Indoor TIMBER Structural W.H. Wood Screw 10 in. Black Pkg/50

Code-listed interior structural wood screw designed for wood-to-wood and wood-to-engineered-wood connections. Ideal for mass timber assemblies, cross-laminated timber (CLT), structural insulated panels (SIPs), log home construction, and other interior wood applications.
Its large diameter provides superior holding power and installs faster than traditional lag screws, with no need for additional washers. The integrated large washer head ensures strong clamping between members.
The SawTooth tip enables fast starts, reduces driving torque, and eliminates the need for predrilling in most cases. Serrated threads reduce the risk of wood splitting. The low-profile head maximizes bearing area while allowing smooth countersinking into the wood.
The T40 6-lobe drive provides solid bit engagement and minimizes driver bit wear during installation.
IAPMO ER‑192 code listed, the SDWS TIMBER screw meets IRC® and IBC® building code requirements (2018, 2021, and 2024 editions) for structural interior wood applications.

Drive required : Torx T40 (included)
