KEY FEATURES AND BENEFITS:
Precise National Fine (NF) Threading: The 7/16"-20 NF thread type creates a finely pitched and strong thread, ideal for applications where a more secure and vibration-resistant fastening is required.
High Carbon Steel (HCS) Construction: Manufactured from high carbon steel, this tap offers a balance of hardness and toughness, providing a sharp, long-lasting cutting edge for reliable performance.
Plug Style Chamfer: The plug tap point, with its 3 to 5 thread chamfer, is the most common and versatile style, allowing for easy starting of new threads and making it suitable for a wide range of general-purpose threading jobs.
Efficient Chip Removal: The four precision-ground straight flutes are designed to efficiently remove chips as you work, preventing clogging and ensuring a smoother, cleaner threading process with less effort.

Prepare the Hole: Using a drill bit with the recommended size of 25/64", create a clean, straight hole in the material you wish to tap. It is crucial that the hole is not oversized, as this will prevent the tap from cutting a full thread.
Align the Tap: Place the tip of the Irwin 7/16"-20 NF HCS Fractional Tap into the prepared hole. Ensure the tap is perfectly aligned at a 90-degree angle to the surface.
Start Threading: Using a tap handle, apply light, even pressure and begin turning the tap clockwise. Turn the tap a half-turn or one full turn.
Clear Chips: After each half-turn to full-turn, reverse the tap a quarter-turn counter-clockwise to break off and clear the chips from the flutes. This prevents the tap from binding or breaking.
Continue Tapping: Repeat the process of turning clockwise and then reversing to clear chips until you have threaded the hole to the desired depth.
