Cleveland C54029 Hand Tap 0-80 Unf Plug Hss Bright

Product Description

The CLEVELAND C54029 is a 0-80 UNF plug chamfer hand tap designed for cutting internal threads in a range of metallic workpieces. Built from high speed steel with a bright uncoated finish, this tap produces right-hand threads to a Class 2B fit with an H2 thread limit. The straight two-flute design provides reliable chip clearance in both blind hole and through-hole threading applications. Overall length is 1.625 inches, with a thread length of 0.31 inches, making it well suited to tight, precise work in small-diameter threading jobs. Licensed machinists, tool and die makers, and maintenance technicians are the typical users.

This tap is intended for hand tapping operations on small fastener threads at the 0-80 size, which is common in instrument manufacturing, electronics assembly, optical equipment, and precision mechanical assemblies. The plug chamfer — typically 3 to 5 threads of taper — allows starting in either a through hole or a blind hole where adequate thread depth permits entry. It is part of the Cleveland Series 1002 and is sold individually.

Key Features

• High speed steel construction for durability across a range of metals
• Bright uncoated finish suitable for general-purpose threading without coating buildup concerns
• Plug chamfer for versatile use in blind hole and through-hole applications
• Class 2B fit with H2 thread limit for standard UNF thread tolerances
• Two-flute straight flute design for controlled chip ejection during hand tapping
• Right-hand thread direction, standard for UNF fastener applications

Compatibility

Compatible with alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces. Designed as a standard hand tap replacement for 0-80 UNF internal threading in Series 1002 applications.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard tap wrench sized for the shank diameter. Before tapping, verify the pilot hole diameter matches the recommended tap drill size for 0-80 UNF threads and that the workpiece is securely fixtured. Apply appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Avoid excessive force during engagement to prevent tap breakage, particularly in hard or abrasive alloys.
