Sinsun long drywall screws are not an afterthought - they are a purpose-built component for complex wall and ceiling assemblies. The products we produce in our facility undergo rigorous testing to ensure they are tensile strong, coating-adhesive, and corrosion-resistant. As a result of this factory oversight, a 150mm screw performs similarly to a standard-length fastener, but with greater reach.
These screws answer the specific needs of commercial construction, renovation over existing surfaces, and specialized residential projects. Their design is a direct response to on-site challenges: the need to fasten through varying materials, to meet enhanced acoustic or thermal insulation requirements, and to ensure long-term stability in non-standard wall cavities. Sinsun: Fasteners Forged in Factory Precision. We provide the engineered solutions that allow builders to push the boundaries of modern construction, with confidence rooted in manufacturing excellence. Driven by Engineering, Backed by Proven Performance.
01
Project: Installing double-layer 13mm fire-rated board in a commercial kitchen ceiling with existing timber battens and thick insulation.
"Needed a screw that could go through 26mm of board plus 90mm of batt insulation and still get solid bite into the old hardwood joists. The 125mm length was spot on. They drove straight without bending and held rock solid. Saved us from having to add extra timber backing."
Project: Fixing new plasterboard over a traditional lime plaster and wood lath wall in a heritage townhouse.
"The existing wall was uneven, with a deep cavity behind the lath. Standard screws were useless. These 150mm drywall screws allowed us to secure the new board directly through the old system and into the solid masonry wall behind. They provided the incredible reach and holding power we needed without the need for destructive reframing."
Project: Creating a high-spec acoustic wall system (multiple board layers and resilient channels) in a recording studio.
"Precision in length was critical for our multi-layer assembly. The 120mm plasterboard screws were perfect for securing the final layer through the channel and into the primary steel stud. They were long enough for a deep, secure fix but not so long that they risked hitting pipes or wiring deep in the cavity. The consistency in length and drive performance was excellent for this sensitive job."
Q: What is a "large" plasterboard screw, and when do I need it?
+
A: "large drywall screws" usually means a thicker shank diameter, like #8 or #10 gauge. You need them for tough jobs like holding down thick or dense boards (like 5/8" fire-rated), double-layer systems or attaching plasterboard to soft or uneven wooden framing where extra pull-out strength is very important.
Q: What is the advantage of a large head (wafer head) drywall screw?
+
A: The oversized head provides a much wider bearing surface. This prevents the screw head from pulling through ("telegraphing") softer materials like thin plywood sheathing, OSB, or older, crumbly plaster. It's ideal for repair work, veneers, or low-density substrates where a standard bugle head would sink too deep.
Q: What do you use the Longest Drywall Screws for?
+
A: The longest screws, which are usually 3" to 6" long, are made for special framing situations. They are used to go through several layers of material (like plasterboard, rigid foam insulation and sheathing) or to reach deep into structural members (like solid timber beams or through furring channels) where standard lengths aren't long enough.
Q: What are the main uses for these long screws for plasterboard?
+
A: They are necessary for deep frame applications like attaching plasterboard to metal studs over thick thermal or acoustic insulation, making double-layer board systems for better fire ratings, and attaching boards to deep furring channels or uneven surfaces.

Q: What are the benefits of the factory-direct model for me as a contractor?
+
A: Sinsun controls the whole manufacturing process, which cuts out middlemen's markups and makes sure that quality control is always strict and consistent. This means that your business will always get reliable bulk prices and that every project, shipment after shipment, will have the same quality. Sinsun: Factory-made fasteners that are very precise.
Q: Can these screws be used on soffits outside or in other protected areas?
+
A: Our coating is better at resisting corrosion, but these are mostly made for framing and sheltered cavities inside. If your external fixtures are completely exposed, we suggest using our special exterior-grade screws with a weatherproof coating. Our technical team can help you choose the right fastener for your project. Driven by engineering and backed by proven results.
