UNIKA BG/BG-D Big One

Manufacturer: UNIKA
Model: BG type (Unichromate treatment)/ BG-D type (Hot-dip galvanizing treatment) Wedge: Stainless steel/ BIG ONE Hammering tool(Machine) [SDS type]/ Different diameter high nut for Big One (Unichrome treatment)/ Different diameter high nut for Big One (Stainless steel)

■Demonstrates reliable strength by installation through torque control and three-sided wedges.
■Demonstrates reliable installation strength with the torque control of the three-sided wedges. Installation can be done by either sides of the anchor as the diameter is the same.
■Overall length can be checked after installation by marking on the head.

USES

Concrete•Stone

Installation method

  1. Drill vertically to target surface with the determined preparation diameter and preparation hole depth.
  2. Use a dust collector or blower to thoroughly remove chips in the hole.
  3. Insert a big one.
  4. Hammer in until the washer contacts the installed object.
  5. Use a torque wrench to tighten the nut to the specified torque value.
  6. The three-sided wedge expands and installation is completed.

Precautions on use

  • Wear safety protection equipment such as protective glasses, a helmet etc., during installation.
  • Use a dust collector or blower to thoroughly remove chips in the hole.
  • Select overall length of anchor in consideration of thickness of installed object.
  • Align the end face of the nut with the end of the tape to set.
  • For installation, use a torque wrench to tighten to the specified torque.

Before installation

Install it after aligning the nut with the taper end section on the head of the anchor body.

Before installation

Installation check

If the thread section is protruded by a height of one nut or more when the nut is tightened, it has been improperly installed. Check the preparation hole diameter and install in another position.
