Self-cutting anchor bolt

Product Description

Application:
·Steel structure
·Safety handrail
·Staircases
·Machinery
·Cable troughs

Advantages:
·Rear expanding bottom anchor bolts in accordance with "Design Code for Reinforcement of Concrete Structures" GB50367-2013 and "Technical Specification for Post-anchoring of Concrete Structures" JGJ145-2013.
·Mechanical locking key effect for shallow burial depths and high load carrying capacity for maximum security.
·Almost no expansion force, especially suitable for anchoring with restricted edge spacing.
·Visual inspection of the marking lines ensures correct installation. -Installed and ready to carry the maximum design load without waiting time (compared to learnt anchors).

Function:

·Suitable for pre-insertion installation, penetration installation.
·After the installation torque is applied, the screw vertebrae is pulled into the expansion piece, which opens and presses against the hole wall.
·Once the mounting torque requirements are met, install in place.

Material:
·Electro Galvanised Steel
·Hot-dip galvanised steel
·Stainless Steel

Substrate:
·Cracked concrete/non-cracked concrete
·Natural stone

Class S anchor bolts:
·Tested by national authority
·Special Shield anchor bolts meet the requirements of Class S Ⅰ seismic performance requirements
