These screws let you level and plumb without the need for shims when installing door jambs, window frames, cabinets and panels.
An 11/16" collar section surrounds the head and rotates freely on the main shank. A two-piece crown bit (sold separately) engages the collar and the screw simultaneously, turning both until the collar seats flush. By removing the outer crown portion of the bit, you can then turn the main Torx-drive screw shank alone, to adjust for plumb or level. Steel with zinc plating for corrosion resistance.Â
Suitable for fastening wood to wood or wood to masonry (not intended for vinyl). Sold in packages of six.
