EFC International, headquartered in St Louis, Missouri, USA, is a premier distributor of engineered components, from world class manufacturers, that supplies a variety of industries including automotive, heavy truck, transportation and agriculture, appliance and HVACR, marine RV and small engine, as well as the furniture industry.
In addition to its large range of clamps, panel fasteners, screws, bolts, studs, pins, self-retaining nuts, shaft and retainer bolts, speciality nuts, furniture components, connectors, coupling and fittings, EFC is also able to offer numerous customer support mechanisms to ensure the success of applications and projects.
EFC International points out that within its range of solutions it has a selection of products that are particularly suited for applications in plastics, including the BossScrew™ and GripTide™ insert. EFC says that the BossScrew™ (pictured, left) is the only screw for plastics that is designed not to loosen. Its unique thread form, designed with the patented WERCS® technology, works directly with the creeping aspect of plastic to interlock with the boss. The main advantages of the BossScrew™ are that it reduces the amount of parts needed in assembly; it permits the design of shorter bosses to save material; it increases the clamp load at assembly; and eliminates any buzzing, squeaking or rattling once installed. Applications for the BossScrew™ include under the hood, instrument panels, actuators, drive trains, assemblies, seating and routing.
“The BossScrew™ uses standard head diameters and has installer friendly drive-to-strip ratio. Time, temperature and vibration only strengthen the joint.”
The GripTide™ (pictured, right) is a steel threaded insert for plastics. Due to the strength of the steel used the GripTide™ does not generate any chips or shavings and it requires less thread engagement than brass or aluminium alternatives. Being produced from cold formed steel also helps to reduce material and manufacturing costs.
EFC explains that the GripTide™ exceeds minimum torsion and pull out requirements by creating a permanent mechanical interface in plastics. The GripTide™ is flanged to provide positive stops for installation and available in large bearing surfaces or no flange for mating components.
Applications for the GripTide™ include electronic and engine components, assemblies, seating, instrument panels and routing.
