BAN005 torx convex head Ducati 1,1mm

The second to last step and what comes with it

1.1 mm is the size at which the proportions turn around. While with the smallest diameters what matters is whether the element is visible at all, here it is a question of how it looks from close by. Traces of machining show on the crown, any burr on the foot and leftovers from molding in the recess. It therefore pays to sort the elements before fitting and to keep the handsomest for the places that will be most in view on the finished model.

Which scale calls for this size

In 1:12 scale 1.1 mm would match a real head of over thirteen millimeters, which on a motorcycle is a size reserved for only a very few joints. In 1:9 scale, by contrast, it works out at just under ten millimeters and in 1:6 at six and a half, that is at perfectly ordinary fasteners. This step therefore calls for larger builds, or for a car or a tractor, where the joints are coarser.

Seating in thicker material

The hole will take being drilled with a full millimeter, and in a thicker wall it pays to take it to full depth, so that the shank does not bottom out before the head seats with its face. If you are setting the element into a resin part, clean the hole out first, because resin dust behaves in it like a wedge and the head will stay crooked.

In assemblies where several sizes lie side by side it is practical to start with the larger ones. The smaller steps can then be added to match them and the whole keeps the proportions the real subject shows.

The brand offers the neighboring steps in the same form, so sizes can be changed smoothly without changing the shape of the head.
