Description

·Composed of screws,thrust sleeves,flat washers,spring washers,and nuts.After drilling straight holes in the concrete substrate,the bottom of the hole is en-bolt form an interlocking mechanism to achieve rear anchoring connection.

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>5um),suitable for ordi-nary environments

Hot dip galvanizing (zinc layer thickness>45um),applied in corrosiveenvironments

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