Concrete chemical studs is a chisel cutting end chemical anchor fastener, used together with injection resin or chemical glass capsule to become chemical anchor system in the concrete, solid brick wall or stone places. For installing, threaded stud is chemically bonded to the base material.The chemical bolt fixing method imposes no expansion stress on the base material, and is ideal for shock or vibratory loading and for softer or low density building materials where expansion stresses would normally result in failure.  

    Chemical studs is made by the carbon steel materials 4.8-8.8 grade by hot dipped galvanized,having better rust proof and anti-corrosion performance than common zinc plating,suitable for wet or underwater installation pre-assembled hex nut and washer, providing the special setting tools.

[Product features]:

■ Hot Dipped Galvanized(HDG) have better rust proof and anti-corrosion performance than zinc plating.

■ Made of carbon steel materials having 4.8-8.8 grade to realize various use purpose.

■ No expansion function.

■ High loading performance and suitable for static and dynamic loading place.

■ Design external hex head, internal hex head and flat head types to use special setting tool for installing.

■ The sharp tail design make it insert chemical glass capsule and installing hole easier and quicker.

■ 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 adhesive anchor bolts.

■ Mainly adopted chemical glass capsule or injection resin to achieve chemical bonding.

■ Allow usage in wet or underwater installing hole.

■ Also used in reinforcement concrete construction structure for connecting or reinforcing.

[Hardening-setting time]:

[Installation Procedures]:

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.
