It’s always great to find a way to reduce costs and speed up production without compromising quality.
What if you could save your valuable time and money by eliminating the need to pre-tap for standard screws, or stop fretting over difficult material that won’t easily allow thread-forming?
This might be a great opportunity for you to consider using thread-cutting screws.
These fasteners cut a reliable mating thread with little more than a simple pilot hole – and since they don’t deform their own threads they remain reliable during service.
Below you’ll find our guide to the various types of thread-cutting screws and their applications. Aspen’s Experts can tell you if you can benefit from their unique features – and of course we’re always ready to answer your questions.
Thread Cutting Screws
· A type of screw that has a cutting point and edges that produces a mating thread by removing material from the engaged section
· Creates a perfectly formed mating thread, allowing a stronger joint
· No need for a separate tapping operation
· Thread-cutting screws come in a variety of head styles, drive types, materials and platings.
· The threading and point differentiate the types, with types 1, F, 23 and 25 being the most common.
· Please note that for this reason, only the screw shaft is illustrated.

A Machine Screw thread with a blunt point and single cutting edge for general use. Produces a fine standard machine screw thread for field replacement. May be used in sheet metals, structural shapes, alloys and plastics
A Machine Screw thread with a blunt point, and multiple cutting edges. May be used in heavy gauge sheet metal, aluminum, zinc and lead die castings, cast iron, brass and plastic.
A Machine Screw thread with a blunt point, tapered entering threads and a single wide cutting edge with a chip cavity. May be used in cast iron, zinc and aluminum die castings and plasics. Provides maximum thread cutting area and excellent chip clearing, with minimum tightening torques.
A Coarse Type B thread with a blunt point, tapered entering threads and a single wide cutting edge with chip cavity. For plastics and other soft materials with large chip clearing and cutting edges.
