Polyplast 30 Hex Washer Head

The 30 deg. Flank angle produces low radial forces when engaging the plastic, therefore resulting in less radial stresses, in other words the hoop stresses in the plastic bosses are less than those experienced with conventional screws. The recessed core geometry provides the ideal flow director for the displaced plastic, encouraging a uniform flow to fill the pitch of the screw without material jamming. This results in the maximum amount of plastic being engaged providing higher sheer loads and pull out force.
