0.315" x 6-1/4" Strong-Drive SDHR Combo-Head Screw - Zinc, Pkg 25 Balusters and residential projectsThe Simpson Strong Tie Strong Drive SDHR Combo Head Screw is made for serious wood projects like cross laminated timber (CLT), mass timber, and other big framing jobs. The unique combo head design gives you flexibility, with a choice to drive it with either a hex bit or a T40 6 lobe bit.
