AEL SPINTITE RIVETNUT M6X1 [4.19-6.60mmGR] LG FLNG HDCan be used in a wide range of applications and are designed to provide a very efficient and cost-effective method of placing permanent threads in thin materials. Installed from one side, Rivet-Nuts/Ribbed are perfect for use in metals, fiberglass and rigid plastic previously to thin for tapped threads. Rivets/Ribbed provide a neat appearance and once in place, the internal threads are ready for a screw or bolt. Additional features of the ribbed rivet-nut include: Increased torque strength over conventional style, 360 Degrees knurled expansion after setting, vibration resistance and large flanged head which increases push out strength. Available in steel only with yellow zinc dichromate finish and in a wide range of sizes: 6-32 thru 1/4-20, 5/16 and 3/8-16, M4 thru M10;. Standard and extended grip ranges are available in each size. Lightweight tooling assures easy installation by the operator and reduces costs when compared with other methods. After installation, Klik Rivet-Nuts/Ribbed provide permanent, captive threads that do not allow loosening under vibration and will not rotate when attached to the mating material. Rivet-Nuts/Ribbed with large diameter heads can be used in soft materials which inherently offer little, if any thread strength. The flathead design provide the most bearing surface for higher torque applications. The larger flange extends above the material in which it is installed and provides a built-in spacer.
