Solid fasteners
Works well on drywall. Would prefer if lengths were clearly marked on the box.
Description
These are zinc-plated, hardened steel self-tapping screws designed for fastening fiberboard and drywall materials. The cross flat head allows for countersunk installation, creating a flush surface finish, while the hardened construction ensures durability during insertion. Available in metric sizes M3, M3.5, M4, and M5 to accommodate various thickness requirements. Select the specific diameter that matches your pre-drilled hole or material density for optimal holding power.

Perfect for furniture assembly
Used these for assembling a new desk. The threads bite well into particleboard without stripping.

Good value for money
Screws are sharp and strong. Packaging was slightly crushed on arrival but contents were fine.
