PWR Drive is the new premium line of screw products from Reliable. The PWR Drive FIT trim head screw is used for all trim applications and specializes in assembling stronger miters. This screw has a special drill tip to help with tricky angle starts, outperforming type 17 to prevent wood splitting. This feature allows the FIT to be used for face screwing but also on the side of regular 3/4 in wood boards. The biggest asset of the FIT is its ”slow” second thread producing a clamping effect giving an unmatched assembly strength. In essence, since all trim head screws have by nature small heads that cannot push, the second thread replaces the strength that the head of a regular flat head wood screw would produce. The FIT is the best of both worlds: Assembly strength with a small head that almost disappears. All FIT screws come with a certified corrosion resistant coating compliant with the IBC and IRC building codes. Watch the video to see the benefit it brings to deck staircase assemblies
