| BI-SERT Rotational Molding Insert - US Threads
The Yardley BI-SERT Insert is designed to provide permanent metal threads in molded plastic parts. Specifically designed for the Rotational Molding process, this versatile insert provides exceptional torque and pull-out resistance. Unique Hex design allows the BI-SERT to be used with fibrous materials where the fibers would normally block the flow of the plastic material around ordinary diamond knurled inserts. Inside diameter held to strict tolerances for a smooth, tight fit on locating pins.
Advantages:
-Hex shape provides exceptional torque and pull-out resistance
-Best design available for use in rotational molding
-Space between the hexes provides excellent flow characteristics, making it ideal for use with fiber-resin plastics
-Inside diameter is reamed for a smooth fit on locating pins
