● The head of the trimming head composite deck screw is a T15 star drive, designed for strong drill bit meshing, it makes your drill absolutely not slippery.
●The screw fastener head has a reverse thread under it so that you will not leave a mushroom head after tightening. The deck screws are ProTech coated for all-weather corrosion protection.
● Screw fasteners boast a very small head and I was able to find the smallest for outdoor use. It leaves small holes and does not split the wood, and if it is a cheap pine molding, it splits, but not in the siding.
