    Würth #8 x 3" Washer Head Installation Screw Phillips/Square Drive - Sharp Point Coarse Thread Zinc, 3670000201961 1500 - 1500/Box

    Description

    #8 x 3 Washer Head Screw For Secure Installation

    #8 x 3 washer head installation screw gives you a long, case hardened fastener that bites firmly into material, so installed components stay tight under normal woodworking and construction loads. The washer head shape spreads the clamping force over a wider area, which reduces the chance of fastener pull-through on softer substrates. The screw uses a sharp point, so it starts into the work without a pilot in many materials, which helps speed up repetitive fastening. Coarse thread geometry advances quickly through stock, which reduces drive time per screw when running long rows. The screw is zinc finished, providing a protective surface that resists normal shop handling and typical indoor environments. This fastener sits in Wurth Baer Supply's fasteners and screws product class, so it fits directly into standard woodworking and cabinet assembly workflows.

    Key Installation Details For Daily Trade Use

    • Case hardened construction supports demanding fastening tasks by providing a tough, wear-resistant shank that holds up during repeated driving in wood applications.
    • Washer head design spreads load over a larger bearing surface, which helps parts sit flush and stay snug where smaller heads might sink or deform material.
    • Sharp point engages material quickly at the starting point, which reduces walking at layout marks and keeps rows of screws visually consistent along a line.
    • Coarse thread pattern advances rapidly through the work, which is useful when running many fasteners and helps maintain drive speed with fewer cam-out issues.
    • Zinc finish adds a protective layer on the screw surface, which supports long-term service in typical interior woodworking and cabinet shop conditions.
    • #8 diameter and 3 inch length give a balance of bite and reach, which lets you pull components together firmly where deeper embedment is required.

    Drive Options And Handling During Installation

    The screw uses a #2 square drive bit to insert, which gives positive engagement at the tool and helps transfer torque efficiently during initial installation. The same screw accepts a #2 Phillips drive bit for after market adjustment, so fasteners can be driven or backed out later using commonly carried Phillips drivers. This dual-drive arrangement helps crews handle both new installation and later service work without changing out all driving tools. The Phillips and square drive options match standard bits found in many professional and serious DIY setups, which streamlines on-site workflow and reduces time spent searching for a specific driver style.

    How This Wurth Installation Screw Fits Real Jobs

    Using The Wurth #8 x 3 Screw In Wood

    The Wurth #8 x 3 inch washer head installation screw sits in the Wurth Baer Supply fasteners and screws category, so it aligns naturally with cabinet, woodworking, and general installation tasks handled through that channel. Case hardened construction provides a robust body that tolerates driving into dense or layered materials where softer screws might twist. The coarse thread pairs with the sharp point, giving quick engagement and steady pull as the screw seats, which supports tight joints in thicker build-ups. The washer head profile creates a broad bearing ring against brackets or material faces, helping to distribute tension when pulling parts together. Zinc finish adds surface protection during handling, transport around the shop, and routine indoor service, so the screw maintains its function in a typical woodworking environment.

    Details That Support Consistent Installation Results

    The use of a #2 square drive bit for insertion lets installers apply torque with reduced bit slip, which helps hold alignment when driving near edges or in visible locations. After market adjustment with a #2 Phillips drive bit means the same installed screw can be serviced later with a widely available driver, supporting field adjustments without dedicated square bits. The 3 inch length offers substantial embedment into framing or backing material, so components can be drawn tight across gaps or shims. Coarse threads cut a firm path through the substrate, which supports a secure hold while keeping driving time manageable across large runs. The washer head geometry also helps hide minor irregularities in drilled or punched holes by covering a slightly oversized opening, which can be useful in retrofit or after-market adjustments where hole quality varies.

    Common Questions About This Wurth Screw

    What is the size and type of this Wurth screw?

    The screw is a Wurth #8 x 3 inch washer head installation screw, so it offers a moderate diameter with extended length for deeper fastening in typical wood assemblies.

    Which drive styles work with this installation screw?

    The screw uses a #2 square drive bit for insertion and a #2 Phillips drive bit for after market adjustment, which supports both high-torque driving and later service using common tools.

    How does the washer head design affect fastening?

    The washer head creates a broad bearing surface that spreads clamping force, which helps keep brackets or materials seated without the head digging deeply into softer substrates.

    What does case hardened mean for this screw in use?

    Case hardened construction provides a hardened outer layer on the screw, which improves resistance to wear and deformation during driving into dense materials.

    Why is the sharp point and coarse thread useful?

    The sharp point starts quickly into material and the coarse thread advances rapidly, which together speed installation while still pulling components tightly together.

    What role does the zinc finish play on this screw?

    The zinc finish forms a protective coating on the screw surface, which supports performance and appearance in typical interior woodworking and cabinet shop environments.

    Choose This Screw For Proven Wurth Installation Detail
