A fastening system according to the present inventioncomprises a screw component (10) and a seating component (20).The screw component comprises a shaft (12) extending along alongitudinal axis (5) and having a maximum radius R1, saidshaft comprising a threaded section (13), said screw componentfurther comprising, at one end of the screw shaft, a head(14), the head comprising a bottom end (15) having a largermaximum radius R2 than the screw shaft such that an exposedunderside (18) of the screw head extends radially beyond themaximum radius of the screw shaft. The seating componentcomprises a screw channel (21) comprising a planar screw seat(22) having a minimum radius R3 which is equal to or greaterthan R1. The bottom end of the screw head comprises an annularcontact surface for abutment against said screw seat, thecontact surface being formed by the distal end of at least onedownwardly extending protrusion (17) on the underside of thescrew head, wherein the annular contact surface has a minimumradius greater than the minimum radius of the screw seat.
