Flat head assembly screw combo drive describes this Wurth #8 x 3 inch fastener, which is designed to draw parts together while sitting flush in a countersunk hole so work surfaces stay even during cabinet or fixture assembly. The screw uses a sharp point with coarse thread, so it bites quickly into material and advances with fewer turns, supporting faster driving in typical woodworking or shop-fastening tasks. The coarse thread is lubricated, which reduces driving friction and helps the screw seat fully with less effort, useful when running many screws on repetitive jobs. This screw is case hardened, so the outer layer is engineered to better resist wear at the head and threads during driving, which matters when you are using powered drivers or removing and reinstalling in the same hole. The product is listed under Wurth Baer Supply fasteners in the screws product class.
This assembly screw uses #2 square drive bits to insert, so installers can rely on a positive bit engagement that helps reduce cam-out when driving into denser materials or at shallow angles. The same screw can also be turned with #2 Phillips drive bits for after market adjustment, so service work or fine tuning on site can be handled with a commonly carried bit style even if the original square bit is not at hand. Because both drive types work on the same combo drive recess, re-seating or backing out the screw for alignment changes is straightforward, which supports small adjustments during cabinet, fixture, or component alignment without switching hardware.
The Wurth #8 x 3 inch screw sits within the Wurth Baer Supply screws category, so it lines up with typical woodworking and cabinet-related fastening needs where consistent pull-down is required. Its length gives extra reach through thicker build-ups or through-face fastening situations while the #8 diameter remains suited to many wood-based substrates, so installers can span parts such as applied strips or build-up layers. The flat head geometry seats into countersinks in wood or similar materials, so the screw can hold firmly while leaving a surface ready for later finishing steps. Because the thread is coarse and lubricated, the screw advances readily through stock, which supports production runs in a woodworking environment where repeated cycles matter.
The case hardened design supports the combo drive recess under repeated driver engagement, which is practical when fastening long runs where each screw may see brief stalls or angle changes from the driver. Using #2 square drive bits during primary installation provides a positive mechanical engagement, so torque transfer remains consistent as screws are seated deep into a joint. When after market adjustment is needed, the compatibility with #2 Phillips drive bits lets the same fastener be backed off or snugged up using a widely available driver style, which keeps on-site alignment work straightforward. The lubricated coarse thread also assists during these adjustments, as lower friction in the thread helps the screw move in or out with less resistance, which reduces the effort needed when realigning components or fine-tuning fit. By combining case hardening, a flat head, coarse lubricated thread, and combo drive, this part number 3670000413961 1500 offers a screw layout that supports both first-time installation and later adjustment work in assembled pieces.
The Wurth #8 x 3 inch screw uses #2 square drive bits for installation, so drivers can transmit torque securely, and it also accepts #2 Phillips drive bits for after market adjustment work.
The lubricated coarse thread on this assembly screw reduces friction as it advances, which helps the screw pull parts together more efficiently and eases driving in repetitive fastening tasks.
The case hardened structure gives the outer surface of the screw added wear resistance at the head and threads, which supports repeated driver engagement and removal without deforming the recess.
The flat head on this assembly screw seats into a countersunk hole so the top of the head sits level with the surface, which helps assembled parts present a flush, unobtrusive face.
The sharp point lets the screw penetrate material directly, so it can start and advance into many substrates without a pilot in suitable situations, saving a drilling step in some workflows.
Part number 3670000413961 1500 identifies this specific Wurth #8 x 3 inch flat head, sharp point, coarse thread, lubricated assembly screw in the Wurth Baer Supply screws lineup.
The Wurth #8 x 3 inch flat head assembly screw combo drive sharp point coarse thread lubricated design supports projects where a flush head, efficient driving, and later adjustment with #2 Phillips bits are valuable. By using #2 square drive bits for primary installation, this screw helps deliver consistent seating in wood-focused assemblies while the lubricated coarse thread works to pull parts tight. For cabinet, woodworking, or general shop builds that match its size and style, this part 3670000413961 1500 offers a practical fastening choice within the Wurth Baer Supply screws category.
