    Würth #8 x 1-1/2" Flat Head Assembly Screw Combo Drive - Sharp Point Coarse Thread Lubricated, 3670000409961 5000 - 5000/Box

    Description

    #8 x 1-1/2 Flat Head Assembly Screw Use

    #8 x 1-1/2 flat head assembly screw identifies this Wurth screw as a coarse-thread fastener sized for typical woodworking assembly, so installers can match common material thicknesses without rethinking their usual layouts. The flat head configuration allows the screw to sit flush when driven into a properly sized countersink, which helps assemblies pull up tight and keeps surfaces ready for edging or overlay work. Its sharp point coarse thread design bites quickly into wood-based materials, giving positive drive at the start of insertion and reducing walking at the hole location. The screw is case hardened, so the working surface of the shank and threads is hardened for driving performance while the core supports typical assembly loads. A lubricated finish is specified, which reduces driving friction and helps achieve consistent seating torque from one fastener to the next.

    Fastener Details That Support Woodworking Jobs

    • The Wurth brand designation ties this screw to a recognized woodworking fastener line, which helps shops standardize on a single source for cabinet and furniture assembly work.
    • The #8 diameter with 1-1/2 inch length provides a common size used in many wood construction situations, letting installers pair this screw with familiar pilot drilling patterns.
    • The flat head style works with countersunk holes so the head can sit below or flush to the surface, supporting clean installation under laminates or adjoining panels.
    • The coarse thread form combined with a sharp point cuts into material quickly, promoting fast starts and strong pull-down in typical wood substrates.
    • The lubricated description indicates a treated surface that aids driving, which can reduce driver bit strain during repetitive assembly cycles across many fasteners.
    • The designation as an assembly screw directs it toward joining components, helping users match it to carcass construction, stretchers, and similar joining tasks.

    Drive Style And Threading For Installation

    The web description notes that 3/4 inch and 1 inch lengths in this line are fully threaded, while all other sizes are threaded two-thirds from the bottom of the screw, so the 1-1/2 inch length sits in that two-thirds threaded group and behaves with a partially smooth upper shank. That layout allows the threaded portion to grip the base piece while the unthreaded section helps draw the top piece tightly against it during assembly. The same description specifies that #2 square drive bits are used to insert the screw in primary installation, which gives positive engagement between bit and recess during production driving. It also states that #2 Phillips drive bits can be used for after market adjustment, allowing installers or service technicians to drive or back out the screw later using a widely available Phillips bit.

    Using This Wurth Screw In Assembly Work

    Where This Coarse Thread Screw Fits Best

    This product is categorized by Wurth Baer Supply under fasteners and screws, positioning it squarely for use in woodworking and related shop assembly work. The SAP description "1-1/2x8,CRS,RECEX, FLAT LUBE" confirms a #8 size with coarse thread, which suits wood-based applications where holding power in softer substrates matters. The RECEX notation matches the combo drive description, aligning with the ability to drive using #2 square or #2 Phillips bits noted in the web description. As an assembly screw, it is oriented toward joining two components together rather than anchoring into masonry or metal, so it aligns with cabinet boxes, fixtures, or similar constructions made from wood or composite panels. The case hardened construction supports repeated driving loads during production runs, helping the screw stand up to powered insertions in shop environments.

    Details That Help Maintain Consistent Results

    The web description points out that #2 square drive bits are used to insert the screw, providing a drive style that helps reduce cam-out during production assembly, which in turn supports consistent head seating depth. The same description allows #2 Phillips drive bits for after market adjustment, so the combo drive recess remains serviceable with commonly carried tools in the field. The partially threaded form on this 1-1/2 inch length, based on the note that only 3/4 inch and 1 inch sizes are fully threaded, results in the upper shank helping to clamp the outer member to the base material once the threads engage, which promotes tight joints. The lubricated surface works with the case hardened body described in the product data, so driving torque stays manageable while the hardened exterior handles the bit load, supporting efficient workflow when many screws are driven in succession.

    Common Questions About This Wurth Assembly Screw

    What drive bits work with this combo drive screw?

    This Wurth assembly screw uses #2 square drive bits for insertion, and the web description states that #2 Phillips drive bits can be used for after market adjustment, giving flexibility in shop and field work.

    How is the threading arranged on the 1-1/2 inch length?

    The product line description says 3/4 inch and 1 inch lengths are fully threaded, while all other sizes, including 1-1/2 inch, are threaded two-thirds from the bottom, aiding clamping between joined parts.

    What does case hardened mean for this screw?

    This screw is case hardened, so its outer surface is hardened for driving and wear, while the inner core supports typical assembly stresses during cabinet and woodworking construction.

    Why use a lubricated finish on this assembly screw?

    The lubricated description indicates a treated surface that reduces friction while driving, helping installers seat heads consistently and maintain smoother driving torque over repeated use.

    What type of applications suit the coarse thread sharp point?

    The coarse thread and sharp point are described for this screw, which favors fastening into wood-based materials where quick starting and strong pull-down are important in assembly.

    How does the flat head design affect assembly work?

    The flat head design allows the screw to sit flush in a countersunk hole, helping assembled panels align cleanly and stay ready for edging, overlay, or adjacent component installation.

    Selecting This Screw For Wood Assembly Tasks

    This Wurth #8 x 1-1/2 inch flat head assembly screw combines a coarse thread, sharp point, case hardened body, and lubricated surface with a combo drive recess to support driven installation in wood-based assemblies. The threading layout for this length, with two-thirds threading from the bottom, works with the flat head design to pull components tightly together. For shops and installers needing a screw that aligns with #2 square drive insertion and #2 Phillips after market adjustment as described, this model offers a clearly defined option for repeatable cabinet and woodworking assembly work.
