ANCHOR

Rooty anchor C-D type (Hot-dip galvanization)

Nail-in anchor

  • ■Simply hammer in the pin. Just by looking at the pin, completion of an anchor can be confirmed.
  • ■Screw diameter and anchor unit diameter are the same, allowing for drilling after installation of equipment and anchoring without rattle.
  • ■The C-D type is dip-brazed, which is excellent in corrosion resistance.

Uses

Concrete

Installation method

  1. Drill a hole of a determined preparation hole diameter and depth from above the base material.
  2. Remove chips by dust collector or blower.
  3. Set the anchor and strike the pin with a hammer or the like.
  4. Tighten the nut with a spanner to complete the work.

Precautions on use

  • Protective clothing including safety glasses and helmets must always be worn when installing.
  • Drill perpendicularly into target surface.
  • Compared with anchor insertion depth, drill holes should be 5mm deeper for M6, M8, M10; 7mm deeper for M12; 10mm deeper for M16; 15mm deeper for M20.
  • Drilling preparation holes to shallow will break or bend a spindle.
  • Sufficiently use blower.
  • Always set nut before hammering.
  • Use a hammer appropriate for the anchor size.
