BAN004 torx cone head 0,6mm

0.6 mm

The second step from the bottom is a compromise between fineness and manageability. Compared with the smallest diameter only a tenth of a millimeter is added, but during the fitting that difference tells: the part holds better in tweezers and the countersink for the cone head is drilled with less risk of the bit sliding off to one side.

Typical places on a scaled-down model

On a motorcycle this size matches the screws that hold the plastic covers, the headlight rims, the data plates or the hose clips. Modelers also reach for it on the dashboard instruments of cars and on the small panels of aircraft, because such joints have a similarly inconspicuous diameter on the real subject.

A procedure that works

• Mark the position of the hole with a needle, and the bit will not slip on a smooth surface.
• Chamfer the edge of the hole, so that the cone part of the head seats without play.
• Apply the glue into the hole, not onto the part, or the excess will flood the recess.
• Once dry, go over the place with fine abrasive paper and dust it again.

How to decide between the steps

Grading in tenths of a millimeter makes it possible to set the joints apart according to their real function, which shows on a finished model more than the choice of a single universal size. If you are not sure, stand two neighboring steps side by side and look at them from an ordinary viewing distance; it usually turns out that the finer option comes across as more faithful than one would expect of it at first glance. Keep the coarser step for places where the real subject carries a real load.
