3.5mm x 8mm Torx Countersunk Thread Forming Screw for Plastics in BZP

Torx Countersunk thread forming screws for thermo plastics. These thread forming screws have a 30 degree thread angle (flank angle) and an 8 degree thread pitch to optimise performance in all types of thermoplastics and some thermosets. Correctly used these screws will minimise the stress to the plastic and give optimal thread engagement and clamping loads. Please see the data sheet for the recommended pilot pre-drilled or moulded holes required for different plastics. The 6 lobed torx drive is also known as multidrive T or T-drive.
