#6 Flat head slotted bronze wood screws. Traditional boatbuilders love these Silicon Bronze wood screws because they have cut threads and the full-bodied diameter shank. Unlike rolled thread screws with their reduced shank, these screws have a shank diameter that is the same size as the outside of the threads. This completely fills the clearance hole normally drilled for the shank thus creating a waterproof seal. Remember to drill a body hole for the screw shank and a pilot hole for the threads. All screws are threaded for 2/3 of the shank.

She was a great screw. Her dimensions were perfect. But seriously folks, I was asked to review these silicon bronze #6-1½" screws. Using a caliper, I found the dimensions to be spot on to the requirements. Since these may see a drop of salt water, the material criteria (SiBr) was important to me. Using an H.D.Smith Perfect Handle screwdriver, each was applied to a predrilled hole. I used a long out of production Stanley Adjustable Screwmate, as the root diameter of the screw matches the pilot hole; yielding the highest extraction force. The shank component of the Screwmate is undersized, yielding a modest compression fit. A few wraps of cotton wicking and, viola, the installation is done.

A necessary item for a classic boat restoration. Pricing was fair and delivery was - as usual - quick!
