Spax Self-Drilling Screws M SK T15 3.5x50 mm – Zinc-Plated Part-Tread Fasteners for Demanding Applications
The Spax Self-Drilling Screws M SK T15 3.5x50 mm are precision-engineered fasteners designed for direct drilling into metal and other materials without pre-drilling. With a part-thread design and T15 Torx drive, they deliver reliable holding power in structural and industrial assemblies.
Part-thread design provides secure grip in thin to medium-gauge metals
T15 Torx drive ensures high torque transmission and reduces cam-out risk
Zinc-plated surface offers corrosion resistance for indoor and outdoor use
Self-drilling tip eliminates the need for pre-drilling, saving time on the job
The combination of a self-drilling point with a part-threaded shank makes these screws suitable for applications where a separate pilot hole would otherwise be required. The zinc plating adds a layer of protection against rust, extending the service life of the fastener in varied environments.
Ideal for...
Metal framing, roofing, cladding, and general construction tasks where fast, reliable fastening into metal profiles is needed. Also suited for workshop and industrial assembly work where efficiency and joint durability matter.

Spax is a specialist fastener manufacturer known for self-drilling and self-tapping screws used in metal construction, roofing, and industrial assembly. The brand focuses on precision-engineered fasteners with reliable holding power and corrosion-resistant surface treatments.
A self-drilling screw has a pointed tip that bores its own hole as it is driven into the material, eliminating the need for a separate pilot hole. The part-threaded design engages the material securely as the screw advances.
These screws are designed for metal applications, including steel profiles, sheet metal, and light-gauge metal. They are not intended for wood, plastic, or masonry without a pre-drilled hole.
The T15 Torx drive provides a high torque transfer with reduced risk of cam-out compared to standard Phillips or slotted drives. It requires a matching T15 Torx bit for installation.
The delivery includes 200 pieces of Spax Self-Drilling Screws M SK T15 3.5x50 mm, zinc-plated, in a single pack.
Spax provides a 24-month manufacturer warranty on these fasteners, covering defects in material and manufacturing under normal use.
