Our Universal Wood Screws (4.8 x 100mm) are high-performance structural fixings designed for heavy-duty timber applications. Finished in a premium zinc and yellow passivation, these 100mm “gold” screws provide exceptional corrosion resistance and a deep, secure bite into softwoods, hardwoods, and masonry (with a plug).
100mm Extra-Long Reach: Ideal for fixing through thick timber sections, sleepers, and structural frames.
Zinc & Yellow Finish: Offers a double-layered protective barrier against rust, outperforming standard bright zinc.
High-Torque Pozi Drive: Features a deep No. 2 Pozi recess to prevent cam-out when driving into dense materials.

Universal wood screws of this length are specialized fasteners used for structural joinery and construction. The 100mm length is specifically engineered to pass through thick timber members—such as 50mm or 75mm joists—and provide significant embedment into the supporting structure. Whether you are constructing a timber deck, installing heavy-duty door frames, or securing internal studwork, these universal wood screws offer the pull-out resistance required for a permanent fix.
The “gold” appearance of these universal wood screws is the result of a zinc and yellow passivation process. This treatment is particularly important for 100mm screws, as they are often used in structural applications where they may be exposed to seasonal moisture. The yellow chromate layer provides a significantly higher level of salt-spray resistance than standard white zinc, ensuring the screw remains structurally sound and rust-free over decades of service.
At ECO HEAT SHOP, we provide fixings that are built for the rigors of the construction site. These universal wood screws feature a sharp 25-degree needle point for an immediate start and a single-thread geometry designed to clear wood waste as it drives. This reduces the friction and torque required to seat a 100mm screw, preventing the head from snapping and ensuring the timber does not split, even when working near the end of a board.

Usage Tip: When driving 100mm universal wood screws into hardwoods or very dry softwoods, we highly recommend drilling a 3.0mm pilot hole. This ensures the screw follows a straight path and reduces the stress on the screw head, providing a cleaner, more secure structural bond.
