Omg Inc FMHLGM278-50 Headlok Screw 2-7/8 in 50 Pack

Product Description

The OMG INC FMHLGM278-50 is a 2-7/8 inch Headlok structural screw sold in a 50-pack, designed for wood-to-wood fastening applications across residential and light commercial construction. This screw features a non-countersinking head and a patented Spider Drive system that eliminates the need for pre-drilling, reducing installation time on framing and finish carpentry work. The screw is removable after installation, which supports adjustments or disassembly without damaging the substrate. Approved for use with ACQ-treated lumber, it is suited for exterior applications where pressure-treated materials are standard. Carpenters, deck builders, and general contractors are the primary installers.

This fastener is appropriate for a wide range of wood-to-wood connections in both interior and exterior settings. Common applications include deck framing and decking boards, fence construction, header installation, and kitchen cabinet mounting. The no-pre-drill design makes it especially useful on job sites where speed and efficiency matter. ACQ approval makes it a reliable choice wherever pressure-treated lumber is required by code, such as ground-contact framing and exterior structural connections.

Installation Notes

Installation is performed with a compatible Spider Drive bit; confirm the correct bit size before beginning. No pilot hole is required, but fastening into dense hardwoods may benefit from a slow, steady drive speed to prevent screw breakage. When working with ACQ-treated lumber in exterior settings, verify that all hardware and fasteners meet local building code requirements for corrosion resistance. Always wear appropriate PPE when driving fasteners with a power tool.
