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.
