Selectron 3,5x35 Coarse-Thread Sharp-Point Drywall Screw (1,000 Pieces)

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

The Selectron 3.5×35 mm Coarse‑Threaded Drywall Screw is a fastener specially designed for securing drywall panels to wooden framing. Its coarse‑thread pattern grips wood fibres deeply over a wide span, delivering exceptional holding power; with its sharp point, it installs directly without needing a pilot hole. At 35 mm in length, it is the ideal size for single‑layer drywall applications. The 1,000‑piece pack offers an economical, practical solution for construction teams, renovation companies, and wholesale suppliers.

Product Advantages

• Coarse‑thread design — grips wood fibres deeply, offering high resistance to pull‑out and loosening over time
• Sharp point — installs directly without pre‑drilling, saving time and labour on site
• Bugle head — seats cleanly without damaging the drywall surface, leaving a perfectly smooth base ready for plastering
• Ideal 35 mm length — passes through 12.5 mm drywall + at least 20–22 mm into the wood; delivers full engagement without protruding through the back
• Black phosphate coating — resists rust under indoor conditions; invisible beneath plaster and paint for a neat finish
• PH2 Phillips drive — screwdriver bit seats fully with no slipping or wear; delivers reliability in high‑volume applications
• Hardened steel — high resistance to bending and breakage; suitable for use with high‑speed screwdriving tools
• 1,000‑piece pack — enables uninterrupted work on large projects; lower unit price makes stocking economical

Installation & Assembly Recommendations

• Drive the screw perfectly perpendicular to the panel; angled entry reduces contact area and increases risk of panel breakage
• Ensure the head sits flush with the surface; do not drive too deep and tear the paper facing
• Edge distance — install screws no closer than 10–15 mm from the panel edge; prevents edge cracking
• Penetration depth in wood — minimum 20 mm; the 35 mm length easily satisfies this requirement
• Not for steel profiles — coarse thread is designed for wood; use Selectron fine‑threaded or drill‑point variants for metal framing
• Double‑layer applications — select a longer screw (45 mm or 55 mm) when installing the second layer
• Do not over‑tighten — avoid pulling the head so deep that it weakens the material
• Storage — keep in dry conditions; consider stainless steel alternatives for consistently damp environments

Frequently Asked Questions

Can it be used in steel profiles?
Not recommended — coarse thread is optimised for wood. For metal framing, choose Selectron fine‑threaded or drill‑point models.

Is 35 mm sufficient for 12.5 mm drywall?
Yes — the 35 mm length passes through the panel and penetrates approx. 20 mm into the wood, delivering ideal holding depth.

How does it differ from the fine‑threaded version?
Coarse thread provides deeper grip and higher pull‑out resistance in wooden framing; fine thread is better suited to thinner drywall and steel applications.

Is a pilot hole required?
No — the sharp point drives directly into wood, significantly speeding up installation.

Are other lengths available?
Yes — the same series includes 25 mm, 45 mm, 55 mm and 75 mm models.

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