Lo-Driv® Thread Rolling Screw
The unique point and body design provide superior forming pressure relief which lowers driving torque. The thread forming screws forming relief feature extends all the way up into the body where the circumference of the threads are at their largest diameter. Lower driving torque allows drivers to drive screws faster and reduces operator fatigue.
As soon as the relief area of the Lo-Driv thread passes through the assembly, the driving torque drops almost to zero. All of the driver's energy is then converted into high clamping force, which keeps assemblies tight during use. This helps to reduce repair and warranty costs associated with loosening screws. When Lo-Driv Screws are driven into drilled or cast holes of the correct size they create strong, tightly mating internal threads. The screws can not cross thread when driven because they create their own mating threads in the assembly. The 360° body contact of Lo-Driv Screws is highly resistant to stripping out when being seated. Lo-Driv Screws meet all of the requirements of the following specifications: IFI-112, SAE J81, GM6171M and Ford ES21003-S100. See Engineering Data for hole size specifications. |

Lo-Driv®
Thread Rolling Screws can lower the cost of assembly operations several
ways. They improve the speed of assembly, reduce operator fatigue
and strip-out problems, eliminate the need to pre-tap holes and cross
threading.
