![]() The nut plates are dry film lubed for a mandrel only installation using a standard FTI puller unit with a mandrel, nose cap, and chuck assembly optimized for the special characteristics of composites.Īlthough FTI’s installation system for ForceTec in composites uses a much lower expansion level than metals, the resulting torque out values are comparable, as the sample data below indicate. Higher installation reliability and repeatability.įorceTec rivetless nut plates for use in composites are available in stainless steel and titanium in a variety of sizes and configurations including open style, domed, high float, and panel fastener configurations.Improved electrical conductivity through fastened joints to grounding locations.Reduced arcing and laminate damage caused by lightning strike.Hole protection in areas where bare holes can wear or wallow.Faster product installation and joint assembly.Improved open hole compression strength.Each product is radially expanded from an initial clearance fit to lock it into the structure and provide uniform contact with the hole surface resulting in the following advantages over other assembly methods: ![]() They eliminate the risk and time associated with sealants, satellite holes, and other types of interference fit products.

Exceeds MIL-N-25027 requirements for torque and pushout.Reduces production and manufacturing time.In addition, cold expansion of the retainers into the hole imparts compressive residual stresses into the surrounding material, increasing the fatigue performance of the hole. ForceTec installations exceed the requirements of MIL-N-25027 for torque and pushout. The expansion creates high interference between the barrel and the structure that allows the nut plate to resist torque and pushout. Instead, ForceTec is fastened to the structure by radially expanding the ForceTec nut plate barrel into the hole. ForceTec eliminates the need for satellite holes and rivets, which are required for most nut plate installations. ForceTec’s simple installation makes it a cost effective option, significantly reducing labor and maintenance costs over the life of the aircraft. The retainer is designed to be permanent, and only the nut itself requires replacement.įorceTec rivetless nut plate system is widely used as an alternative to traditional riveted nut plates. Unlike conventional riveted or swaged-in nut plates, the ForceTec system radially expands a retainer into a hole. ForceTec is a unique method of installing an innovative and cost effective rivetless nut plate.
