Cleveland C54600 Straight Flute Hand Tap
The Cleveland C54600 is a straight flute hand tap designed for cutting internal threads in a variety of materials. It suits mechanics, machinists and maintenance technicians who need to create precise 3/8"-24 UNF threads by hand. The high-speed steel construction provides durability for general-purpose threading tasks in workshop and automotive environments.
3/8"-24 UNF thread capacity and H3 limits
This tap cuts a 3/8"-24 UNF thread with a thread length of 1 1/4 in and an overall length of 2 15/16 in. The H3 thread limit and Class 3B fit deliver accurate threads for standard fastening applications. It requires a 75 percent thread drill size of 8.50 mm for proper hole preparation. The four-flute design aids chip evacuation but may struggle in very deep or blind holes where chip clearance is limited.
Bright uncoated high-speed steel finish
The tap features a bright, uncoated high-speed steel surface without any protective coating. This finish is suitable for general machining in low-alloy steels and non-ferrous metals. It lacks surface treatments that extend tool life in abrasive or high-heat materials such as stainless steel or titanium. Buyers needing enhanced wear resistance or lubricity for difficult alloys should consider coated alternatives.

Questions about this item
Will the 3/8"-24 UNF tap fit the existing threads on my older pneumatic fittings?
The tap cuts right-hand UNF threads to a 3B class of fit with an H3 limit, matching the standard 3/8"-24 specification used on many legacy pneumatic components.
How can I verify the tap is cutting correctly once I start using it?
Check that the threads measure to the 3B class of fit and that the 75 percent thread depth matches the 8.50 mm drill size used for the pilot hole.
Does the kit include the 8.50 mm drill bit needed for the 75 percent thread depth?
The three-piece tap kit contains taper, plug and bottoming taps only; the 8.50 mm drill bit must be purchased separately.
