HI-LO® Fasteners

The HI-LO® fastener is the minimal performance solution for fastening in low pressure environments such as plastic, particle board, masonite, and wood. It’s designed with a double-lead thread where the HI thread is sharper than a conventional one. More material is trapped in between the threads which helps to resist pull-out. This also allows for a lower driving torque.

Advantages:

  • Perfect screw for low-stress applications
  • Reduced cracking in plastic bosses
  • Smaller sized bosses can be designed to save in material and space
  • Increased pull-out resistance

Available Features:

  • SEMS - add a washer under the head to span larger holes, protect fragile surfaces, and distribute load.
  • The 30º included angle of the high thread displaces less material when it is driven into plastic or wood and, therefore, requires lower driving torques. A greater amount of material remains between the high threads, increasing the stripping torque. Low driving torque and high stripping torque provide maximum protection against stripping problems.
hi lo increased pull out strength axial shear material

The Hi-Lo screw thread configuration has a smaller minor diameter than a conventional screw. The high threads make a deeper cut into the material leaving a greater volume of material between the threads. There is also a greater amount of material in contact with the high, sharp thread and the axial shear area is increased. All of this contributes to greater resistance to pullout and stronger fastening.
