Abstract
A flat-head pin includes: (a) a pin shaft with a pin point; (b) a flat pin head affixed to an end of the pin shaft distal to the pin point; wherein the flat pin head is characterized by a cuboid shape, preferably a tapered cuboid shape with a plurality of transverse gripping ribs spaced a distance, s, from each other. The flat pin head is characterized by a tapered cuboid shape with a plurality of transverse gripping ribs spaced a distance, s, preferably wherein the distance s is relatively large and there are relatively few gripping ribs, such as 3-5 transverse gripping ribs.

A flat-head pin comprising:
- (a) a pin shaft with a pin point;
- and
- (b) a flat pin head affixed to an end of the pin shaft distal to the pin point;
- wherein the flat pin head is characterized by a tapered cuboid shape with a plurality of transverse gripping ribs spaced a distance, s, from each other and a plurality of semicylindrical segments having a common diameter interposed between the transverse gripping ribs, wherein the semicylindrical segments are coaxial with a longitudinal axis of the pin shaft;
- wherein the flat pin head tapers from an inner characteristic width, iw, adjacent the pin shaft to a longer outer characteristic width, ow, such that the taper occurs over a length L of the flat pin head;
- and
- wherein the distance, s, is from 0.7 mm to 1.25 mm.
