Please note that large size Round Head wood screws will have smaller heads - the shank size is the same. If the head size is critical, please contact us.
The largest wood screw that Nettlefolds produced was a size 32. The smallest was a size 0000 The shank of the screw at the widest point was exactly half the width of the head.
A size 32 screw was given a head diameter of one inch and a shank diameter of half inch. A size 0000 has a head diameter of 108/1000 of an inch and a shank diameter of 54/1000 of an inch. The diameters of the heads reduced by 28/1000 of an inch, and the shanks reduced by 14/1000 of an inch for each size of screw until they got down to a size 1. They then reduced the diameters by just 6/1000 and 3/1000 respectively.
