Wurth #8 x 2-1/4 inch flat head assembly screw gives installers a sharp point, coarse thread option suited to driving into material without pre-tapping, which speeds assembly when running repeated cabinet or fixture builds on the job or in the shop. The flat head design sits flush in a countersunk hole, helping parts pull tight so hardware, panels, or brackets seat properly against the surface. The screw uses a square drive, aligning with #2 square drive bits for positive engagement that reduces cam-out during power driving and supports consistent depth control. Being case hardened, the screw provides a hardened outer layer that supports driving torque, which matters when working into dense substrates or hitting occasional knots. A lubricated finish on the screw reduces driving friction, which helps fasteners start and seat smoothly and can reduce driver strain over a long run of identical installations.
This Wurth flat head assembly screw is threaded two-thirds from the bottom in this length, so the lower portion pulls into the substrate while the unthreaded upper shank allows outer parts to draw tightly against the base material, which helps close joints. Three-quarter inch and 1 inch lengths in the same line are threaded fully, while all other sizes follow the two-thirds-from-bottom threading pattern, which gives installers a predictable thread engagement profile when choosing lengths within this screw family. The screw uses #2 square drive bits, so a single common bit size handles driving, simplifying bit selection for repeated assemblies. The lubricated finish supports the screw as it advances through the threaded section, which helps it reach full seating torque smoothly and can contribute to a more uniform countersunk finish in aligned rows.
This Wurth #8 x 2-1/4 inch flat head assembly screw sits within Wurth Baer Supply's range of screws and fasteners for the woodworking industry, giving shops a specific length and style suited to structural connections where a flush head is required. The sharp point allows the screw to start directly into the workpiece, so installers can position fasteners along cabinet sides, stretchers, or cleats without cutting threads beforehand. With threading two-thirds from the bottom on this length, the screw engages strongly in the base component while allowing the upper shank to pull the mating piece tight, which can help close small gaps between parts. The coarse thread profile works together with the sharp point so the screw can advance firmly through wood-based materials, supporting strong holding power at the engaged portion of the joint.
The square drive recess is designed for #2 square drive bits, so each bit seats positively into the head for controlled torque transfer, which helps the screw track straight into the pilot or starting point with reduced cam-out. This drive style benefits installers using power drivers over many fasteners, because the bit engagement helps maintain alignment in repetitive fastening patterns. Case hardened construction gives the screw a hardened outer surface, helping it resist wear at the recess and along the shank during driving, which is valuable when screws are run into dense or abrasive substrates common in shop environments. The lubricated finish reduces friction at the threads and shank as the screw advances, so it reaches full seating with smoother torque buildup, which supports repeatable depth and appearance when setting multiple fasteners in visible locations.
This Wurth assembly screw uses a square drive that matches #2 square drive bits, which provides positive engagement with the driver for controlled torque transfer during installation.
The 2-1/4 inch screw is threaded two-thirds from the bottom, so the lower section engages the base material while the upper shank helps pull mating parts tightly together.
The sharp point coarse thread on this screw lets it bite quickly into material, advancing with fewer turns and helping draw components together firmly during assembly.
Case hardened construction gives the screw a hardened outer layer that supports driving torque and helps the head and recess resist wear during powered installation.
This square drive screw is designed for #2 square drive bits, which lets installers rely on a common bit size across assemblies using this screw line.
The lubricated finish lowers friction as the screw advances, helping it seat smoothly at final torque and supporting consistent countersunk head appearance across multiple fasteners.
The Wurth #8 x 2-1/4 inch flat head assembly screw square drive with sharp point coarse thread and lubricated finish offers a combination of length, threading pattern, and drive style suited to many woodworking assemblies. The flat head allows flush seating in countersunk holes, while the square drive and case hardened construction support powered driving with controlled torque. The threading two-thirds from the bottom on this length, along with the sharp point, helps the screw engage firmly in base material and pull joints together. For shops relying on Wurth Baer Supply for screws and fasteners, this screw provides a defined option where a flush head and strong thread engagement are needed in repeated cabinet or fixture builds.
