Each self-threading screw type offers distinct advantages and limitations that must be evaluated during design.
Thread-forming screws provide strong, vibration-resistant joints and eliminate chip generation. Their limitations include higher installation torque and narrower material compatibility.
Thread-cutting screws offer versatility and lower torque requirements, making them suitable for a wider range of materials. Their main limitation is slightly reduced joint strength in dynamic conditions.
Understanding these trade-offs helps engineers select fasteners that align with application requirements rather than relying on a single solution.
