Value Collection 20A010CP 10-24 Unc 4FL Hss Bottom Tap

Product Description

The VALUE COLLECTION 20A010CP is a straight flute hand tap designed for cutting internal threads in through-holes and blind holes requiring a bottom thread chamfer. Built from high-speed steel (HSS), it is engineered to produce clean, accurate 10-24 UNC threads with a 4-flute straight flute geometry. The bottom chamfer style allows threading close to the bottom of a blind hole, making it the correct choice when full thread depth is required to the base of the bore. This tap is suited for use in a variety of materials including mild steel, aluminum, brass, and plastics.

This tap is used in machine shops, maintenance and repair operations, and field service applications where 10-24 UNC threaded holes are required. The 10-24 thread size is common in light mechanical assemblies, electrical enclosures, and instrumentation panels. The 4-flute straight flute design performs well in softer materials and shorter chipping applications. It is intended for hand tapping operations using a standard tap wrench or T-handle.

Key Features

• Bottom chamfer style allows threading to within 1-2 threads of the bottom of a blind hole
• 4-flute straight flute geometry provides good chip clearance in short-chipping materials
• High-speed steel (HSS) construction offers durability and resistance to wear during hand tapping
• 10-24 UNC thread standard for compatibility with common unified coarse thread fasteners
• Designed for hand tapping use with standard tap wrenches

Compatibility

Designed for hand tapping 10-24 UNC threaded holes in applications requiring bottom thread chamfer. No specific compatible model or equipment data was provided in the product input.

Installation Notes

This tap is intended for use by machinists, maintenance technicians, and skilled tradespeople performing hand tapping operations. Always secure the workpiece before tapping and use appropriate cutting fluid for the material being threaded. Apply consistent downward pressure while rotating the tap wrench, and back off periodically to break chips and prevent tap binding. Do not force the tap if resistance increases suddenly, as HSS taps are brittle and susceptible to breakage under torsional overload.
