The Würth #8 x 1" flat head assembly screw is built for cabinet and woodworking joints where material thickness is limited and driving close to a panel edge or face requires a controlled, shorter fastener. Coarse thread, a Type 17 auger point, flat head with nibs, and a combination Phillips/square drive give this screw a precise match to the demands of shallow stock and tight quarters.
A 1-inch screw is the right call when the stock simply will not accommodate more. Joining 1/2-inch cabinet backs to a light frame, fastening hardware backing strips, securing thin divider panels, or assembling components in narrow stiles — these are the jobs where a standard 1-1/4-inch or longer screw would push through the far face or land too close to a finished surface. At 1 inch, this screw delivers a full threaded bite without the over-penetration risk. The Type 17 auger point clears material at the tip cleanly, which matters most in shorter screws where there is less thread travel before the head seats. The flat head with nibs mills its own countersink as it seats, so the head finishes flush without pre-boring a separate countersink hole — useful when the work is moving quickly through a production run or a tight install.
The black finish on this screw blends with painted, dark-laminate, or black-coated cabinet interiors, which makes the seated head far less visible than a zinc-plated screw would be in those surfaces. Coarse thread is the correct choice here: in the softwoods, plywood, MDF, particleboard, and melamine-faced panels that make up the bulk of cabinet carcass and face-frame work, coarse thread holds more reliably than fine thread in the same material. The flat head profile keeps the screw flush or just below the surface when the nibs have done their work, and flush seating matters whenever a laminate edge, panel face, or glued joint will sit on top.
This screw suits cabinet shops running softwood or sheet-goods carcasses, installers fastening thin sub-components during cabinet assembly, and woodworkers who keep a short flat head on hand for light joinery in panels under 3/4 inch. The combination drive accepts a #2 Phillips or a #2 square bit — the square recess is designed to hold the screw on a correctly sized bit for one-handed placement, which simplifies working in confined cabinet interiors. Packed 1000 to the box, the quantity supports production use without frequent restocking.
When the receiving material is thin — a 1/2-inch back panel, a narrow stile, or a light frame member — a longer screw risks breaking through the far face. The 1-inch length keeps the tip well clear of the opposite surface while still delivering full thread engagement in the panel.
The Type 17 auger point has a longitudinal flute that removes wood fibers as the screw starts, reducing the radial pressure that causes splitting. On a short screw like this one, that chip clearance at the tip makes starting cleaner and lowers splitting risk near panel edges.
Yes. The combination recess accepts both a #2 Phillips and a #2 square driver in the same opening, so either bit works for installation.
No. The nibs mill their own countersink in wood-based materials as the screw seats, so in most cabinet substrates — softwood, MDF, plywood, particleboard — the head seats flush without a separate countersink step.
Coarse thread is the right choice for MDF, particleboard, plywood, and softwood. The wider thread spacing grips more material volume in low-density engineered panels and provides better pull-out resistance than fine thread in those substrates.
When thin stock, shallow joints, or tight panel clearances are the constraint, the Würth #8 x 1" assembly screw gives you a clean-starting, flush-seating flat head screw that fits the job without over-penetrating the material.
