Component Specifications

Definition
A complete assembly of threaded anchor bolts, nuts, washers, and sometimes anchor plates designed to permanently secure heavy machinery, structural components, or equipment to concrete foundations or floors. These sets provide critical load transfer from the machine to the foundation, resisting tensile, shear, and moment forces during operation and seismic events.
Working Principle
Works through mechanical interlock and friction. The bolt is embedded in concrete, and when tightened, it creates clamping force that secures the machine base. Expansion anchors use wedge or sleeve mechanisms that expand against the concrete hole walls when torque is applied, creating radial pressure and mechanical interlock. Adhesive anchors use chemical bonding between the bolt and concrete.
Materials
Typically manufactured from medium carbon steel (AISI 1035, 1045) or alloy steel (AISI 4140) with tensile strength 400-1000 MPa. Hot-dip galvanized, zinc-plated, or stainless steel (AISI 304, 316) for corrosion resistance. Nuts and washers matching bolt grade.
Technical Parameters
  • Length 150-1000 mm
  • Proof Load 70-90% of tensile strength
  • Anchor Type Expansion, adhesive, or cast-in-place
  • Thread Size M12 to M64
  • Torque Values 100-3000 Nm depending on size
  • Embedment Depth Minimum 8-12 times bolt diameter
  • Tensile Strength 400-1000 MPa
Standards
ISO 898-1, ISO 3506, DIN 931, DIN 933, ASTM F1554

Engineering Analysis

Risks & Mitigation
  • Improper installation torque
  • Insufficient embedment depth
  • Concrete cracking during installation
  • Corrosion in aggressive environments
  • Vibration loosening over time
  • Incorrect hole diameter
FMEA Triads
Trigger: Insufficient torque during installation
Failure: Bolt loosening under vibration, reduced clamping force
Mitigation: Use calibrated torque wrenches, follow manufacturer torque specifications, implement torque verification procedures
Trigger: Corrosion due to environmental exposure
Failure: Reduced cross-sectional area, potential bolt fracture
Mitigation: Select appropriate corrosion-resistant materials (stainless steel, hot-dip galvanized), apply protective coatings, regular inspection
Trigger: Concrete breakout during seismic events
Failure: Anchor pull-out from concrete, machine displacement
Mitigation: Proper edge distance calculation, use of supplementary reinforcement, seismic-rated anchor systems

Frequently Asked Questions

What is the minimum embedment depth for anchor bolts?

Minimum embedment depth is typically 8-12 times the bolt diameter for expansion anchors and 10-15 times for adhesive anchors, depending on concrete strength and load requirements.

How do I calculate the required anchor bolt size for my machine?

Calculate based on machine weight, operational forces (vibration, torque), seismic requirements, and concrete strength. Consider tensile, shear, and moment loads using engineering formulas or anchor manufacturer software.

What is the difference between expansion and adhesive anchors?

Expansion anchors create mechanical interlock through expansion against concrete. Adhesive anchors use chemical epoxy to bond the bolt to concrete. Expansion anchors are faster to install; adhesive anchors provide higher load capacity in cracked concrete.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
