Phillips Countersunk Head Thread Forming Screw for Plastic

SKU: TFS04 Category:

FasPlas thread forming screw for plastic, with a 30° flank thread angle and countersunk Phillips head, for installation into pre-drilled or moulded holes.

The flank angle results in lower radial expansion than is found in conventional screws and is designed to allow the maximum amount of plastic to be engaged – providing higher shear loads and resistance to pull out due to the increased bearing depth of the thread.

The ease of penetration through the material encourages plastic flow and reduces installation torque, therefore reducing the potential for thread stripping, risk of over-tightening and radial stress on the plastic.

Manufactured in steel or stainless steel, with a range of finishes also available.

Stocked in a number of lengths and diameters from M5 to M25, with non-standard sizes and made to drawing parts available.
