Würth #8 x 1-1/2" Flat Head Assembly Screw Phillips Drive - Type 17 Auger Point Coarse Thread Black, 3670000071961 5000 - 5000/Box

Wurth Assembly Screw #8 x 1-1/2 For Woodwork

Wurth #8 x 1-1/2 inch flat head assembly screw is a case hardened fastener designed for assembly work where a flat head profile and coarse thread are preferred, so it suits many cabinet and woodworking fastening tasks. The flat head assembly screw seats flush in countersunk holes, which helps parts sit tight against each other without a protruding head interfering with adjacent components. Its #8 diameter paired with a 1-1/2 inch length gives a balance of bite and reach that supports joining common material thicknesses in assembly setups. The screw uses a Phillips drive, matching #2 Phillips drive bits, which is a familiar interface for installers and supports straightforward driving with standard tools. This assembly screw is part of Wurth Baer Supplys fasteners category, so it fits naturally into fastener selections focused on trade-oriented woodworking projects.

Practical Details Of This Wurth Assembly Screw

• The case hardened construction provides a hardened outer layer, which helps the screw withstand driving torque during installation in typical woodworking materials and supports consistent seating without deforming the head.
• The flat head design allows the screw to sit flush when driven into a properly countersunk hole, which keeps surfaces smooth in cabinet or furniture assemblies and reduces interference with moving parts or adjacent panels.
• The screw uses a Phillips drive that matches #2 Phillips drive bits, so installers can use widely available bits and drivers, simplifying tool selection and supporting consistent engagement during repeated fastening.
• The coarse thread form works together with the Type 17 auger point to advance quickly into material, which aids pull-down in many wood-based assemblies and supports efficient installation workflows.
• The black finish supplies a dark appearance on exposed heads, which can help the screw visually blend with darker components or hardware where the head remains visible after installation.
• The product is sold in full box quantities only, which suits production or shop environments where repeatable assemblies require consistent fastener supply for ongoing work.

Installation Characteristics And Threading Behavior

The Type 17 auger point helps the screw start into material efficiently, which supports smooth driving when beginning the hole in many assembly operations. Coarse thread on the #8 x 1-1/2 inch screw advances more aggressively than fine thread, helping the fastener draw parts together during installation and reducing time at each joint. According to the product description, 3/4 inch and 1 inch lengths are threaded fully, while all other sizes are threaded two-thirds from the bottom of the screw, so the 1-1/2 inch length uses this two-thirds threading from the tip upward. This threading pattern leaves an unthreaded section near the head, which helps the threads engage primarily in the base material, allowing the top component to clamp tightly as the screw is driven.

Using This #8 Assembly Screw In Wood Projects

Where This Wurth Assembly Screw Performs Well

This Wurth #8 x 1-1/2 inch flat head assembly screw sits within the screws class of fasteners, aligning it with general fastening tasks in woodworking and cabinet-related work. The flat head profile favors applications where the head needs to recess into a countersunk hole, such as joining cabinet parts or furniture components that require a flush surface. The black finish provides a dark head color, which can visually suit installations using darker materials or trim where a bright screw head would stand out. With coarse thread extending two-thirds from the bottom of the screw on this 1-1/2 inch size, the fastener is oriented toward engaging primarily in the thicker base piece, which supports clamping two layers when the top piece is unthreaded. The Type 17 auger point assists starting the screw into wood-based materials, which helps initiations in many assembly setups where pilot holes may be minimal.

Details That Support Consistent Assembly Results

The use of a Phillips drive sized for #2 Phillips drive bits means the screw interfaces with common drivers, which helps maintain consistent drive depth and reduces bit changes during production-style workflows. Case hardened construction supports the screw head and shank during installation by providing a hardened surface, which resists rounding of the Phillips recess under torque and supports reliable reuse of driver bits. The two-thirds coarse threading from the bottom on this length allows the unthreaded shank near the head to slide in the upper component while the threads engage in the lower piece, which improves pull-down of the joint as the head seats. The flat head geometry concentrates bearing under the head when seated in a countersink, which helps distribute clamping force around the top of the hole. Sold in full box quantities only, this fastener suits shops and installers running repeated assemblies who benefit from having the same screw on every joint for consistent results.
