Product Description

ITW Shakeproof's SINULOC™ MACHINE SCREW is a reusable thread forming specialty machine screw with locking threads. It is designed to provide a lifetime fit in metal applications without the use of additional costly elements such as nylon patches or prevailing torque nuts. These screws have a precision, downward curve added along the helix of the screw thread throughout the body of their screw thread. This unique design provides the exact position, pressure and control necessary to create enough prevailing torque for a lifetime fit within the joint. These screws will withstand vibration, temperature fluctuations, and loss of clamp load, and are reusable with no loss in performance.
