Boss Design Recommendation
The SHZ Straight Hole Zert is designed to be installed into a straight molded hole with a 1° inclusive taper. The top of the hole should not be countersunk or counterbored as this will decrease the insert’s performance. The recommended hole size applies at the point reached by the bottom of the insert. Molded holes should be used wherever possible as drilled holes may result in diminished performance. Minimum boss wall thicknesses shown are for reference and may vary depending on the type of plastic.
Installation
The insert may be installed by pre-heating or ultrasonic vibration methods. When using heat, the insert should be hot enough to soften the plastic without melting it to avoid flash around the top. Ultrasonic vibration should be applied using low amplitude and the minimum amount of power necessary to satisfactorily soften the plastic. In both methods, avoid excessive pressure that would force an insert into a hole without allowing the plastic to properly soften and flow around the insert features.
