Thread Forming And Cutting Screws

Features

• Thread-forming screws tightly press their threads into the material for a vibration-resistant assembly.
• Thread-cutting screws are equipped with tapered threads & cutting edges for digging into the material. They generate lesser stress on the material and need lesser driving torque than thread-forming screws.
• Both of these screws are self-tapping for cutting away & removing the surrounding material inside the tapped hole.
• They are divided into 3 parts: the head, the threaded portion and the drill point.
• The head has multiple types of drives for driving the screw in to / out from the surface.
• The threaded portion starts just below the head and is ideal for forming / cutting threads in the workpiece for a secure grip.
• The section below the threads has numerous tapping screw end designs for removing chipped material and improving product performance.
• Selected screws come with a washer to evenly distribute the load and provide a leak-tight seal in outdoor applications.
