    MAThread®and MATpoint®

    Liscenced to Manufacture by MBM

    MAThread®, MATpoint® and Never-Jam® are patented thread designs, which may be utilized on any externally threaded screw, bolt, or other threaded products. Currently these designs are found on more than 10,000 different fasteners throughout high-volume manufacturing plants worldwide. The licensed design allows for self-correction upon installation.  This ensures confidence that parts will not be damaged or cross-threaded upon installation reducing downtime and costs across the assembly.
