The Würth #8 x 1-1/2" Flat Head Assembly Screw is a production-grade fastener built for cabinet shops and millwork operations that drive screws by the thousands. The 1-1/2" length is a natural fit for fastening into 3/4-inch cabinet panels and face-frame stock, giving the thread enough material to grip without over-penetrating.
At 1-1/2", this screw is at home wherever 3/4-inch panels meet: cabinet box assembly, mounting nailers and cleats to cabinet interiors, securing shelf standards to plywood sides, and fastening wood blocking or backing inside a carcass. The length clears the panel face cleanly and delivers solid thread engagement in the receiving piece without the tip pushing through on thin stock. It also performs well attaching 3/4-inch face-frame components to a cabinet box when driving from behind, a common cabinet shop sequence where length precision matters.
The flat head carries underhead nibs that mill a clean seat as the screw is driven, so the head finishes flush without leaving a raised edge or requiring a separate countersink bit. The Type 17 Auger Point uses an extended cutting flute to remove material at the tip, which lowers driving torque in hard maple, oak, and dense engineered panels and reduces the risk of splitting near edges. Coarse threads run the full engagement length, providing reliable pull-out resistance in the wood-based substrates typical of cabinet interiors. The black finish keeps the fastener low-profile in dark or painted cabinet interiors where a silver head would stand out.
Cabinet shops and millwork teams that run production schedules need fasteners available in quantities that match their output. A box of 7,000 screws covers a sustained run without constant bin-checking. The #2 Phillips drive uses the same bit that most pneumatic and cordless drivers are already loaded with, so there is no tooling change to fit these into an existing workflow. This screw suits shops where consistent performance across thousands of identical joints is the measure that matters, not one-off installations.
When driving from inside the box through 3/4-inch plywood into the back of a face-frame stile, 1-1/2" gives you a solid 3/4" of thread engagement in the face-frame stock. That is a common cabinet shop sequence and this length fits it well.
The Type 17 Auger Point has an extended flute that cuts and evacuates wood fibers as the tip advances. A standard sharp point displaces material without clearing it, which increases driving torque and splitting risk in hardwoods and dense panels. The auger flute reduces both.
No. The underhead nibs mill the countersink seat as the head is driven down. In most wood and laminated panels the head will seat flush in a single operation. Pre-drilling a countersink is not required, though it remains an option in very hard or brittle materials.
Yes. Coarse thread is the correct thread form for particleboard, MDF, and melamine-faced panels. The Type 17 Auger Point helps start the screw cleanly in these materials, and the flat head with nibs seats flush without crumbling the face layer.
No. The black finish on this screw is not rated for exterior or high-moisture exposure. It is an indoor cabinet and woodworking fastener.
When the job calls for a consistent, production-ready screw at a length that covers most 3/4-inch cabinet joinery, the Würth #8 x 1-1/2" Flat Head Assembly Screw delivers the point geometry, thread form, and head design to keep work moving through the shop.
