Hilti HUS4-H(F) 10 Anchor Installation Instructions
This document outlines the correct installation procedure for the Hilti HUS4-H(F) 10 anchor system.
Product Overview
The Hilti HUS4-H(F) 10 is an expansion anchor designed for use in concrete. It is approved by ETA (European Technical Assessment).
Dimensions and Specifications
- Anchor Model: HUS4-H(F) 10
- Required Wrench Size: SW 15
- Maximum Material Thickness (tfix.max): Varies based on application (tfix.max1, tfix.max2, tfix.max3)
- Drill Hole Diameter (d₀): 10 mm
- Minimum Embedment Depths (hnom): ≥ 55 mm, ≥ 75 mm, ≥ 85 mm
- Minimum Hole Depth (h₁): L - tfix.max ≥ hnom.req
- Maximum Drill Bit Diameter (d): ≤ 14 mm
Installation Steps
Preparation and Drilling
- Step 1: Select the appropriate embedment depth (hnom) based on the load requirements. Ensure the drill hole diameter (d₀) is 10 mm.
- Step 2a: Drill the hole to the specified depth (h₁). The minimum hole depth must be greater than or equal to the required embedment depth (hnom.req) minus the maximum fixture thickness (tfix.max).
- Step 2b: Clean the drill hole thoroughly using a brush and vacuum or compressed air.
- Step 3a: Insert the HUS4-H(F) 10 anchor into the prepared hole.
- Step 3b: Use a hammer to gently tap the anchor until the collar is flush with the surface.
- Step 4a: Place the fixture onto the anchor.
- Step 4b: Screw the nut onto the anchor stud until it is snug.
- Step 5: Tighten the nut using the specified wrench (SW 15).
- Step 6: Ensure the anchor is properly set and the fixture is securely fastened.
Optional Steps and Considerations
- Optional: For specific applications, a maximum fixture thickness of 10 mm or 2x the fixture thickness may be applicable.
- Tool Compatibility: The installation may involve compatible Hilti tools such as SIW 6AT-A22, SIW 4AT-22, SIW 6-22, SIW 22T-A, SIW 9-A22, SIW 8-22.
Installation in Different Base Materials
Concrete Installation (Section C)
- C1: Ensure the concrete base material is suitable for anchoring. For example, concrete strength classes like PS 50, PS 300.
- C2: Maintain minimum edge distances and spacing between anchors. For a 10 mm diameter anchor (d₀ = 10 mm), ensure edge distances and spacing are at least 50 mm.
- C3: Insert the anchor into the drilled hole.
- C4: Tighten the anchor securely.
Important Notes
- Always refer to the specific technical data sheet for load capacities and application-specific requirements.
- Ensure all safety precautions are followed during installation.
- Use only approved Hilti accessories and tools for installation.
