Cleveland C54193 Hand Tap 5-44 Unf Plug 3-flute Hss

Product Description

The CLEVELAND C54193 is a 5-44 UNF plug chamfer hand tap machined from high speed steel with a bright uncoated finish. Designed for right-hand threading, this 3-flute straight flute tap cuts clean internal threads in both blind holes and through-holes. The plug chamfer style — with a moderate lead — suits most general-purpose tapping operations where thread engagement is established partway through the workpiece. Overall length is 1.938 inches with a thread length of 0.31 inches, making it well suited for compact fastener applications common in precision assembly and light manufacturing. The H2 thread limit holds tight tolerances for a 2B class of fit.

This tap is intended for use in machine shops, maintenance environments, and production settings where 5-44 UNF internal threads are required. The straight flute geometry works reliably in both blind hole and through-hole configurations. It is appropriate for use in hand-tapping setups or low-speed machine tapping operations where chip management is controlled manually or by the operator. The Series 1002 designation places this tap within Cleveland's standard catalog line for inch-series UNF applications.

Key Features

• 5-44 UNF thread form with right-hand cutting direction
• Plug chamfer entry for general-purpose blind and through-hole tapping
• 3-flute straight flute design for controlled chip formation
• High speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish — no coating buildup to affect thread tolerance
• H2 thread limit maintains 2B class of fit for standard fastener compatibility

Compatibility

Suitable for tapping alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces requiring 5-44 UNF internal threads.

Installation Notes

Hand taps should be installed using a properly sized tap wrench or held in a rigid tapping fixture when used with a machine. Secure the workpiece firmly before tapping to prevent thread misalignment. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread finish. Follow standard shop safety practices and ensure the tap is correctly aligned with the pilot hole before applying torque.
