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

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

The Selectron 3.5×45 mm Fine‑Threaded Drywall Screw is a fastener specially designed for securing drywall panels to metal or wooden framing. Thanks to its close thread spacing, it grips drywall quickly, does not slip, and provides a firm hold. With its sharp‑point design, it penetrates easily even without a pre‑drilled pilot hole, shortening installation time. At 45 mm in length, it can also be used with confidence in double‑layer drywall applications. The 1,000‑piece pack offers a practical, cost‑effective solution for construction companies, renovation teams, and wholesale suppliers.

Applications

• Installation of single‑ and double‑layer drywall walls, ceilings, and partition walls
• Drywall fastening in wood‑framed systems
• Light steel construction systems with steel profiles

• Wall cladding, curtain wall systems, and interior partitioning
• Renovation, refurbishment, and repair work
• Mass housing, hotels, business centres, and public institution projects
• Continuous stockholding and bulk supply for construction teams

Product Advantages

• Fine‑thread design — grips drywall quickly, does not slip as the screw advances, strong holding power
• Sharp point — applies directly without pre‑drilling, significantly reduces labour time
• Trumpet head — countersinks neatly without breaking the drywall surface, leaving a smooth finish ready for plastering
• 45 mm length — provides sufficient depth for single‑layer drywall as well as double‑layer installations
• Black phosphate coating — corrosion‑resistant and invisible under plaster and paint
• Hardened steel — high resistance to breakage and bending; screwdriver bit does not slip
• Works in both wood and thin steel profiles — one screw type compatible with different framing systems
• 1,000‑piece pack — easy to carry on‑site, lowers unit cost, ideal quantity for project‑scale 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 by location — place at 30 cm intervals on ceilings, 40 cm intervals on walls
• Double‑layer applications — fasten each layer separately; screw length must pass through both layers
• Steel profiles — for profile thickness above 1.5 mm, select a suitable coarse‑threaded or drill‑point screw variant
• 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 ideal for wood framing; the coarse‑threaded type provides better grip in steel profiles.

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

Can it be used in steel profiles?
Yes, for material thicknesses from 0.75–1.5 mm; for thicker profiles, coarse‑threaded or drill‑point models are recommended.

How many layers of drywall will it secure?
Length suited to double‑layer applications using standard 12.5 mm boards.

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