Big Timber BL148-25 Black Log Structure Screw 25 Ct

Product Description

The BIG TIMBER BL148-25 is a hex-head log structure screw designed for heavy-duty exterior fastening in structural and landscape applications. Sold in a 25-count box, these screws measure 14 x 8 inches and feature a black finish suited for outdoor exposure. The hex-drive head allows high-torque installation with standard impact drivers or hex sockets. ICC certification indicates compliance with recognized building code standards, making these fasteners appropriate for permitted structural work. Carpenters, framers, and general contractors working on log construction, heavy timber framing, or exterior landscaping projects will find these screws a straightforward fastening solution.

These screws are intended for use in decks, structural framing, log home construction, landscape timber connections, and similar exterior applications. The black coating provides a finished appearance while offering corrosion resistance appropriate for outdoor environments. The large diameter and length provide the shear strength and withdrawal resistance needed when joining heavy timber members or anchoring landscape timbers to grade.

Key Features

• ICC certified for code-compliant structural installations
• Hex head drive for high-torque installation with impact drivers or sockets
• Black finish suitable for exterior and exposed applications
• 14 x 8 inch dimensions for heavy timber and log construction fastening
• Sold in a 25-count box for small to mid-scale project quantities

Compatibility

Designed for use in exterior structural applications including deck framing, log home construction, heavy timber framing, and landscape timber connections where a large-diameter structural screw is required.

Installation Notes

Installation should be performed by qualified carpenters or framers following applicable building codes such as the IBC or IRC. Pre-drilling a pilot hole is recommended in dense or dried timber to prevent splitting and reduce drive torque. Use a properly rated impact driver or breaker bar with the correct hex socket to seat the head fully without stripping. Always follow the project engineer or architect specifications for fastener spacing and embedment depth on permitted structural work.
