1. An orthopedic implant system, comprising:
a plate including a first surface and a second surface, the plate including at least one aperture, the aperture including one or more female threads which define a thread crest angle T1, and a thread root and at least two recesses within the threads which interrupt the threads to define at least two sections having a thread crest segment and wherein the area of threads comprise areas of thread segments and wherein there is at least one area of thread segments that has no more than two thread segments per area in the direction of the central aperture axis; and
at least one screw including an elongate shaft and a head member having a head configuration including male locking threads, the male locking threads of the head member defining a thread trough angle, T2,
and the male locking threads of the fastener head member and the female threads of the aperture having a differing thread configuration wherein T1 is different to T2 and wherein T2 is from 15° to 45° larger than T1;
wherein the at least one screw is configured for insertion within at least one threaded aperture at a plurality of different insertion angles while achieving a locking engagement between the threaded head and the threaded aperture.
