The Würth #8 x 1-3/4" flat head assembly screw is a lubricated, turbo-thread fastener built for cabinet boxes, face frames, and casework panels where a clean flush countersink matters. The 1-3/4" length positions it well for joining 3/4" panels with solid backing or bridging two layers of material where a shorter screw would under-penetrate.
At 1-3/4", this screw reaches into the full depth of a 3/4" panel and carries meaningful thread engagement into the substrate beneath it. That makes it a natural fit when fastening a back panel or vertical divider into a cabinet side, securing a solid wood component to an engineered panel, or assembling a drawer box where the combined material thickness calls for more penetration than a 1-1/2" screw provides. The sharp point pulls cleanly through softwood face-frame stock, MDF, and particleboard without splitting the surface layer on typical production materials. For hardwood face-frame rails and stiles, a pilot hole is recommended — the sharp point and turbo thread combination is optimized for softwood, plywood, and sheet goods, not dense hardwoods.
The combo drive recess accepts either a #2 Phillips or a #2 square bit, so a shop running mixed driver setups does not need to stop and sort fasteners. The square recess is designed to hold the screw on a correctly sized bit for one-handed placement, which helps on tight interior cabinet walls where the other hand is holding a panel in position. Turbo thread geometry spaces the threads aggressively for faster advance per revolution, which cuts cycle time across a full box of 1,000 screws. The lubricated finish works alongside the thread design, reducing the friction load on the driver motor and the operator's wrist during sustained runs. Milling nibs under the flat head do double duty: they mill the countersink clean as the head seats and help the head resist spinning back out if the driver disengages before the screw is fully driven.
Production cabinet shops building frameless and face-frame boxes will find the 1,000-count box sized for sustained output rather than occasional use. The lubricated turbo thread and combo drive make this a straightforward choice when the crew runs a mix of drivers or when the job cycles through softwood and engineered-panel materials in the same run. Millwork shops assembling drawer boxes, partitions, and interior fittings get the flush-seat benefit of the nibbed flat head on visible interior surfaces. Contractors assembling and installing pre-built cabinet units on site will appreciate having a screw that seats cleanly without a separate countersink pass when driving through melamine, prefinished plywood, or paint-grade MDF.
Yes. The combo recess accepts a #2 Phillips bit or a #2 square bit. Either drive works in the same head, so you can use whatever bit is already loaded.
The lubrication is applied to the thread and shank surfaces to reduce driving friction. For glued joints, apply glue to the wood faces as you normally would and drive the screw through the center of the joint. Contact between the lubricant and the glue surface is minimal in normal cabinet assembly practice.
The milling nibs under the head are designed to cut a countersink as the screw seats in wood-based panels, including particleboard and MDF substrates. On melamine-faced panels, pre-drilling the countersink is recommended to avoid chipping the laminate surface around the head.
The sharp point and turbo thread are optimized for softwood, MDF, particleboard, plywood, and similar materials. In dense hardwoods such as maple or oak, pre-drill a pilot hole to reduce the risk of splitting and to ensure the head seats cleanly.
When you're fastening through a 3/4" panel into a solid back, divider, or rail, 1-3/4" gives you approximately 1" of thread engagement in the receiving piece. That extra depth over a 1-1/2" screw improves withdrawal resistance in particleboard and MDF cores, which matters in shelving and cabinet boxes that carry sustained loads.
When the job calls for a flat-seat, flush-finish assembly screw that handles softwood and engineered panels without slowing the line, this 1-3/4" lubricated turbo-thread screw covers the range — and a 1,000-count box keeps it covered for the full run.
