Press Inserts for Plastic
|240 Series Press Inserts|
|260 Series Press Inserts|
|260 Series Reverse Slot|
Press inserts are threaded inserts designed for post-molding installation in either thermoset plastics or thermoplastics. A slotted design with diamond-knurled OD allows for “cold” installation with optimum torque/pull-out resistance. Cold installation of threaded inserts reduces the cost of moldings and eliminates the need to “chase” threads after molding.
Our press-in inserts are available in three styles: flush, flanged, and reverse slot. All three types press into place for fast, easy installation. Anything from a rubber mallet to an arbor press can be used for installation. E-Z LOK press inserts:
- Install cold
- Reduce the cost of moldings
- Cut reject waste caused by misaligned and faulty inserts
- Eliminate the need to “chase” threads after molding
- Install properly without a precise hole depth
Important Note: Hole size requirements may vary depending on a number of factors, including material and tools. We recommend that you test your particular application before ordering. Contact us for free samples.
Flush vs. Flanged vs. Reverse Slot Press Inserts
Flush press inserts can be installed level with or below the substrate surface. Internal threads from 0-80 to 3/8 and M3 and M6 are available in brass; internal threads from #2 to 3/8 are available in stainless steel.
Flanged press-in inserts provide a large bearing surface, and are ideal for fastening terminal connectors. Internal threads from #2 to 3/8 and M3 to M6 are available in brass; internal threads from #2 to 1/4 are available in stainless steel.
Reverse slot press inserts are designed for installation from the back side of the material and accommodate reverse screw entry for maximum pull-out resistance. Internal threads from #2 to 1/4 are available in brass.
|As the Press Insert is installed, it compresses slightly along the slot. As the fastener is threaded into place, the insert expands and the diamond knurl is pressed into the wall of the hole, securing the insert in place.|
Thermoset Plastics vs. Thermoplastics
Due to an irreversible chemical reaction that occurs during the thermosetting process, thermoset plastics can be melted and shaped only once. Typical examples of thermoset plastics include fiberglass, polyurethane, melamine, polyester, and urea.
Thermoplastics do not undergo a chemical change when molded. They can be molded and remolded over and over. Typical examples of thermoplastics include polyvinyl chloride (PVC), nylon, polypropylene, acrylic, and polyethylene.
E-Z LOK’s press-in inserts feature a slotted design with diamond-knurled OD that allows “cold” installation and provides optimum torque/pull-out resistance. Cold installation of threaded inserts reduces the cost of moldings and eliminates the need to “chase” threads after molding.
