    Würth #8 x 2-1/2" Washer Head Installation Screw Phillips/Square Drive - Sharp Point Coarse Thread Black, 3670000196961 2000 - 2000/Box

    Description

    #8 Washer Head Installation Screw For Wood

    #8 x 2-1/2 washer head installation screw describes a case hardened fastener sized for jobs that need extra bite and head bearing area, giving cabinet and woodworking installations a solid hold in typical substrates. The washer style round head spreads the load across a broader surface, which helps reduce head pull-through when you are fastening components against wood or similar materials. This Wurth screw uses a sharp point with coarse thread, so it cuts in quickly and advances with fewer turns, keeping driving effort low on repetitive installation work. The black and zinc finish identifies the screw easily against most materials while providing a clean, finished look in visible locations. With its combination Phillips and square drive design, the same screw can be driven during installation and then adjusted later using different bit styles, supporting both initial fit-up and after market adjustment work.

    Fastener Details That Support Daily Jobs

    • The case hardened construction gives the screw a hard outer surface for driving while maintaining strength in typical cabinet and woodworking uses, which helps it stand up to repeated driving and removal during fitting work.
    • The sharp point with coarse thread lets the screw start into material quickly and bite aggressively, which helps it pull components together firmly with less driving time on each fastener.
    • The round washer head offers a broader bearing surface than a standard head, which helps distribute clamping force and can reduce crushing in the material directly under the head.
    • The black and zinc finish provides a dark appearance on the head while still being described as zinc, which supports both visual contrast and a finished look on exposed fastener locations.
    • The screw is sold in full box quantities only, which supports stocking for recurring installation work where consistent product is needed across multiple jobs.

    Drive Style And Installation Workflow

    This Wurth installation screw uses a #2 square drive bit for initial insertion, which provides a positive bit engagement for driving the screw into place on the job. The same fastener also accepts a #2 Phillips drive bit for after market adjustment, so installers can come back with commonly carried Phillips bits to tweak alignment without changing hardware. This dual-drive approach means the screw supports both controlled driving during primary installation and straightforward adjustment work later, keeping fastener interaction simple across different stages of a project. With its coarse thread and sharp point, the screw advances efficiently once the bit is engaged, fitting into a typical cabinet or woodworking workflow where multiple fasteners are set in sequence.

    Using This Wurth Screw In Real Projects

    Where A Washer Head Installation Screw Fits

    This Wurth #8 x 2-1/2 inch washer head installation screw fits tasks that benefit from a broad head bearing on the surface, such as fastening components where pull-through resistance matters. The round washer head sits against the material and spreads the load more than a smaller head profile, which is useful when parts are drawn tight against wood or composite panels. A sharp point combined with coarse thread suits applications where the screw needs to bite in quickly and pull parts together decisively, supporting typical installation steps in cabinet or woodworking environments. The black and zinc description identifies the screw visually when sorting fasteners, helping crews match the same product across different areas of a project. Because the screw is sold in full box quantities only, it supports jobs that repeat the same fastening pattern and benefit from using consistent screws from start to finish.

    Details That Help Repeatable Installation Results

    The case hardened construction of this installation screw provides a hard driving surface at the outer layer, which supports repeated interactions with #2 square drive bits during initial fastening. That hardened surface also matters when a #2 Phillips drive bit is used for after market adjustment, helping the drive recess hold its shape through multiple adjustments. The combination of square drive for insertion and Phillips drive for later adjustment gives installers flexibility with common bit types across the life of the installation. The coarse thread pairs with the screw length of 2-1/2 inches to advance firmly through material, which supports consistent pull-down of parts when the same driving technique is used across many screws. In practice, these details work together so that the screw behaves predictably from the first drive through any later adjustment, reducing variability in how components draw together on repeated installations.
