3.5mm diameter Pozi Countersunk Thread Forming Screws for Plastics, 30 Degree Thread in Bright Zinc Plated (BZP) Steel

Pozi 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.
