## Summary description

Celo self-drilling screws 4.8×16 mm are zinc-plated fasteners designed for direct fastening into metal without pre-drilling. CNBOP-certified and supplied in a pack of 250, these screws feature an integrated drill tip for efficient installation into thin sheet metal and metal profiles, suitable for construction, HVAC, and industrial assemblies.

## Long description

Celo self-drilling metal screws 4.8×16 mm are zinc-plated fasteners engineered for direct fastening into thin metal sheets and metal profiles without the need for pre-drilling. Supplied in a pack of 250, these screws include an integrated drill tip that cuts through steel and other common construction metals, offering consistent thread engagement and reliable holding power for a range of industrial and building applications. CNBOP certification indicates compliance with applicable safety and performance requirements for use in structural and technical installations.
Advantages
These self-drilling screws combine a corrosion-resistant zinc plating with a hardened drill point to simplify installation and reduce working time. The integrated drill tip eliminates the separate drilling step, while the uniform thread profile ensures secure fastening in thin gauge metal. Packed in a box of 250 pieces, they provide a convenient supply for medium-sized jobs and professional projects.
Suitable for
 Fastening thin sheet metal to metal supports
 HVAC ductwork and metal enclosures
 Installing metal roofing and cladding panels
 Light industrial assemblies and metal framing
 Repairs and retrofit work in construction
When it may not be suitable
These screws are intended for use with thin to medium-thickness metal where a self-drilling fastener provides sufficient pull-out and shear strength. They are not designed for load-bearing connections in heavy structural steel where specified high-strength bolts or welded connections are required. For very thick or hardened steel, pre-drilling or a specialized high-tensile fastener may be necessary.
Key specifications
 Size: 4.8 × 16 mm (diameter × length)
 Plating: zinc-plated for basic corrosion resistance
 Tip: integrated self-drilling point for direct installation into metal
 Material: hardened steel suitable for metal fastening
 Pack quantity: 250 pieces
 Certification: CNBOP certified for applicable safety and performance standards
How to use
Select the appropriate screw length for the combined thickness of the metal parts being joined. Use a compatible driver bit and power tool set to a controlled speed and torque to avoid stripping the head or damaging the sheet. Position the screw perpendicular to the metal surface and apply steady pressure while driving; the integrated drill point will penetrate and form threads as it advances. For thru-fastening, ensure the screw length provides sufficient engagement into the receiving material without excessive protrusion.
What to consider before purchase
 Confirm that 4.8 × 16 mm length is appropriate for the total material thickness
 Verify zinc plating provides adequate corrosion protection for the installation environment
 Ensure CNBOP certification meets the project or regulatory requirements
 Choose the correct driver bit and power tool capable of controlled torque
Usage recommendations
For optimal results, pre-align panels and use clamps to hold parts steady, drive screws at moderate speed, and inspect the fastening line for consistent penetration. In outdoor or corrosive environments consider alternative coatings or stainless steel fasteners if long-term corrosion resistance is critical.
