This Würth #8 x 1-9/16 inch flat head ASSY assembly screw combines the ASSY thread, an AW20 drive, milling nibs, and a drill point to deliver fast, clean fastening in cabinet construction, casework, and woodworking panels. The 1-9/16 inch length suits common panel thicknesses and close-to-edge applications where a longer screw would over-penetrate.
The 1-9/16 inch length makes this screw well suited for cabinet carcass assembly, drawer box construction, panel-to-panel connections, and casework where material thickness runs between 3/4 inch and 1-1/2 inch combined. The drill point helps the screw start and drive without walking on hard panel surfaces, and the ASSY thread pulls material together with less torque than a standard coarse-thread screw. When fastening close to a panel edge — a frequent requirement in cabinet assembly — the drill point and controlled thread entry help reduce the chance of splitting the substrate. The flat head with milling nibs leaves a flush, clean finish in hardwood faces, laminated panels, and melamine surfaces without requiring a pre-bored countersink in most applications.
The zinc finish provides standard corrosion protection suitable for dry indoor environments including cabinet shops, residential kitchens, baths, and built-in furniture. This screw is designed for interior woodworking and cabinet assembly. For applications with moisture exposure or high humidity, a screw with a more robust corrosion-resistant coating should be specified. The steel construction and ASSY thread geometry support reliable holding power in hardwoods, softwoods, particleboard, MDF, and laminate-faced panels — the materials that make up the majority of cabinet and casework production.
Cabinet shops running production lines will get the most from the 500-piece box and the low-friction ASSY thread, which reduces driver motor strain during high-volume fastening. Finish carpenters and installers assembling cabinets and built-ins on site benefit from the drill point's quick starts and the flat head's flush seating in visible interior panels. The AW20 drive suits anyone who keeps Würth AW bits on hand, and a correctly sized AW20 bit is designed to hold the screw for controlled, one-handed placement in tight cabinet interiors. This is an indoor screw for wood-based assemblies — not for exterior, treated lumber, or wet-area applications.
This screw uses an AW20 drive. Use a correctly sized AW20 bit for best torque transfer and bit retention during installation.
The drill point is designed to help the screw self-start in most wood-based panels without a separate pilot hole. The milling nibs under the flat head help produce a clean countersink as the screw seats, reducing the need for a separate countersink operation in most cabinet materials.
Yes. The ASSY thread reduces driving friction and screw-in force, which helps in denser hardwoods. The drill point also aids starting and chip clearance in harder material.
No. The zinc finish on this screw is rated for dry indoor use. For exterior or treated lumber applications, select a screw with a corrosion-resistant coating rated for those conditions.
The AW drive is a Würth-proprietary drive system engineered specifically for ASSY screws. It is not interchangeable with standard Torx or star drive bits. Using the correct AW20 bit ensures proper fit, torque transfer, and bit life.
Choose this Würth ASSY assembly screw when you need a flat head fastener that starts cleanly, seats flush, and drives efficiently through the hardwoods, softwoods, and engineered panels that make up everyday cabinet and casework production.
