The Würth #8 x 1-5/8" flat head assembly screw is built for cabinet and furniture production where 3/4-inch stock is the standard thickness. A coarse thread, Type 17 Auger point, nibs under the flat head, and a #2 Phillips drive combine to make this a dependable daily-use fastener for interior wood assembly. The box contains 5,500 screws to keep production runs moving without frequent reorders.
Most cabinet boxes and face-frame components are built from 3/4-inch material. A 1-5/8" screw driven through one panel and into the edge or face of another leaves roughly 7/8 inch of thread engagement in the receiving piece, which is enough to hold the joint securely under the racking and shear loads that assembled cabinets see in everyday use. This length also works for drawer box assembly, back panel attachment on thinner boxes, and general furniture joinery where similar stack thicknesses appear. It avoids the over-penetration risk that longer screws carry in thinner panels, making it a lower-risk choice for production work where operators are driving hundreds of screws in a shift.
The Type 17 Auger point has a flute cut into the tip that removes wood fibers as the screw enters the material rather than compressing them. In dense hardwood and in thick plywood, this translates to less resistance at the start of the drive and a lower chance of splitting near the tip. The flat head carries small nibs on its bearing surface that act as milling cutters: as the head pulls flush, the nibs relieve the wood fibers directly under the head and seat the screw cleanly without requiring a pre-drilled countersink in most wood-based substrates. For cabinet shops running volume work, those two design details reduce the setup steps per joint and the likelihood of a visible surface defect around the fastener.
The black finish and #8 gauge are a common pairing in cabinet interior work, where the fastener color matters less than head seating and driving consistency. The #2 Phillips drive means any standard driver bit in the shop or on the truck will work without a changeover. The 5,500-count box is scaled for shops or crews that go through assembly screws in volume, cutting down the per-screw cost and the frequency of replenishment orders. This screw is for interior, dry-environment work; it is not intended for exterior exposure or treated-lumber applications.
When driving through one 3/4-inch panel into the edge or face of a second panel, 1-5/8" leaves close to 7/8 inch of thread in the receiving piece. That engagement depth gives a solid mechanical connection without the screw breaking through the far face of thinner stock.
Not in most wood-based panels. The nibs mill the countersink as the head seats, so the screw can go flush in plywood, MDF, particleboard, and most solid woods without a separate countersink step. Very hard or brittle materials may still benefit from pre-drilling.
The Type 17 Auger point has a longitudinal flute that cuts and removes wood fibers at the tip rather than displacing them. This lowers driving resistance and reduces the splitting risk that a plain sharp point can cause in hardwood or dense plywood near an edge.
The coarse thread on this screw is sized for softwood, plywood, MDF, and particleboard. For hardwood face frames, a fine-thread face-frame screw is the better choice because fine threads grip tight-grained hardwood more effectively and reduce splitting risk in narrow stile stock.
No. This screw carries a black finish suited to indoor, dry conditions. Exterior work and pressure-treated lumber require a corrosion-resistant coating rated for outdoor exposure.
The Würth #8 x 1-5/8" assembly screw is a straightforward, well-matched fastener for the panel thicknesses and production pace of a cabinet or furniture shop, with the point, head, and pack quantity to keep assembly moving without interruption.
