Selectron 3.5x25 Coarse-Threaded Sharp-Point Drywall Screw (1,000 Pieces)

Selectron 3.5×25 Drywall Screw — Coarse‑Threaded, Sharp Point (1,000 Pieces)

The Selectron 3.5×25 mm Coarse‑Threaded Drywall Screw is a short‑length fastener specially designed for securing thinner drywall panels to wooden framing. Its coarse‑thread pattern grips wood fibres deeply to ensure a firm hold; with its sharp point, it installs quickly without requiring a pilot hole. At 25 mm in compact length, it is the ideal solution for 9.5 mm drywall and similar thin‑panel applications. The 1,000‑piece pack offers an economical, practical stock option for renovation teams, workshops, and suppliers.

Applications

• Fastening 9.5 mm thin drywall panels to wooden framing
• Joining drywall panels together and reinforcing joints
• Cladding applications on thin wooden batten and lath systems

Product Advantages

• Coarse‑thread design — grips wood fibres deeply, delivering high resistance to pull‑out and loosening over time
• Short 25 mm length — will not pass through thinner materials, delivering a clean, safe installation
• Sharp point — installs directly without pre‑drilling, saving time and labour on site
• Bugle head — seats neatly without damaging the drywall surface, leaving a perfectly smooth base ready for plastering
• Black phosphate coating — resists rust under indoor conditions; invisible beneath plaster and paint for a neat appearance
• PH2 Phillips drive — screwdriver bit seats fully with no slipping or wear, ensuring reliability in high‑volume applications
• Hardened steel — high resistance to bending and breakage; works comfortably with high‑speed screwdriving tools
• 1,000‑piece pack — convenient handling, cost‑effective pricing, and assured continuous supply

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 12–15 mm; the 25 mm length satisfies this requirement
• Not suitable for standard 12.5 mm drywall — select a 35 mm or longer model instead
• Not for steel profiles — coarse thread is designed for wood; use fine‑threaded or drill‑point variants for metal framing
• Do not over‑tighten — avoid pulling the head in so deeply that it weakens the material
• Storage — keep in dry conditions; stainless steel alternatives may be considered for consistently damp environments

Frequently Asked Questions

Can it be used on 12.5 mm thick drywall?
Not recommended — this model is made for 9.5 mm thin drywall or panel‑to‑panel joining; a 35 mm screw is suitable for standard thickness.

How does it differ from the fine‑threaded version?
Coarse thread provides deeper grip and higher pull‑out resistance in wooden framing; fine thread delivers more efficient hold in thin metal profiles.

Is a pilot hole required?
No — the sharp point allows direct driving into wood, significantly speeding up installation.
