Würth #10 x 3" Truss Head Installation Screw Phillips Drive - Needle Point Coarse Thread Zinc, 3670000242961 500 - 500/Box

Phillips Installation Screw For Thicker Stock and Deep Substrate Fastening

The Würth #10 x 3" truss head installation screw is a coarse-thread Phillips drive fastener built for securing cabinets, trim, and built-ins to wall framing and substrate materials. The 3-inch length reaches through finish panels and into framing or blocking, making it a practical choice when shorter screws cannot achieve adequate depth of engagement.

Key Features

• Truss head with a wide, low-profile bearing surface distributes clamping load without an oversized protrusion above the material face.
• #3 Phillips drive matches the larger drive size appropriate for a #10 gauge screw under installation torque.
• Needle point pierces finish panels and thin substrates cleanly without tearing the surrounding material.
• Coarse thread grips softwood framing, OSB, and engineered lumber for strong pull-out resistance.
• Zinc finish with sand-colored head helps the fastener blend with tan, beige, and sand-toned surfaces where head visibility matters.
• 500 screws per box supports production cabinet installs and multi-cabinet runs without frequent restocking.

Where the 3-Inch Length Earns Its Place

Installation screws at 3 inches are the right tool when the fastening path includes a finish panel, cabinet side, or substrate layer before reaching the structural material. Attaching wall cabinets through 3/4-inch plywood or MDF panels to wood studs, securing tall cabinets to blocking, and running screws through the nailer of a base cabinet into framing are all situations where a shorter screw leaves inadequate thread engagement in the framing. The 3-inch length clears those intermediate layers and puts thread into the wood that holds the load. The needle point starts cleanly in finish-grade materials, so the entry hole stays tight and the surrounding surface is not disturbed during installation.

Finish, Head, and Hardware Compatibility

The zinc finish with sand-colored head serves two purposes. Zinc provides standard indoor corrosion resistance appropriate for interior cabinet and millwork installation. The sand head color reduces visual contrast against tan or beige cabinet interiors, light-colored wall panels, and fiber cement or composite trim where a bright silver head would stand out. The truss head geometry keeps the bearing surface broad and the profile low, so the screw seats firmly without creating a prominent raised fastener in the finished space. This screw ships without nibs, so a countersink is not milled into the substrate as the head seats. For installations where the head must sit flush or below the surface, a pre-drilled countersink is the right preparation step.

Who Reaches for This Screw

Cabinet installers and finish carpenters working on kitchens, mudrooms, laundry rooms, and built-in millwork are the core users for this fastener. The 3-inch length and box quantity of 500 suit crews running multiple cabinets in a single visit, where consistency and speed matter more than specifying a different length for each cabinet position. The sand head finish also makes this screw a useful option for contractors installing trim or panels with tan or beige face colors, where a standard silver head would require touch-up or be visible through the finished surface.

Common Questions

The Right Length for the Full Stack

When the cabinet panel, nailer, and substrate all sit between the screw tip and the framing, the 3-inch Würth installation screw is the size that reaches the wood that holds the weight.
