Frequently Asked Questions

What is the CHICAGO-LATROBE Spiral Point Tap #6-40 UNF used for?

This tap is used for threading #6-40 UNF holes in production and maintenance applications. Its spiral-point design pushes chips forward, making it ideal for through-hole threading in materials like steel and aluminum. It is commonly used in automotive, aerospace, and general manufacturing where precise internal threads are required.

What are the specifications of the CHICAGO-LATROBE Spiral Point Tap 356548?

The CHICAGO-LATROBE Spiral Point Tap (MPN 356548) is a #6-40 UNF tap with H2 / 2B tolerance, 2 flutes, and a plug chamfer. It is made from high-speed steel (HSS) for durability. This general-purpose tap is designed for through-hole threading and provides efficient chip evacuation.

Where to buy CHICAGO-LATROBE taps in worldwide?

You can source CHICAGO-LATROBE taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead times on the #6-40 UNF spiral point tap (MPN 356548) and other CHICAGO-LATROBE tooling.

How to select the right CHICAGO-LATROBE tap for a job?

Select a tap based on thread size, material, and hole type. For through holes, a spiral point tap like the CHICAGO-LATROBE #6-40 UNF pushes chips ahead. For blind holes, use a spiral flute tap. Match the tap tolerance (e.g., H2 / 2B) to your required thread class. Always use proper cutting fluid for the workpiece material.
