Cleveland C54814 Hand Tap

The Cleveland C54814 is a straight-flute hand tap designed to cut internal threads in a single pass. Made from high-speed steel with a bright uncoated finish, it features a right-hand 11/16"-11 UNS thread form and a plug chamfer for general-purpose threading.

Suitable Applications

This tap suits machinists and maintenance technicians who need to create or repair 11/16"-11 UNS class 2B threads in materials such as steel or cast iron. It is not for buyers who require a spiral-point or spiral-flute tap for blind-hole chip evacuation or for high-volume production tapping.

Critical Specification

The thread limit is H3, which determines the pitch-diameter tolerance and the resulting class of fit. Verify that H3 matches the engineering requirement for the specific assembly before purchasing.

Questions about this item

How can I verify the 11/16"-11 UNS tap cuts a correct 2B class thread after setup?

Cut a test hole in scrap material then check the thread with an 11/16"-11 UNS 2B go/no-go gauge; the go gauge should enter fully and the no-go gauge should stop within three turns.

What comes in the box with the Cleveland C54814 and what must I supply separately?

The box contains the 4.03 in overall length high-speed steel straight flute tap with 1.81 in thread length; you must supply a tap wrench or powered driver, cutting fluid, drill bit for the tap drill size and a thread gauge.

When should I choose the H3 thread limit version of this 11/16"-11 tap over other limits?

Select the H3 limit when the application requires a standard 2B class of fit for general-purpose unified threads; tighter H limits produce a tighter fit while looser limits give more clearance.
