The Würth #8 x 1" flat head assembly screw is a coarse-thread, square-drive fastener built for short-reach applications in cabinet assembly, thin panel work, and hardware backing where a longer screw would penetrate too far. The Type 17 Auger point starts cleanly in wood-based materials, and underhead nibs help the flat head seat flush without a separate countersink step.
At 1 inch, this screw is deliberately short. That is an advantage in several common cabinet and woodworking situations. When attaching a hardware backing strip cut from 3/4-inch plywood, a longer screw risks breaking through the opposite face. In thin drawer-box sides or plywood backs, the same problem appears. The 1-inch length reaches far enough to grip without penetrating through. It is also useful for attaching shelf pin hardware, small mounting brackets, and light fixtures to cabinet interiors where the panel behind the fastening point is visible or finished.
The screw is zinc-plated steel, suited for interior wood assembly in dry conditions. The flat head with nibs seats flush in softwood, plywood, MDF, and particleboard without requiring a pre-drilled countersink in most cases — the nibs mill a clean seat as the head drives home. The #2 square drive transfers torque efficiently and is less prone to cam-out than Phillips under power tools, which matters when driving 1000 screws across a production run. The Type 17 Auger fluted point starts quickly and clears chips, reducing the force needed to seat the screw fully.
Cabinet shops that run high-volume assembly keep short screws on hand alongside their standard lengths because panel work constantly presents thin-stock situations. The 1000-count box suits that kind of production use. Installers finishing cabinet interiors and woodworkers fitting small hardware to finished panels also reach for this length when they need a flat-seating flush fastener that will not blow through. The coarse thread makes it a natural fit for the engineered panel materials — particleboard, MDF, and plywood — that dominate cabinet construction.
In most cabinet panel materials — particleboard, MDF, and plywood — the coarse thread engages enough material to hold firmly in 3/4-inch stock, especially when the joint relies on glue or clamping pressure alongside the fastener. For connections that carry significant load on the screw alone, a longer length provides more thread engagement.
In softwood, plywood, MDF, and particleboard the nibs typically mill a clean seat as the head drives down, so a separate countersink step is usually unnecessary. In harder material, pre-drilling a countersink produces a cleaner result.
The #2 square drive bit is the correct size. Using a correctly sized bit is important for the bit-retention feature to work as designed.
No. The zinc finish is rated for dry interior environments. For exterior work or contact with pressure-treated lumber, a screw with a corrosion-resistant coating rated for those conditions is the right choice.
The coarse thread and Type 17 Auger point work in softwood and engineered panels. In dense hardwood, a fine-thread screw provides better pull-out resistance and is less likely to split the grain. This screw is best suited to softwood and panel materials.
When the job calls for a flush-seating flat head screw that stops short of breaking through thin stock, the Würth #8 x 1" assembly screw is the size to reach for — square drive, Type 17 Auger point, nibs, and a 1000-count box ready for production use.
