Selectron 3,5x45 Drill-Point Drywall Screw (1,000 Pieces)

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

The Selectron 3.5×45 mm Drill‑Point Drywall Screw is a professional‑grade fastener specially designed for securing drywall panels directly to steel‑framed structures. Its drill‑point design cuts through steel up to 2.0 mm thick without the need for pre‑drilling, shortening labour time. The fine‑thread profile delivers high holding power on steel. At 45 mm in length, it can be used reliably for both single‑ and double‑layer drywall applications. The 1,000‑piece pack is the ideal solution for construction firms, ceiling specialists, and wholesale suppliers.

Applications

• Fastening drywall panels to light‑gauge steel framing systems
• Installation of single‑ and double‑layer drywall walls, ceilings, and partition walls
• Suspended ceiling systems and concealed thermal insulation applications
• Cladding systems and interior partition walls
• Finishing work for offices, business centres, and commercial spaces
• Mass housing and public‑sector projects
• Interior cladding for prefabricated buildings with metal framing
• Renovation and refurbishment work with steel framing

Product Advantages

• Drill‑point design — self‑drills through steel sections without pre‑drilling, saving time and labour on site
• Fine‑thread profile — closer thread spacing creates more engagement points on steel; resists slipping and loosening
• 45 mm length — ideal depth for single‑layer 12.5 mm drywall + steel connection; sufficient for double‑layer applications too
• Bugle head — seats cleanly without damaging the drywall surface, leaving a perfectly smooth base ready for plastering
• PH2 Phillips drive — screwdriver bit seats fully with no slipping or wear, ensuring reliability in high‑volume applications
• Black phosphate coating — resists rust under indoor conditions; invisible beneath plaster and paint for a neat appearance
• Hardened steel — resists wear during drilling; high resistance to bending and breakage
• 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 drilling efficiency and weakens hold
• 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
• Section thickness — suitable for direct installation up to 2.0 mm; pre‑drilling is recommended for thicker sections
• Fastening tool — use a driver with adequate torque and speed; low rotation speeds cause the point to overheat and reduce efficiency
• Not recommended for wood framing — coarse‑threaded sharp‑point models perform better in timber applications
• Do not over‑tighten — avoid pulling the head so deep that it weakens the drywall
• Storage — keep in dry conditions; select stainless steel versions for permanently damp or outdoor environments

Frequently Asked Questions

How does it differ from the sharp‑point version?
Drill‑point screws cut through steel themselves; sharp‑point types require pre‑drilling and are better suited to wood framing.

Can it be used in wood?
Not recommended — the fine‑thread design does not provide sufficient grip in wood; choose coarse‑threaded sharp‑point models for timber.

What is the maximum steel thickness it can handle?
Designed for direct installation up to 2.0 mm; manufacturer confirmation or pre‑drilling is advised for thicker sections.

Is it sufficient for double‑layer drywall?
Yes — the 45 mm length passes through two 12.5 mm drywall sheets and provides secure engagement in the steel section.

Will it rust?
Phosphate coating is adequate for indoor conditions; stainless steel versions are available for consistently damp or outdoor exposure.
