Wedge Mechanical Anchors: Maximum Strength for Structural Applications
Strong-Bolt® 2 and Similar Wedge Anchor Systems
Wedge mechanical anchors represent the gold standard for high-load applications in both cracked and uncracked concrete. These expansion anchors feature a wedging clip mechanism that locks securely into the concrete when proper torque is applied during installation.
Primary Applications:
- Structural steel baseplates and connections
- Heavy equipment mounting
- Industrial racking systems
- Safety barrier posts
- Critical structural attachments
Key Advantages: Fast, familiar installation process with broad size ranges available. Multiple finish options include zinc coating for standard applications, hot-dip galvanized for sill plates and treated lumber contact, and stainless steel (304/316 grades) for corrosive or exterior environments.

Concrete Screw Mechanical Anchors: Versatile Performance Solutions
Titen HD® Heavy-Duty Screw Anchors
The Titen HD® series delivers heavy-duty performance specifically engineered for cracked concrete and seismic applications. These thread-forming mechanical anchors eliminate the need for secondary expansion steps, allowing immediate loading after installation.
Ideal Applications: Structural attachments requiring seismic compliance, installations in cracked concrete substrates, and applications where removable or replaceable hardware is beneficial. View our full range of concrete anchors to compare Titen HD® options with other mechanical anchor types.
Titen Turbo™ Advanced Design Anchors
Representing the latest advancement in mechanical anchors technology, Titen Turbo™ anchors feature an innovative torque-reduction channel that enables smooth driving and faster installation in both concrete and masonry substrates.
Distinctive Features: Multiple head styles including hex heads for structural applications and flat/countersunk options for cleaner finished appearances. These mechanical anchors provide excellent performance in close edge and tight spacing scenarios where other anchor types may be limited.
Sleeve Anchors: Multi-Material Compatibility
Sleeve-All® Versatile Fastening Solutions
Sleeve mechanical anchors provide reliable medium-duty fastening across multiple base materials, making them ideal when substrate conditions vary throughout a project. The threaded stud design with expandable sleeve grips securely when the nut is tightened.
Compatible Substrates:
- Solid concrete
- Hollow concrete block (CMU)
- Brick and masonry
Common Applications: Handrail installations, light framing connections, electrical equipment mounting, shelving systems, and architectural fixtures.
Head Style Options: Available in hex, flat, and round head configurations to match specific hardware requirements and aesthetic preferences.
Drop-In Anchors: Clean, Flush Installation
Internally Threaded Expansion Anchors
Drop-in anchors provide flush-set, internally threaded expansion anchoring that sits below the concrete surface after installation. Installation requires a specific setting tool but results in a clean, professional appearance.
Optimal Applications:
- Threaded rod hangers and supports
- Trapeze systems
- MEP (mechanical, electrical, plumbing) supports
- Equipment mounting where flush finish is required
- Overhead installations
Benefits: Replaceable hardware capability, excellent for congested mechanical spaces, and professional finished appearance in exposed applications. For proper installation techniques, consult the International Building Code (IBC) requirements for structural anchoring applications.
Specialized Rod Hanger Systems
Titen HD® Rod Hangers
Purpose-engineered for creating load-rated attachment points for threaded rod, these specialized anchors excel in overhead suspension applications. Available in configurations for concrete/masonry (screw-anchor style) and structural steel (self-drilling/tapping or through-bolt options).
Standard Rod Sizes: Commonly available for 1/4″, 3/8″, and 1/2″ threaded rod applications.
Primary Uses:
- MEP support systems
- Trapeze and cable tray installations
- Conduit and ductwork supports
- Lighting system suspension
- Signage mounting
Installation Advantages: Fast, clean installation with immediate loading capability, compact low-profile head design, and fewer components to manage during overhead work. Many models carry approvals for cracked concrete and seismic applications.
Quick Selection Guide for Optimal Results
Choosing the right anchor depends on your specific application requirements:
For Highest Structural Demands: When dealing with cracked concrete or seismic requirements, select Titen HD® screw anchors or Strong-Bolt® 2 wedge anchors for maximum reliability.
For Fast Installation Projects: Titen Turbo™ and Titen HD® anchors provide quick installation with removable anchor capability and excellent performance in tight spacing or edge distance scenarios.
For Mixed Substrate Projects: Sleeve-All® sleeve anchors offer versatility across solid concrete, hollow masonry, and brick applications.
For Flush-Set Requirements: Drop-in anchors provide clean, flush installations ideal for overhead threaded rod applications.
For Light-Duty Masonry Work: Machine-screw and lead-style anchors handle utility fixtures and lighter loads effectively.
Critical Installation Requirements
Proper installation technique directly impacts anchor performance and safety. Never compromise on these essential requirements:
Drill Diameter Precision: Always use the exact drill bit size specified for each anchor type. Oversized or undersized holes significantly reduce capacity and reliability.
Thorough Hole Cleaning: For screw anchors and drop-in types, follow the blow/brush/blow cleaning sequence to remove all drilling debris and achieve full design capacity.
Embedment and Edge Distance: Meet minimum embedment depths and respect edge distance/spacing limitations to avoid capacity reductions that could compromise structural integrity.
Proper Torque Application: Apply manufacturer-specified installation torque values. Use impact tools for initial setting followed by final torque verification. Drop-in anchors require specific setting tools for proper installation.
Code Compliance: For structural applications, verify anchors carry appropriate ICC-ES or ETAg approvals for cracked concrete and seismic categories as specified by the Engineer of Record. Browse our concrete anchors catalog to find code-compliant options for your specific application.
Mechanical Anchors: Expert Application Matching Service
Selecting the optimal anchor system requires consideration of multiple factors including base material properties, fixture thickness, load directions, anchor sizing, and environmental conditions.
For complex applications or when specifications require verification, provide details about your base material type, fixture thickness, load requirements (tension/shear), anchor size preferences, and environmental conditions (interior, exterior, chemical exposure, coastal environments).
Simpson Strong-Tie’s technical support team can recommend the most appropriate anchor solution along with the correct drill bits, setting tools, and installation accessories needed for reliable, code-compliant installations.
Simpson Strong-Tie mechanical anchors provide proven solutions for demanding construction applications. By understanding the strengths and applications of each mechanical anchors family, contractors and engineers can specify and install fastening systems that deliver reliable, long-term performance across diverse project requirements.
