Description
Composed of screws, trust sleeves, flat washers, spring washers, and nuts. After drilling straight holes in the concrete substrate, the bottom of the hole is enlarged again, and the enlarged cavity and the key plate that opens the anchor bolt form an interlocking mechanism to achieve rear anchoring connection

Base Material
Non cracking concrete,cracking concrete
Natural stone

Material quality:
4.8 grade steel, 5.8 grade steel, 8.8 grade steel, stainless steel 304(A2-70)/316(A4-80)
Surface treatment(excluding stainless steel materials): Electroplated zinc plating(zinc layer thickness>5μm), suitable for ordinary environments
Hot dip galvanizing(zinc layer thickness>45μm), applied in corrosive environments


Advantage:
Mechanical lock key effect, achieving shallow burial depth and high bearing capacity
Almost no expansion stress, suitable for anchoring with small edge distances
Can ensure the expansion plate to open to the maximum extent and achieve he ideal stress state
After installation, it can immediately withstand the maximum design load without waiting time(compared to chemical anchor bolts)
