M5.5 Flat Head Torx Self Drilling Screw - A2 Stainless DIN 7504 Type "O"
Type "O" Refers to Countersunk Head Style (80° Degree)
How to Measure Length
Always measure countersunk screws from the top of the head to the end of the drill tip (overall length).
Which materials can this screw be used with?
Light Gauge Sheet Metal, 2mm - 6mm thickness
Wood / Timber, Engineered Wood, Composite Wood, Hardwood
Some plastics
What are the benefits of choosing this screw?
Drill-shaped point, eliminates need for pilot hole (saving time / money)
All “self-drilling” screws are considered “self-tapping”, but not all self-tapping are self-drilling
Why choose a Six-Lobe Torx Drive?
Torx drive screws provide higher torque transfer because the driving forces are transferred to each surface of the six lobes (wobble-free), instead of the four edges of the four edges on a phillips drive. Less overall force is needed to install these screws.
Material: A2 / SAE Type 304
A2 Stainless self drilling screws are commonly used on metal construction projects: residential and commercial exteriors, solar installation, decking, terraces, fences, exterior stairs, porch furniture, recreational / playground equipment, pergolas, facades, railings, architectural facades and finish work.
