Würth #8 x 3" Flat Head Assembly Screw Phillips Drive - Type 17 Auger Point Coarse Thread Black, 3670000079961 2000 - 2000/Box

#8 x 3 Inch Flat Head Assembly Screw Use

#8 x 3 inch flat head assembly screw describes a case hardened fastener that handles demanding assembly work, so it suits applications where driving strength and wear resistance matter over time. The flat head design allows the screw to sit flush after driving, which helps parts pull tight without leaving a raised head that can interfere with adjacent components. The Phillips drive works with #2 Phillips drive bits, so installers can run these screws with widely used drivers and maintain bit consistency across similar jobs. The Type 17 auger point helps the screw start quickly and cut into material as it advances, which can reduce driving effort in many substrates. The coarse thread form engages material with fewer turns, so it advances faster through the workpiece while still providing strong holding power for assembly tasks.

Key Details That Affect Screw Performance

• The screw is case hardened, which gives the exterior a hard shell that resists wear during driving, supporting repeated bit engagement in production settings.
• The flat head assembly design allows the head to sit down into the work surface, helping parts pull together tightly where a flush or nearly flush finish is needed.
• The Phillips drive uses #2 Phillips drive bits, so installers can standardize on common bits across many fasteners and keep tool setups straightforward.
• The Type 17 auger point cuts as it enters, helping the screw bite into material quickly and advance with less resistance during installation.
• The coarse thread configuration advances more per turn than fine threads, which speeds driving while delivering strong grip for structural assembly connections.
• The black finish distinguishes this screw visually, which can help installers identify the correct fastener at a glance when sorting by finish on the job.

Installation Behavior, Drive Interface, And Fit

This screw uses #2 Phillips drive bits, so it works with a wide range of standard drivers and power tools in cabinet and assembly shops. The flat head geometry is intended to sit down into the material, which helps draw connected parts together as the screw seats. The Type 17 auger point assists with penetration, so the screw begins cutting into the substrate as torque is applied. The coarse thread form is designed to engage deeply with fewer revolutions, which can shorten drive time when running multiple fasteners in sequence. The case hardened construction supports the driving interface, because the hardened outer layer helps the Phillips recess maintain its shape during installation.

How This Wurth Screw Works In Assembly

Assembly Applications For This Phillips Drive Screw

This Wurth #8 x 3 inch flat head assembly screw is positioned for assembly work where a countersunk style head is desired, because the flat head shape lets the fastener sit low in the material. The Type 17 auger point supports applications where the installer wants the screw to start cutting into the substrate with the first turns, which can help during repetitive driving in shop environments. The coarse thread layout is suited to jobs that call for rapid advance and strong engagement in relatively few turns, which benefits installers driving many screws in succession. The black finish creates a consistent appearance where a dark fastener is preferred, which can matter when the head location is visible after installation. The case hardened construction supports assembly tasks that involve powered driving, because the hardened shell helps the screw tolerate the torque and repeated bit contact found in production workflows.

Details That Support Consistent Driving Results

The Phillips drive specified for this screw works with #2 Phillips drive bits, so installers can pair it with common drivers and maintain a predictable fit between bit and recess. The Type 17 auger point is designed to cut into the material as it advances, which can help the screw feed smoothly as torque increases and reduce wandering at the start of the drive. The coarse thread around the shank advances more with each turn, which supports consistent clamping force with less driving time per screw when fasteners are spaced along a joint. The flat head profile allows the screw to draw the upper piece firmly against the lower piece as the head seats, which helps achieve tight joints across multiple fasteners. The case hardened shell helps preserve the integrity of the drive recess and threads during installation, which supports repeatable seating performance on assembly lines or in larger project runs.

Common Questions About This Wurth Assembly Screw

Selecting This Screw For Assembly Projects

The Wurth #8 x 3 inch flat head assembly screw Phillips drive Type 17 auger point coarse thread black configuration is built for assembly tasks that rely on #2 Phillips drive bits, a flat seating head, and case hardened construction. The Type 17 point, coarse thread, and black finish work together to support quick driving, strong engagement, and a dark head appearance where that look is preferred. When selecting fasteners for assembly work where flush seating and efficient powered driving are important, this screw provides a clearly defined combination of drive style, point design, thread form, and finish that aligns with those needs.
