Heat Treatment
Two Steps Heat-Treatment
1st step
Case Hardening
Case hardening on the head and shank of the screws with ductile strength, more endurable, and hydrogen embrittlement resistant characteristics.
2nd step
Selective Through Hardening
Selective through hardening to provide the drill point and lead threads with good drilling and tapping performance.

Installation Guide
Simple 4-Step Installation
Concrete screw anchors are designed for fast and reliable installation into pre-drilled holes in concrete.
-
STEP 1 — Drill
Drill the hole using the specified carbide drill bit.
-
STEP 2 — Clean
Remove dust and debris from the hole.
-
STEP 3 — Drive
Drive the anchor through the fixture into the concrete.
-
STEP 4 — Set
Install until the anchor head contacts the fixture. Apply recommended torque where required.
Installation Checklist
- Use the correct drill bit diameter.
- Drill to the required hole depth.
- Clean the hole before installation.
- Install perpendicular to the fixture surface.
- Do not over-drive the anchor.
