The first Radium designed fasteners.

Countersunk screws are our favorite due their low profile and versatility. However normal M5 countersunk screws have one main drawback - they only support a 3mm Allen key hex which is prone to stripping. Our unique design provides a stronger head allowing for the same 4mm hex that M5 cap screws use, meaning our Ti screws will last a long time.

You'll also find a 14mm straight shank on these screws to maximize strength where its needed most, instead of having threads in this area which can lead to fatigue cracking.

The head sits slightly proud above the mounting surface, showing off more of the titanium, and protecting your deck or anti-sink hardware from flipping damage.

• High strength custom head design that supports a larger 4mm hex
• 14mm straight shank to provide maximum strength where its needed
• One screw weighs 3.2 grams
• Price is for 4 screws and 4 steel lock nuts (Ti nuts are not used due to their tendency to cold weld to Ti fasteners)
