Swageform Is THE High Performance Threadforming Screw

Swageform thread forming screws have been superior performers in automotive, industrial, and consumer assembles for over 25 years, yet they still represent the most efficient, cost-effective concept in thread-forming screw design. Although many improvements have been made in the product's performance, the principle behind its sucesss is as applicaple and as flawless today as it was at its inception, and will remain so as long as thread forming features are a necessity to modern assembly methods. Swageform screws very simply, exhibit performance capabilities and economies far beyond those of thread-forming and thread-cutting tapping screws.

Swageform B fasteners feature the same high performance characteristics associated with Swageform screws in a spaced thread form which is particularly suitable for use in softer materials such as plastic and aluminum. More information...

Eliminate Tapping

Swageform thread forming screws allow you to eliminate the tapping process as the screw will form your threads during installation —if you are tapping holes into metals,consider the savings of eliminating a costly process step.

Switch To The Premium Threadforming Screw

If you are currently using thread-forming screws, such as the common tri-lobular style, consider testing a Swageform. A Swageform will provide you with a higher level of performance in the field as well as an easier, trouble-free assembly process.

 

The Design

Swageform screws incorporate patented lobes on a tapered point. On installation, the initial contact area between the hole and a Swageform screw is limited to only these lobes. In contrast to a standard fully rounded threadforming screw, there is much less surface area contacting the hole during installation with a Swageform. This reduced area of contact results in significantly lower drive torques during the screw installation/threadforming process.

 

Swageform vs. The Competition – A Better Design

Increased contact with the application: Swageform screws have a fully rounded body (versus the common tri-lobular body of many threadforming screws) therefore Swageform’s threads make contact with the application a full 360 degrees – not just three points.

The application material is work hardened during installation

Swageform’s lobes gradually roll back or swage theapplication material while forming the threads – the result is a work hardened, stronger material. There is no cutting of threads that result in a weaker material and metal chips.
