials.
