Application guidance
Pilot hole and assembly torque depend on the polymer, fillers, wall thickness and boss geometry. Validate fastening on the actual component; do not automatically apply metric screw tightening torques.
HI-LO and 30° screws have different profiles. PT, DELTA PT and ecosyn plast trade names do not establish automatic equivalence with the geometry shown here.

Specify diameter, required length, quantity, material and finish, together with the component polymer and service conditions.
