Required Tools and Fasteners
- Anchor Types: HSW M12x220/60 8.8, M12x140 4.6
- Tools: SIW 6, SIW 8, SF 10W, T30 bit
- Fastener Clearance: 8 mm
Installation Procedure
Step 1: Hole Preparation
Drill a hole with a diameter of Ø 37 mm. Ensure a minimum embedment depth of ≥ 90 mm. Maintain a minimum edge distance of ≥ 54 mm. The required drilling depth is between 20-30 mm.
Step 2: Anchor Insertion
Insert the anchor into the prepared hole. Ensure the anchor is flush with the substrate surface.
Step 3: Fastener Installation
Use the specified HSW fasteners (M12x220/60 8.8 or M12x140 4.6). The anchor requires a 8 mm clearance hole for the fastener.
Step 4: Tightening and Verification
Use the appropriate tool (SIW 6, SIW 8, SF 10W with T30 bit) to tighten the fastener. Ensure a minimum material thickness (t₃) of 45 mm is maintained for secure fastening. Verify correct installation with a visual check. Incorrect installation is indicated by a red cross symbol ❌.
