SPIROL offers Heat/Ultrasonic, Molded-In, Press-In, and Self-Tapping Inserts. Our standard Inserts have been designed for a broad set of plastic applications.
Heat/Ultrasonic Inserts
Series 19 Straight Hole and Series 20 Flanged — Designed for straight holes to yield maximum performance with low radial stress.
Series 29 Standard and Series 30 Flanged — Symmetrical for ease of orientation and enhanced performance designed to maximize torque and pull out values.
Series 14 Tapered Hole — Tapered design for tapered holes for ease of location and reduced installation time.
Self Tapping Inserts
Series 10 Thread Forming — Self-Tapping Inserts are versatile. They can be used in more plastics, including thermoset plastics, while providing the highest, most consistent pullout strength.
Press-In Inserts
Series 50 Symmetrical and Series 51 Headed — Press-In Inserts are designed to be pressed into a plastic hole without melting the plastic prior to installation. They offer rapid installation with no specialized equipment and achieve good overall joint performance.
Molded-In Inserts
Series 63 Through-Hole and Series 65 Blind End — Molded-In Inserts are designed for maximum pull-out and torque performance, and are often the Insert of choice for thermosets and engineered plastics with a high percentage of filler. The minor thread diameter tolerance is controlled to ensure positive positioning and perpendicularity of the Insert on the core pin during the molding process. Series 63 is symmetrical eliminating orientation. Series 65 is the same body style in a blind ended version.
