The course external thread of SPIROL's Self-Tapping Insert forms an internal thread within a molded or pre-drilled hole during the installation process into a plastic assembly. SPIROL Series 10 Self-Tapping Inserts are thread forming Inserts best suited for softer thermoplastics or thermosets. Self-Tapping Inserts provide the best pull-out resistance for a post-mold installed Insert, yet generally cost more than their post-mold counterparts. The external threads are designed with a thin profile to minimize induced stress in the plastic and have a relative coarse pitch to provide the maximum plastic shear surface to resist pull-out.

To fit leveling feet to round, non-threaded tubes or to fit levelling feet to profiles at right angles Threaded plug/threaded bush: To accommodate adjustable feet on the end face of square tubes or round tubes. Threaded sleeve: To accommodate adjustable feet at right angles to the profile; a hole must be drilled with Ø 17 mm through the profile to allow application Threaded plug/sleeve: Material: : PA plastic, glass-fibre reinforced / threaded insert: nickel-plated brass Colour: black, silver Extras: conductive, other sizes, other colours on request Threaded sleeve: Material: steel Colour: silver Extras: further sizes and surfaces on request

There are many different processes for forming screw threads. The usual method is to machine the thread but threads can also be formed with a thread moulder. The reason is that if the thread is shaped by plastic deformation rather than by cutting, no material is lost. However, thread moulding can only be used on materials with good cold formability.
