Thread Forming And Cutting Screws

Thread-forming & thread-cutting screws are suitable for creating reusable threads in metals and plastics. They are ideal for metalworking, automobile, maintenance and repair applications. Raptor Supplies offers a wide range of these screws from Grainger. These self-tapping screws need a pre-punched or drilled hole for installation / operation.

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.

Frequently Asked Questions

What is the difference between thread-forming and thread-cutting screws?

  • The differentiating factor is how these screws tap the threads in the material.
  • Thread-cutting screws feature a shank slotted point to progressively cut away the material and form the thread as they are driven down.
  • Thread-forming screws create threads by shaping, moving or displacing the material. They generally have a blunt end and build up the threads more quickly & efficiently.
  • Users should select a thread-cutting screw over a thread-forming screw when dealing with hard materials, threading a big hole or preventing distortion of entry / exit holes.
