18-8/316/ 410 Stainless Steel Philips Pan Head Hi-lo Thread Screw for Plastics
With their reduced minor diameter, these screws displace less plastic material and minimize stress. Each screw has a double lead high and low thread with the high thread having a 30 degree thread form that further minimizes material displacement while providing positive thread engagement.
Reduced Cracking, Splitting and Boss Breakage
The superior performance of the Hi-Lo fastener increases product quality and decreases costs. The 30° included angle of the high thread form reduces radial or bursting pressure to one-half of that generated by the conventional 60° included angle thread form. Boss cracking in plastic is dramatically reduced and smaller diameter bosses can often be specified. In wood applications, even when driving close to the edge, splitting is greatly reduced due to this lower radial pressure.
Increased Pull-Out Strength
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 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.
Lower Driving, Higher Stripping Torques
The 30° 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.
