I've been asked to anchor aluminum threshold
for commercial doors. About six inches wide, and
runs the width of two 36 inch steel doors. One
half of the threshold is loose, and needs maybe
four or so anchors.

Some how, I remember some blue anchors that look
a bit like drywall screws, but have really aggressive
threads. Anyone know what I need for the job?

Where to find these? Lowe's? Need flat head, so as
not to be a trip hazard. Can't have hex heads.

The brand I use are called Tapcons. Pre-drill the
concrete using a masonry bit of the correct size
and lubricate the screws with bees wax.

Aaaahhh , beeswax ! Great idea , thanks . BTW Chris , when you drive these
use a brand new bit in your screw gun . They turn tough and if you cam the
bit outta the socket yer screwed .
Use epoxy instead of beeswax. It lubricates on the way in, and helps
prevent pullout later - - - - -.
