    Würth #8 x 1-3/8" Washer Head Assembly Screw Combo Drive - Sharp Point Turbo Thread Lubricated, 3670000227961 5000 - 5000/Box

    Description

    #8 x 1-3/8 Washer Head Screw For Wood

    #8 x 1-3/8 washer head screw describes a case hardened, lubricated wood screw designed for woodworking, so it drives firmly into wood while supporting structural joints in cabinets, fixtures, and built-ins. The round washerhead design spreads load over more surface area, which helps keep the head from sinking into soft woods during assembly work. The patented serrated tooth turbo thread starts quickly in wood, allowing the screw to bite fast and move into the workpiece with fewer turns. That same turbo thread reduces splitting in wood, supporting cleaner installations in parts like stiles, rails, and cabinet sides. The screw uses a combo drive that accepts #2 Square Drive bits and #2 Phillips bits, so installers can work with common drivers during assembly and later adjustments. This configuration supports repeatable fastening in cabinet shops and jobsite woodworking.

    Key Washer Head Assembly Screw Details

    • The round washerhead is typically used in soft woods to prevent the head from sinking into the wood, which helps maintain consistent clamping pressure on hinges, slides, and other hardware parts during installation.
    • The patented serrated tooth turbo thread allows for quick starting, so the screw begins cutting into the wood rapidly and supports faster assembly cycles in production or shop settings.
    • The turbo thread reduces splitting in wood, which helps preserve the strength of narrow rails, face frames, and cabinet sides when driving near edges or ends.
    • The thread profile needs less drive torque, which reduces effort on power drivers and can support more consistent seating of heads across repeated installations.
    • The screw is case hardened and lubricated, so the surface treatment and hardness help it drive smoothly into wood while providing a wear-resistant shank for demanding woodworking applications.
    • 3/4 inch and 1 inch lengths are threaded fully while all other sizes are threaded two-thirds from the bottom, which tailors thread engagement to different length ranges for typical woodworking assemblies.
    • The combo drive uses #2 Square Drive bits for insertion and allows #2 Phillips Drive bits for aftermarket adjustment, which lets installers fasten initially with a positive square drive and later tweak alignment using widely available Phillips drivers.
    • The screw is described for use in assembly, face frame, slides, hinges, and hardware across woodworking applications, which makes it suitable for many common cabinet and furniture fastening points.

    Washer Head Screw Drive And Thread Behavior

    The combo drive of this washer head assembly screw uses #2 Square Drive bits for insertion, giving a positive engagement that helps reduce cam-out while pulling joints together. The compatibility with #2 Phillips Drive bits for aftermarket adjustment allows later fine-tuning of hinges, slides, and hardware using standard Phillips tools already on site. The sharp point works with the patented serrated tooth turbo thread to start quickly in wood, so initial penetration is fast and controlled. Because the turbo thread reduces splitting and requires less drive torque, drivers work under lower load, which is useful during repetitive fastening in cabinet production, millwork shops, and installation work where many screws are set in sequence.

    Using Washer Head Assembly Screws In Woodwork

    Where This Washer Head Wood Screw Excels

    Wurth washer head assembly screw is described for all woodworking applications such as assembly, face frame, slides, hinges, and hardware, so it can serve across many points in cabinet and furniture builds. The round washerhead is typically used in soft woods to prevent the head from sinking, which helps keep hardware plates and brackets flush against the surface. In face frame work, that head profile spreads the load on the stile or rail, supporting tight joints without crushing the fibers under the head. When installing slides, the broader bearing area supports the slide flange against the cabinet wall, which helps keep alignment stable as drawers cycle. For hinges and general hardware, the head shape helps maintain consistent contact with the hardware hole, aiding in long-term positioning of doors and moving components.

    Details That Support Consistent Wood Fastening

    The patented serrated tooth turbo thread allows for quick starting, reduced splitting, and less drive torque, which contributes to faster, more predictable screw driving in typical shop materials. Quick starting means the screw engages with fewer revolutions, supporting quicker assembly lines or bench work. Reduced splitting in wood matters when driving near edges or into narrow frames, because it helps preserve the strength of the part as hardware is pulled tight. Less drive torque reduces strain on drills and bits and can support more consistent depth control across large runs of fastenings. Because the screw is case hardened and lubricated, it moves through wood with less friction while maintaining a tough outer surface, helping maintain thread integrity when driving into dense parts of the workpiece. The combo drive that accepts #2 Square Drive bits for insertion and #2 Phillips bits for aftermarket adjustment adds flexibility for installers working across shop and field, supporting straightforward initial fastening and later tuning of hinges and slides.
