    Würth #8 x 1-1/2" Washer Head Assembly Screw Combo Drive - Sharp Point Turbo Thread Lubricated, 3670000223961 1000 - 1000/Box

    Description

    #8 Washer Head Screw For Woodworking Jobs

    #8 x 1-1/2 washer head screw describes a Wurth case hardened, lubricated screw designed for a wide range of woodworking assembly tasks, so installers can use a single fastener across many shop and field operations. The round washer head is typically used in soft woods to prevent the head from sinking into the wood, which helps maintain clamping pressure without crushing the material. This screw uses a combo drive that accepts #2 Square Drive bits to insert, allowing positive engagement during installation. The same screw also works with #2 Phillips Drive bits for after market adjustment, so cabinet doors, slides, or hardware can be fine-tuned without changing tools on site. Lengths longer than 1 inch are threaded 2/3's from the bottom of the screw, which supports strong pull-out where it matters while easing draw-down into face frames and similar assemblies.

    Key Screw Details That Support Woodwork

    • The round washerhead is typically used in soft woods to prevent the head from sinking into wood, which protects the surface during assembly and helps spread load over a wider area on trim, rails, and cabinet parts.
    • The patented serrated tooth turbo thread allows for quick starting, reduced splitting, and less drive torque, so the screw bites fast into stock while limiting material damage and physical effort during repetitive driving.
    • This screw is used in woodworking applications such as assembly, face frame, slides, hinges and hardware, letting shop crews rely on a single fastener style across common cabinet and furniture joints.
    • Case hardened construction with a lubricated finish supports consistent driving into wood, helping the screw cut in smoothly and contributing to repeatable seating depth on production runs.
    • Use with #2 Square Drive bits to insert gives a stable drive interface, while compatibility with #2 Phillips Drive bits for after market adjustment simplifies service work on installed cabinets and fixtures.

    Washer Head Screw Driving And Thread Details

    This Wurth washer head assembly screw uses a combo drive that works with #2 Square Drive bits to insert, which helps maintain bit engagement as the turbo thread pulls the screw into the wood. The same head design accepts #2 Phillips Drive bits for after market adjustment, so hardware or face frames can be brought into alignment later using a widely available driver. The patented serrated tooth turbo thread allows for quick starting, reduced splitting, and less drive torque, which supports faster driving into assembly, face frame, slide, hinge, and hardware locations. On sizes over 1 inch, threading 2/3's from the bottom of the screw focuses the thread where holding power is needed, while the unthreaded upper portion helps draw parts together tightly.

    Using This Wurth Screw In Woodworking Projects

    Where This Washer Head Screw Fits Best

    This Wurth #8 x 1-1/2 inch washer head assembly screw is used in woodworking applications such as assembly, face frame, slides, hinges and hardware, so it fits naturally into cabinet, furniture, and fixture construction. The round washerhead is typically used in soft woods to prevent the head from sinking into wood, which supports use in face frames, cabinet sides, and softwood components without crushing fibers around the head. In slide and hinge locations, the washer head profile spreads bearing pressure over a wider area, which helps support hardware mounting on softer substrates. The turbo thread form is suited to these applications because its quick starting and reduced splitting behavior help keep narrow rails and stiles intact while fastening. Case hardened construction further supports these uses by providing a robust core for repeated driving into dense or layered wood components.

    How Thread, Drive And Length Support Results

    The patented serrated tooth turbo thread allows for quick starting, reduced splitting, and less drive torque, which directly influences installation speed and the quality of the finished joint. Quick starting helps the point locate in assembly fixtures and on layout marks, while reduced splitting supports work near edges on face frames and hardware strips. Less drive torque demands contribute to longer driver life and smoother installation when driving many screws in a run. The combo drive uses #2 Square Drive bits to insert, giving a positive mechanical connection between bit and screw that resists cam-out as the turbo thread engages. Compatibility with #2 Phillips Drive bits for after market adjustment keeps later alignment steps straightforward when tuning hinges or slides. Threading 2/3's from the bottom of the screw on lengths beyond 1 inch places thread engagement deep in the joint while leaving the shank to pull parts together, so installers get clamping and holding power from a single fastener style.
