Hilti HSL4-G M10 Anchor Installation

Step 1a: Drilling

Drill a hole into the base material using a drill bit [drill] of diameter d₀ to the required depth h₁. Ensure the drill is held at a 90° angle to the surface. The diagram shows a standard drill bit and the anchor insertion process.

Step 1b: Core Drilling (Optional/Specific Cases)

For certain applications, a core drill bit [diamond drill bit] may be used. Drill a hole with diameter d₀ to depth h₁ at a 90° angle. This step may require a dust extraction system operating at 6 bar / 90 psi.

Step 1c: Anchor Insertion

Insert the HSL4-G anchor into the prepared hole. The diagram indicates the anchor's dimensions and the required hole diameter d₀, which can be 12 mm or 18 mm.

Step 2a: Bolt Insertion and Initial Setting

Insert the bolt through the fixture and into the anchor. Gently tap the bolt head with a hammer [hammer] to seat the anchor properly. A warning symbol [warning] indicates caution is needed.

Step 2b: Tightening the Nut

Place the nut onto the bolt and tighten it using an appropriate wrench.

Tighten the nut to the specified installation torque T_inst. The diagram illustrates the use of a torque wrench and shows the dimension a.

Verify the installation torque. The diagram shows '1x' for a recommended check and '2x' for a forbidden action [forbidden], implying a specific torque check procedure.
