Unlike other concrete screws that sacrifice hardness for corrosion resistance, Anzor’s Hardtec Concrete Screws are hard enough to cut threads into concrete whilst maintaining high corrosion resistance.
High corrosion resistance
Greater corrosion resistance than 304 SS and 410 SS.
High Strength
6.8kN (average characteristic pull out)
15kN (average characteristic shear load)
Screws tested in 34.4MPa concrete with 30mm embedment depth
Hardness
Hardtec Concrete Screws are 50% harder than 304 SS. Unlike most stainless steel grades, this enables the screws to easily cut threads into concrete.
HWF and Csk sizes
6mm x 40mm - 6mm x 50mm - 6mm x 75mm
Advantages
• T30 Star Drive allows for better drive engagement.
• A standard 5.5mm masonry drill bit can be used thus eliminating the need to purchase a new box of screws just to obtain a new drill bit.
