Long-lasting outdoor performance - thanks to 304 stainless steel
Grade 304 stainless steel offers inherent resistance to rust and corrosion, keeping fastenings intact in damp or exposed environments. The material choice reduces surface oxidation over time.
Fewer replacements and reduced maintenance for fixtures exposed to weather, making the screws suitable for outdoor fittings and coastal installations.
Faster hand installation - with thickened butterfly handle and spiral head
Thickened handles increase the lateral bearing surface while the spiral, butterfly-shaped head improves grip during manual tightening. The ergonomic shape transfers hand torque more efficiently.
Quicker, tool-free fastening speeds up small installations and adjustments, ideal for jobs where power tools are inconvenient.
Reduced thread damage - thanks to clear threads designed to resist stripping
Clear thread profiles are manufactured to resist stripping under hand torque, improving engagement and reducing wear. Threads present consistent lead for reliable insertion.
Secure connections with a lower risk of rework or thread failure, useful when repeated removal and refitting are likely.
