Testing that Reaches the World
Anchors, Tie-Downs, Fasteners, Screws & Bolts
At Clark Testing’s ISO 17025-accredited Structures Lab, we specialize in precision testing of mechanical fasteners, including anchors, tie-downs, screws, bolts, and other critical hardware components. Our comprehensive structural load and fatigue testing services support construction, infrastructure, aerospace, and industrial applications. We simulate real-world field conditions to validate performance, durability, and safety. All testing is performed in accordance with ASTM, ACI, and ICC-ES standards to ensure regulatory compliance and long-term reliability of your fastening systems.
Our testing capabilities cover a wide range of fasteners and anchoring systems, including:
- Mechanical Anchors
- Concrete & Masonry Anchors
- Structural Screws & Lag Bolts
- Tie-Down Systems (Seismic, Wind Uplift, Shear Restraint)
- High-Tension Bolts and Fasteners
- Custom and Specialty Hardware
Clark’s structural testing services are performed to simulate real-use conditions, ensuring reliability and compliance:
- Cyclic Load Testing – Assesses performance under repeated loading
- Ultimate Fatigue Testing – Simulated load testing to specification and/or failure
- Creep & Long-Term Load Testing – Evaluates deformation over time under sustained load
- Environmental Conditioning – Exposes hardware to varying temperature, humidity, and corrosion for durability analysis
- Tensile Testing – Determines the pull-out strength and axial load capacity
- Shear Testing – Measures lateral load resistance
- Field Load Testing – On-site verification under actual installation conditions
