Torx Drive Construction Screws - great general purpose construction screw. Full thread flat
head yellow zinc
- T20 torx drive (far better than phillips or pozidriv).
Note - although
Spax classifies these fasteners as "full thread", their
thread dies only go to 2 1/2" on all of their
construction screws. As such, there is noticeable unthreaded
shank under the screw head on sizes 3" and longer. The photo
example shown here is of a 3" long screw.
