Threaded inserts for plastic

The use of plastic in engineering design continues to grow. To fully take advantage of the wide range of available plastic materials, designers need an equally broad selection of fastening systems.

If your design requires a threaded insert or bolt to be installed in plastic, PSM has a fastener to match your application. We can help you choose the most suitable fastener for your specific requirements.

Sonic-lok®

SL is designed for rapid installation into thermoplastics using heat or ultrasonic. It features opposed helical knurl bands to provide a combination of high torque and pull out resistance.

Spiro®

SP has been designed to cope with the difficulties presented by hard brittle thermoset materials. The sharp precision knurl pattern cuts into these materials reducing radial stresses and allowing thinner boss walls than many other inserts. 37 degree knurl.

Tech-Sonic®

TEC features an unique combination of opposed knurls and knurled vanes providing increased performance levels, Installation is simplified by the symmetrical nature of the insert, eliminating the need for orientation during automated or hand feeding.

Banc-lok®

Ideal for use in hard thermosetting plastic, Banc-loc are press-in expansion inserts which, due to their diamond knurl pattern, give minimum penetration of the sides of the hole without sacrificing pull-out resistance.

Mini-tech®

MTEC is a miniature insert with all the design features and characteristics of the Tech-Sonic range. It is ideal for smaller plastic products and enables the use of very small screws that will provide complete re-usability with no risk of thread stripping problems

Fin-lok®

FL is a press-in insert, which can be easily installed into most thermoplastic materials. It features a combination of sharp fins and straight knurls. Unlike the Press-lok range, this insert has a free running thread.

Heat-lok®

HL is designed for installation into notch sensitive amorphous thermoplastics by heat. It features rounded knurls, avoiding the stress raising sharp crests and roots which typify knurls used on most inserts.

Screw-sert®

SCT range of fasteners have been designed to provide a hardened steel thread in the softer aluminum and zinc based die-castings, magnesium and thermosetting plastics. The external thread cuts into the parent material reducing radial stresses in the casting.

Press-lok®

PLK offers ease of installation without the typical high screw installation torque and its plain and knurled vanes offer the levels of pull-out and torque resistance usually expected only of heat-installed inserts.
