Sharx screws are designed to bite and hold fast in stubborn materials. Sharx are specially engineered with high/low thread form, incorporating indentations, or "teeth." The teeth easily cut through high-density materials and resist back-out even after prolonged vibration.
Sharx Marine Screws are all Phillips Drive, available in Flat Head, Pan Head, and Oval Head. These screws hold fast in fiberglass, plywood, and wood substitute materials, and are ideal for applying trim, rub rail, and molding to fiberglass boat hulls. Made from 316 stainless steel, they are perfect for projects exposed to harsh marine or chemically caustic conditions.
Screws up to 1" in length are fully threaded. Screws more than 1" long are threaded 2/3 of shank length.

Back-out resistance: Once driven home, Sharx are locked in place thanks to their teeth
Holding power: Pull-out values of Sharx screws exceed those of ordinary tapping screws in fiberglass and wood

do you carry 4 x 3/8 pan tapping screws?
Yes, the part number is FSSSTPP4X3/8.
I get that Sharx hold well, but can they be removed if so desired?
I used about 100 or more of these screws #6x1" I believe to fasten 1/4" plywood to 1 1/4" oak frame rafters on a teardrop trailer I'm making. We had to bend it around curves and then epoxy it into place by belt ratcheting strap clamps all within 30 min, the epoxy setup time. We put it in place and drilled our pilot holes and screwed it down dry 1st and then unscrewed all of it before mixing up the epoxy and repeating the whole process, so I can assure you that they not only unscrew but can be reapplied without compromising there holding power.Bill
Yes, they are excellent all the way around. I won't use anything but.
Yes you can But they don't back easy
I HAVE HAD VERY GOOD RESULTS USING THESE SCREWS...THEY ARE EASY TO INSTALL AND REMOVE....I USE THE STAINLESS SCREWS, BECAUSE OF THE SALT AND CORROSIVE ENVIRONMENT ALONG THE LOUISIANA COAST.. HAVE GOOD RESULTS USING THEM AND WOULD RECOMMEND TO ANYONE....
Good product and excellent turn around time
We manufacture a product for agriculture and needed to source specialty stainless steel screws which will hold well in polyethylene cone tanks. These work great and ship very quickly.
The Sharx bite and don't let go.
My application is typically joining wood where I need maximum grab for minimum penetration and no corrosion.
