Concrete chemical anchor studs are made of carbon steel materials 4.8 - 8.8 grade with zinc plating, hot dipped galvanized or dacromet spray plating surface treatment.Providing external hex head, internal hex head and flat head types with the setting tools. Chemical anchor stud has high loading no radial influence of expansion force,allowed to be used close to foundation edges.
Chemical anchor stud is a kind of the fixings without expansion function used to fix the objects in the bedrock or concrete substrate. The chemical glass capsule for chemical bonding is a high load adhesive system,consisting of an outer glass container, liquid resin, hardener and quartz aggregate to forms a permanent bond between anchor stud bolt and the base materials.For installing, to comply with the corresponding curing time.
[Product features]:
※ Design external hex head, internal hex head and flat head types to use special setting tool for installing.
※ Made of carbon steel materials having 4.8-8.8 grade to realize various use purpose.
※ The sharp tail end make it insert chemical glass capsule and installing hole easier and quicker.
※ No expansion function.
※ Allow to use in the small space or edge of construction structure foundation.
※ Use chemical adhesive system for bonding between anchor stud and base materials in the hole to realize the fixing function, also called chemical adhesive anchors.
※ Mainly adopted chemical glass capsule or injection resin to achieve chemical bonding.
※ High loading performance and suitable for static and dynamic loading place.
※ Allow usage in damp installing hole.
※ Also used in reinforcement concrete construction structure for connecting or reinforcing.

[Installation Steps]:
❶ Drill hole in base material to ensure the proper hole diameter and depth.
❷ Use brush to remove the dirt and dust in the hole.
❸ Check the viscosity of the resin inside of glass capsule and insert a chemical glass capsule into a clean hole.
❹ Unscrew hex nut & washer to rotate threaded stud with setting tool and power tool to drive it into glass capsule till reaching the bottom of the hole.
❺ Observe the specified curing time until being solidified completely.
❻ Tighten hex nut and washer for fixing or reinforcing.
