Selectron 3.5x45 Drywall Screw, Coarse Thread, Sharp Point (1,000 Pieces)

Selectron 3.5×45 Drywall Screw — Coarse‑Threaded, Sharp Point (1,000 Pieces)

The Selectron 3.5×45 mm Coarse‑Threaded Drywall Screw is a professional‑grade fastener designed for securing standard‑thickness drywall panels to wooden framing. Its 45 mm length delivers the ideal depth to hold 12.5 mm thick drywall panels firmly to wooden battens. The coarse‑thread pattern grips wood fibres over a broader area, delivering exceptional holding power; its sharp point allows rapid installation without the need for a pilot hole. The 1,000‑piece pack offers a cost‑effective, practical solution for large‑scale projects, partition walls, and ceiling installation work.

Applications

• Fastening 12.5 mm standard‑thickness drywall panels to wooden framing
• Partition wall systems with timber framing
• Suspended ceiling cladding on wooden batten systems
• Double‑layer drywall installations and joint reinforcement
• Interior renovation and refurbishment projects
• Securing OSB, plywood, and similar boards to timber
• Home and workplace decoration, niches, and custom build applications
• High‑volume, continuous installation work for professional teams

Product Advantages

• Coarse‑thread design: Grips wood fibres deeply, offering high resistance to pull‑out and loosening; does not slip even in dense, hard timber species
• Ideal 45 mm length: Passes through 12.5 mm drywall + at least 20–25 mm into the wood; delivers full engagement without protruding through the back
• Sharp point: Installs directly without pre‑drilling; saves time and labour on site
• Bugle head: Seats cleanly without damaging the drywall surface; leaves a perfectly smooth base ready for plastering
• Black phosphate coating: Resists rust under indoor conditions; invisible beneath plaster and paint for a neat finish
• PH2 Phillips drive: Screwdriver bit seats fully; no slipping or wear, delivering 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 45 mm length easily satisfies this requirement
• Not for steel profiles — coarse thread is designed for wood; use drill‑point or fine‑threaded variants for metal framing
• Double‑layer applications — select a longer screw (55 mm or 75 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; prolonged damp exposure shortens coating life; consider stainless steel alternatives for consistently humid environments

Frequently Asked Questions

Can it be used in steel profiles?
Not recommended — coarse thread is optimised for wood. For metal framing, choose Selectron 3.5×45 Drill‑Point or fine‑threaded models instead.

Is 45 mm sufficient for 12.5 mm drywall?
Yes — the 45 mm length passes through the panel and penetrates approx. 25 mm into the wood, delivering ideal engagement depth.

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

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.

Are other lengths available?
Yes — the same series includes 25 mm, 35 mm, 55 mm and 75 mm models.
