HI-LO FASTENERS

HI-Lo® fasteners are the minimal performance solution for fastening in low pressure environments such as plastic, particle board, masonite, and wood. Hi-Lo thread forming screws include a double-lead thread in which the HI thread possesses greater sharpness than a conventional thread. More material is trapped in between the threads which helps to resist pull-out. This also allows for a lower driving torque.

Advantages:

The various advantages of Hi-Lo screws for plastics and metals include:

• 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:

The key features of Hi-Lo screws for metals and plastics include:

• SEMS – add a washer under the head to span larger holes, protect fragile surfaces, and distribute load.
• The high thread 30° included angle 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.
