Würth #8 x 1" Flat Head ASSY Screw RW Drive - Sharp Point Coarse Thread Zinc, 019014025 961 1000 - 1000/Box

Assembly Screw For Thin Panels and Shallow-Stock Joinery

The Würth #8 x 1" ASSY assembly screw is built for cabinet and woodworking applications where stock thickness is limited. At 1 inch, it seats fully in 3/4-inch panels without breakthrough risk, making it the right reach for drawer box sides, cabinet backs, shelf cleats, and other shallow joinery where a longer screw would push through the opposite face.

Key Features

• 1-inch length sizes this screw for 3/4-inch panel stock, keeping the point safely clear of the opposite face.
• Flat head with milling nibs mills its own countersink as the screw seats, leaving a flush, clean finish in wood and engineered panels.
• Sharp point self-starts in softwood, hardwood, and sheet goods without a separate pilot hole in most applications.
• Coarse thread grips wood fiber and engineered panel material for strong withdrawal resistance.
• RW20 drive provides deep, stable bit engagement that transfers torque cleanly and reduces cam-out during repetitive driving.
• Zinc finish suited for interior cabinet and woodworking applications.

Where the 1-Inch Length Earns Its Place

In cabinet construction, the wrong screw length is a production problem. Too long in thin stock and the point breaks through a finished face; too short and thread engagement suffers. At 1 inch, this screw threads fully through a 3/4-inch panel with a controlled bite into the mating surface behind it. That makes it a natural fit for attaching cabinet backs to rabbeted case sides, fastening cleats to interior panels, securing drawer box components, and anywhere else the combined material stack stays under an inch. Production shops pulling from a 1000-count box can standardize this length across similar joints and keep the line moving without measuring each application separately.

Flat Head, Nibs, and the RW20 Drive

The flat head seats flush in wood and panel substrates without a pre-drilled countersink, because the milling nibs on the underside of the head cut their own relief as the screw is driven home. The result is a clean, flat surface at the fastener head with no proud material around the recess. The RW20 drive recess is deeper and broader than standard drive profiles, giving the bit more contact surface and reducing the wobble and slip that wears bits quickly in production use. A correctly sized RW20 bit seats on the screw without play, which also supports one-handed placement when working in tight cabinet interiors.

Who Reaches for This Screw

Cabinet shops assembling frameless and face-frame boxes in volume keep this length on hand specifically for thin-panel joinery. The 1000-count box supports continuous production runs without frequent restocking interruptions. Finish carpenters and installers use it where hardware backing, panel trim, and interior cleats need a short, flush fastener that does not threaten the opposite face. The coarse thread and sharp point work across the materials common to both settings: pine, poplar, maple, birch plywood, melamine-faced particleboard, and MDF. Zinc finish is appropriate for the dry interior environments where these applications live.
