#8 x 1-1/2 flat head assembly screw gives you a standard size fastener for common woodworking assembly tasks, so you can tie components together with a familiar length that coordinates easily with material thicknesses on repeat jobs. The flat head design allows the screw to seat flush in a countersunk hole, which helps parts pull tight without a proud head interfering with face frames, panels, or hardware placement. This screw is an assembly screw in the Wurth fasteners and screws category, so it is built for fastening components rather than temporary jigging, supporting consistent performance across similar builds. The sharp point lets the screw bite quickly into the substrate, which speeds driving and reduces wandering when you are aligning parts by hand or with basic shop fixtures. Coarse thread gearing is suited to softer materials because it advances quickly, which helps clamp joint faces together in fewer turns. The lubricated description indicates a treated surface that lowers driving friction, so screws advance more smoothly and reduce driver strain in manual or powered installation workflows.
The web description notes that 3/4 inch and 1 inch lengths in this line are threaded fully, while all other sizes are threaded two-thirds from the bottom of the screw, which means this 1-1/2 inch size follows the two-thirds threading pattern to allow a portion of shank near the head. That partial shank above the coarse threads lets the screw pull the top piece down onto the lower piece, which is useful in assembly work where clamping force between layers matters more than full-length thread engagement in the upper material. This threading layout helps the lower part of the screw lock into the receiving material while the smooth section can slide through the top piece, so parts are drawn tight without jacking them apart, which supports tighter joints on face frames and carcass work.
This Wurth flat head assembly screw uses #2 square drive bits, so installers can work with a common bit size that delivers positive engagement between driver and recess during fastening. That square drive interface helps transfer torque more directly into the screw head, which matters on lubricated coarse threads that advance quickly and can see higher driving loads as they clamp parts together. The screw is described as case hardened, so the outer surface is treated for hardness while the core remains tougher, which supports a balance between resistance to head wear and the ability to handle driving forces during assembly. Case hardening helps the recess and bearing surfaces better resist deformation under torque, which maintains driver fit over repeated installation cycles on projects that require many screws. The manufacturer description notes that finishes are listed separately, indicating that this screw belongs to a broader system of finishes under the same line, so you can align finish choice with other fasteners in the same installation family.
The note that all sizes in this line other than 3/4 inch and 1 inch are threaded two-thirds from the bottom of the screw shows that the 1-1/2 inch length shares a consistent threading pattern with its longer companions, which simplifies planning when you change lengths on related assemblies. That consistent partial-thread configuration lets you expect similar clamping behavior across different thickness stacks, so you can keep joint design stable while only adjusting length as project dimensions vary. The product is sold in full box quantities only, which is geared toward professional or high-volume users who standardize on a particular screw for recurring jobs. Bulk packs are available as shown for this part number, so shops can load drivers, collate work, and keep fastener changes during the day to a minimum. The description that packing uses standard boxes of 1,000 and bulk packs ties this screw into a scalable supply approach, so as projects grow you can step up to larger counts without changing the fastener specification that your jigs and procedures already follow.
The lubricated coarse thread assembly screw is designed as an assembly screw with coarse threading, which works well where faster advancement into softer materials is desirable for drawing parts together quickly.
The screw is threaded two-thirds from the bottom, so the smooth upper shank lets the top piece slide while the threads grip the lower piece, helping pull components tightly together in assembly work.
The Wurth #8 x 1-1/2 flat head assembly screw uses #2 square drive bits, so a common square drive tip can be used for installing this fastener in cabinets or other assemblies.
The flat head assembly screw is meant to sit flush in a countersunk hole, letting the head pull surfaces tight while keeping faces smooth for later hardware, edging, or surfacing steps.
The screw is case hardened, so the outer surface is hardened for wear while supporting driving loads, which helps the head and drive recess resist deformation during repeated installations.
The Wurth assembly screw is provided in standard boxes of 1,000 and in bulk packs, supporting shops that use full box quantities and benefit from larger counts for recurring production runs.
The Wurth #8 x 1-1/2 flat head assembly screw, part number 3670000169961 5000, combines coarse threads, a sharp point, and #2 square drive in a case hardened design, so it fits everyday cabinet and woodworking assembly. The two-thirds thread layout on this length supports clamping between layers, while the lubricated surface helps the screw advance smoothly in repetitive driving. With full box quantities and bulk options under the Wurth Baer Supply fasteners line, this screw suits shops that standardize on a single assembly fastener across a wide range of projects.
