Würth #8 x 1-5/8" Flat Head Assembly Screw Phillips Drive - Type 17 Auger Point Coarse Thread Zinc, 3670000083961 3500 - 3500/Box

Wurth #8 x 1-5/8 Inch Assembly Screw For Woodwork

Wurth #8 x 1-5/8 inch assembly screw is a flat head, coarse thread fastener that tightens components while sitting flush in a countersunk hole, which helps create smooth cabinet or furniture surfaces that do not snag during daily use. The Phillips drive works with #2 Phillips drive bits, so installers can run these screws with standard drivers on site or in the shop without changing over to specialty bits. The Type 17 auger point starts quickly in wood, which supports faster driving and helps reduce splitting when running into typical woodworking materials. This screw is case hardened, which allows the outer surface to resist wear during driving in and backing out, helping maintain bit engagement over repeated installations. A zinc finish completes the screw, giving it a protective coating that supports general interior woodworking environments where corrosion resistance and a clean appearance both matter.

Key Screw Details That Support Wood Assembly

• The flat head design seats into countersunk holes, which allows workpieces to pull tightly together while leaving a flush surface that helps doors, drawers, or panels close without interference.
• The coarse thread profile matches typical wood and composite substrates, which lets the screw bite quickly and hold firmly in cabinet carcasses, face frames, and similar assemblies.
• The Type 17 auger point is shaped for easier starting in wood, which lets installers drive the screw more directly into material without extensive pre-drilling in many standard applications.
• The Phillips drive uses #2 Phillips drive bits, which matches common driver tips already in pouches and shops, supporting quick changeovers and consistent torque during assembly runs.
• The case hardened construction strengthens the screw surface, which helps the head and drive recess resist rounding under power drivers when seating joints tightly.
• The zinc finish provides a protective coating, which supports a clean, bright appearance in interior woodworking projects and helps the screw tolerate normal indoor moisture levels.

Installation Behavior Of This Flat Head Screw

This #8 x 1-5/8 inch flat head assembly screw uses a countersinking profile, which allows the head to draw down into prepared holes so parts clamp firmly together for accurate alignment of cabinet components. The coarse thread pattern engages wood fibers efficiently, which gives strong holding power in cabinet sides, stretchers, and face frames once driven to depth. With a Type 17 auger point, the screw enters material with a cutting action, which lets drivers advance the screw smoothly and helps limit wandering at the starting point. The Phillips drive interface is designed for #2 Phillips drive bits, which supports steady torque transfer from hand drivers or power tools during installation runs. Case hardened construction and a zinc finish round out the build, which provides a tough driving surface and a protected exterior suitable for common interior woodworking conditions.

Using This Wurth Screw In Cabinet And Wood Projects

Where This #8 Assembly Screw Performs Best

This Wurth #8 x 1-5/8 inch flat head assembly screw belongs in woodworking tasks where components need to pull tight and sit flush, such as cabinet boxes, furniture carcasses, and interior trim details. The flat head profile works with countersunk holes in rails, stiles, and panels, which helps panels sit even and leaves a smooth face ready for hinges or slides. Coarse threads are sized for wood and similar substrates, which gives a strong grip when joining cabinet sides to stretchers or braces. The Type 17 auger point brings a cutting tip to the screw, which supports confident starts into solid wood, plywood, or similar sheet goods used in the shop. With a zinc finish on a case hardened body, the screw is aligned with indoor woodworking environments where assemblies rely on consistent fastener performance over repeated usage cycles.

Why These Drive And Thread Details Matter

The Phillips drive sized for #2 Phillips drive bits ties directly to real installation speed, because installers can run this assembly screw using the same common bits already staged in their drivers. A flat head geometry that seats into countersinks lets the screw pull joint faces together, which supports accurate squareness in cabinet boxes and helps hardware mount flat against the work. Coarse thread spacing means fewer turns to develop holding power in wood, which shortens driving time across large production runs of similar casework. The Type 17 auger point helps the screw clear material as it advances, which supports smoother insertion and can reduce resistance as the screw nears full depth in typical wood substrates. Case hardened construction adds resistance to drive recess wear, which keeps the Phillips interface more consistent when driving multiple screws into dense areas. The zinc finish on the exterior contributes a protective and bright surface, which supports clean-looking fastening in visible or semi-visible interior locations.
