3.5 x 42mm Zinc Yellow Self-Drilling Drywall Screw

Summary

This 3.5 x 42mm self-drilling drywall screw features a zinc yellow (ZY) corrosion-resistant coating, designed for fixing plasterboard and drywall sheets directly to light-gauge steel framing without the need for pre-drilling. Its self-drilling point bites through metal studs cleanly, making it a reliable choice for drylining and partition wall installations. Supplied in trade quantities for site efficiency.

Features

• Self-drilling (Tek-style) point penetrates light-gauge steel framing without pre-drilling, speeding up installation.
• Zinc yellow (ZY) coating provides enhanced corrosion resistance compared to standard bright zinc plated finishes.
• Fine thread profile is optimised for securing plasterboard to metal stud partitions and ceiling systems.
• Trumpet (bugle) head sits flush with or just below the plasterboard surface for a smooth, ready-to-finish result.
• 3.5mm diameter and 42mm length suit single-layer plasterboard-to-metal-stud applications.
• Hardened steel construction ensures consistent drive and minimal cam-out during installation.
• Compatible with standard drywall screwdrivers and collated screw guns with depth-stop nose pieces.
• Suitable for use with Phillips or Pozidrive No. 2 bit.
