Wurth #8 x 3 inch washer head installation screw is a case hardened, coarse thread fastener in black and zinc finish that drives into wood and similar materials, giving installers a robust option for structural connections where grip and appearance matter. The washer head design spreads load over a larger surface area, helping the screw seat firmly against hardware or material surfaces to reduce pull-through on many installation tasks. The #8 size and 3 inch length combine to penetrate deeper material stacks while still working cleanly with common woodworking layouts. The sharp point works to start into material without pre-formed threads, helping the screw bite promptly into wood substrates. The black and zinc finish provides a dark, uniform look that visually blends with darker hardware and components while still reflecting the described coating properties during installation work.
The screw uses a #2 square drive bit for insertion, giving installers an established interface that helps engage driver bits securely during the main drive into wood or related materials. After market adjustment uses a #2 Phillips drive bit, so once hardware is in place the head accepts a common Phillips driver for minor repositioning or tightening. This dual-drive description means initial mounting and later adjustment can each use the drive style described for that step, which supports field workflows where access or tool choice shifts as trim, doors, or panels are added. Because the screw is case hardened with coarse threads, the driving and later adjusting both rely on a body that is designed for fastening tasks in cabinets, woodworking, or similar structures.
This Wurth washer head installation screw belongs to the screws class in the fasteners category, aligning it with tasks that demand secure joining of components in woodworking projects serviced by Wurth Baer Supply. The #8 x 3 inch size fits scenarios where a single fastener needs to reach through multiple layers, such as a hardware bracket, material panel, and underlying framing member in one drive. The coarse thread and sharp point support penetration into wood and comparable substrates, so the screw is positioned for use in cabinet construction, fixture mounting, or shop-built assemblies that rely on wood-based materials. The washer head profile presents a wide bearing surface that bears against hinge plates, brackets, or other fittings, helping distribute clamping force during those applications. The black and zinc finish coordinates with darker hardware systems in these environments, supporting projects where visible fasteners are part of the design.
The specified use of a #2 square drive bit for insertion gives installers a clear drive choice for the primary fastening step, which helps repeatable results when multiple screws are driven across a run of cabinets or components. Square drive engagement tends to hold the bit in place as torque is applied, which can support straighter driving into wood when aligning rails, brackets, or carcass parts. The after market adjustment using a #2 Phillips drive bit means that, once the installation is assembled, adjustments can be made with a widely carried Phillips driver on site. This is useful when front-facing access favors a Phillips tip for incremental tightening behind doors or trim pieces. The case hardened body works together with the coarse threads during both driving and adjustment, helping the screw stay seated under load as assemblies are fine-tuned. Each of these characteristics described in the product data supports consistent fastening behavior over repeated installations.
The screw is described as Wurth #8 x 3 inch with a washer head, so it matches layouts needing a #8 diameter fastener with 3 inch reach and a broad bearing head.
The screw uses a #2 square drive bit for insertion and a #2 Phillips drive bit for after market adjustment, giving two defined interfaces for mounting and later tuning.
The coarse thread advances quickly in wood and similar materials, helping pull components together efficiently and speeding the driving process on cabinet or fixture runs.
Case hardened describes a screw body treated for fastening tasks, supporting consistent driving and holding behavior during woodworking and cabinet assembly work.
The washer head spreads load over a wider area against hardware or material, helping reduce pull-through and supporting firm seating in many installation setups.
The black and zinc finish creates a dark, uniform appearance that coordinates with darker hardware assemblies where exposed fastener heads remain visible in finished work.
This Wurth #8 x 3 inch washer head installation screw combines case hardened construction, coarse threads, and a black and zinc finish with dual #2 square and #2 Phillips drive options, so it aligns well with wood-based installation work handled through Wurth Baer Supply. When projects call for a fastener that can reach through stacked materials, distribute force under a washer head, and still allow described after market adjustment, this screw offers a focused solution. Add it to layouts where consistent driving behavior, specified drive styles, and a dark head appearance all contribute to clean, repeatable installation results.
