Most folks don’t realize how important fasteners are today with finish hardware. Most screws are Phillips head or not the finish or quality you require for your project.
We provide screws from head size 1 all the way to 14 in oval, flat, and round heads. We offer various lengths and fit screws to the appropriate countersinks. Amazingly enough most manufacturers have stopped producing odd size screws (ie 5,7,9,11). Interestingly enough all of the hardware manufactured in years gone by was done so with the odd sizes. This is why so many polishing shops cannot ‘fit’ the appropriate fastener with your parts.
It pays to spend a little time up front discussing what you are going into (ie a window frame, or jamb, etc) and pre-fit screws. Above all ask for a few extra (we do this automatically for you) because even the most carefull person can damage a screw head.
