The S29, S30 (Long version) are inserts for plastic with heat/ultrasonic installation into cylindrical holes

These are the longer versions of the S29, S30 inserts for higher torque and pull-out resistance

Suitable for all types of thermoplastics, even dry and fragile ones such as polycarbonates

These inserts were designed to provide faster speed and ease of installation, and at the same time maximize torque and pull out performance. The outer profile was made symmetrical with respect to length, so that the insert does not have to be oriented during the installation process. These inserts are therefore suitable for automatic type installations in large volume

The S29, S30 offer much higher torque and pull-out resistance than all other inserts

Holes sizes are identical to those of the S19 and S20 inserts to provide an easy alternative

They induce very low radial stresses and are therefore particularly recommended in holes with thin walls. In this case the hole must be a bit wider. Optimal size should be determined after appropriate practical tests

Installation must be carried out using heat conduction or ultrasonic machines. The holes should be sized as indicated in the product datasheet

They are available in unheaded S29, and headed (flanged) S30 versions. The S30 has the same body style as the S29 with the addition of a head to provide more bearing surface for the mating component to prevent jack-out. In the S29 a screw can be inserted on the opposite side of the flange, allowing to achieve very high pull-out resistance. The head also provides a large contact area, which is useful for electrical contacts and specific applications

Inch version from 2-56 to 5/16-18 is available upon request
