Product Description
Screw Anchor
1. Features and advantages
1. Suitable for cracked and non-cracked concrete
2. Can be used for small margin and narrow pitch applications
3. Set the buried depth marking line to ensure that the anchor bolts are installed correctly
4. Provide reliable installation instructions
5. Complete design, convenient installation
6.8.8 level mechanical properties, superior tensile, shear, fatigue and fire resistance
7. The surface is electro-galvanized 8um, the color is bright and slightly blue; the hot-dip galvanized 55um, the bolts and nuts are screwed smoothly
2.Installation diagram (no need for reaming, only drill bit is needed to drill, use standard button to install, achieve better after tracing effect)
3.Bearing capacity values and installation data of anchor bolts of different diameters in cracked concrete and non-cracked concrete
