Selectron 3.5x35 Fine-Thread Sharp-Point Drywall Screw (1,000 Pieces)

Selectron 3.5×35 Drywall Screw — Fine‑Threaded, Sharp Point (1,000 Pieces)

The Selectron 3.5×35 mm Fine‑Threaded Drywall Screw is a fastener specially developed for securing drywall panels to wooden framing. Thanks to its close thread spacing, it grips the panel quickly, does not slip, and provides a firm hold. With its sharp‑point design, it penetrates easily even without a pre‑drilled pilot hole, reducing installation time on site. At 35 mm in length, it is the ideal size for single‑layer drywall applications. The 1,000‑piece pack offers a practical, cost‑effective solution for construction teams, renovation companies, and wholesale suppliers.

Applications

• Installation of single‑layer drywall walls, ceilings, and partition walls
• Fastening drywall in wood‑framed systems

Product Advantages

• Fine‑thread design — grips drywall quickly, does not slip as the screw advances, provides a secure hold in wood
• Sharp point — drives directly without pre‑drilling, eliminating time lost on site
• Trumpet head — countersinks neatly without breaking the drywall surface, leaving a smooth finish ready for plastering
• Ideal 35 mm length — sufficient depth for standard 12.5 mm drywall panels, will not protrude through the back
• Black phosphate coating — corrosion‑resistant and invisible under plaster and paint
• Hardened steel — high resistance to breakage and bending; screwdriver bit does not slip
• Also suitable for light steel profiles — one screw type works in non‑wood framing too
• 1,000‑piece pack — easy to carry on site, lowers unit cost, ideal quantity for daily use

Installation & Assembly Recommendations

• Drive the screw perfectly perpendicular to the drywall surface; angled entry weakens the hold and may fracture the panel
• Ensure the head sits flush with the surface; advance gently so as not to crush the drywall
• Edge distance — install screws no closer than 15–20 mm from the panel edge
• Screw spacing — place at 30 cm intervals on ceilings, 40 cm intervals on walls
• Depth in wooden framing — screw must penetrate at least 20–25 mm into the wood for adequate holding power
• Double‑layer applications — select a longer screw (45 mm or 55 mm); this model is designed for single‑layer use only
• Do not over‑tighten — avoid driving the head so deep that it weakens the drywall
• Store in dry conditions; prolonged exposure to moisture shortens coating life

Frequently Asked Questions

How does it differ from the coarse‑threaded version?
The fine‑threaded variant is designed primarily for wood framing; the coarse‑threaded type provides better grip in steel profiles.

Can it be used for double‑layer drywall?
No — this model is ideal for single‑layer (12.5 mm) applications; for double‑layer, a 45 mm or longer screw is recommended.

Is a pilot hole required?
No — the sharp point allows direct installation, saving time on site.

Will it rust?
Phosphate coating is sufficient under normal indoor conditions; for permanently damp environments or outdoor use, choose stainless steel versions.

What is the difference vs the 45 mm version?
35 mm is for single‑layer installations; 45 mm is the appropriate length for double‑layer or thicker framing applications.
