National Marker N224386 Phillips Flat Head Wood Screw 18ct

Product Description

The NATIONAL MARKER N224386 is a No. 12 x 1.25-inch Phillips flat head wood screw designed to fasten heavy-duty strap hinges, T-hinges, and gate hinges in demanding applications. Manufactured from steel with a black finish, these screws provide the holding strength and corrosion resistance needed for gate and door hardware in both residential and light commercial settings. Each pack contains 18 screws, giving the installer enough fasteners to complete a full hinge installation without a separate hardware run. Licensed tradespeople and experienced DIYers working on gate or door assemblies will find these screws sized and threaded specifically for the hardware they accompany.

These screws are specified for use with National 6-inch and 8-inch model No. 282 strap hinges, 6-inch and 8-inch model No. 286 T-hinges, and model No. 287 gate hinges. The flat head profile sits flush with the surface after driving, which keeps gate hardware low-profile and reduces snagging. The Phillips drive pattern is compatible with standard power drivers and hand screwdrivers, making installation straightforward in the field.

Installation Notes

Installation is typically performed by carpenters, general contractors, or experienced DIYers as part of gate or door hardware assembly. Pre-drilling a pilot hole in hardwood substrates helps prevent wood splitting and ensures the screw drives straight. Drive screws to flush or just below the surface without over-torquing, which can strip the wood or shear the fastener. Follow any local building code requirements for gate and fence hardware in structural applications.
