The Würth #8 x 1 inch flat head assembly screw is a short-length workhorse for cabinet shop tasks where depth is limited and a flush, clean finish matters. Coarse thread, a Type 17 Auger point, nibs under the flat head, and a combination Phillips/square drive make this screw ready for panel assembly, hardware backing, and light cabinet construction where 1 inch of penetration is exactly what the job calls for.
A 1 inch screw is the right call when material thickness limits how deep you can go. Attaching a thin panel backing to a frame, securing hardware mounting blocks in a shallow cabinet wall, or fastening small cabinet components where anything longer risks punching through — these are the jobs this length was sized for. The flat head seats flush with the surface, and the nibs handle the countersink as the screw drives, so you get a clean result in finished panels without an extra tool change. Shops running high-volume cabinet production keep a box of these on hand for the spots in an assembly where a 1-1/4 inch or longer screw is simply too much.
The zinc plating on this screw provides corrosion protection suited to dry interior environments — cabinet interiors, shop-built furniture, and millwork. This is an indoor screw. For any application involving treated lumber, exterior exposure, or elevated humidity, a corrosion-rated finish is the right choice instead. The carbon steel body and coarse thread profile deliver the pull-out strength expected in solid wood and plywood assembly at this gauge.
The combination drive recess is practical on a busy job: a #2 Phillips bit and a #2 square bit both engage the same recess, so a bit change is rarely needed when switching between tools or crew members. The square recess is designed to hold the screw on a correctly sized bit for easier one-handed placement — useful when positioning small components or working in tight cabinet interiors. Packed 1000 to the box, this screw makes sense for shops that move through volume and want a short assembly screw they can reach for without thinking twice.
When stock thickness is limited — thin panel backs, shallow ledger strips, or small cabinet components — a 1 inch screw gives you a solid bite without risking breakthrough on the back face. It is not a substitute for a longer screw in thicker stock; it is the right tool when depth is genuinely constrained.
The Type 17 Auger point has a fluted tip that cuts and clears wood fiber as the screw enters. It helps the screw start cleanly, lowers the torque needed to drive it, and reduces the chance of splitting when fastening near an edge.
No. The nibs mill a countersink into the wood as the head seats, so in most solid wood and plywood applications you can skip the separate countersink step and still get a flush result.
Yes. The combination recess accepts a #2 Phillips driver or a #2 square driver, so either bit works in the same screw head. Using a correctly sized square bit will give you better torque transfer and bit retention during driving.
No. The zinc finish is rated for dry interior use. Exterior work, treated lumber, or high-humidity environments call for a screw with a corrosion-resistant coating designed for those conditions.
When the job calls for a flush-seating, 1 inch flat head screw with a Type 17 Auger point and a drive that works with the bits already on the bench, this Würth assembly screw delivers a clean, consistent result — box after box.
