Step 1: Define your buyer requirements

Get answers to these questions before you ask for a quote:

• Substrate: Both products below are described for concrete. Neither published description covers hollow block, brick or aerated concrete, so do not assume either one fits those materials.
• Load character: Is the fixing mostly static, under repeated vibration, or part of a seismic bracing system?
• Application: Is it a machine base, a steel column base plate, an infrastructure joint or outdoor equipment?
• Environment: Will the anchor be outdoors, exposed to moisture, or in a corrosive setting?
• Installation capability: Does the crew have standard rotary hammers only, or can it use special drill bits?
• Size and documentation: Which diameter and embedment are required, and which test or design references does your project specification call for?

Step 2: Compare the two documented options

Option A: Heavy Duty Concrete Anchors (fluted sleeve, ribbed shank)

The product description for Boen's Heavy Duty Concrete Anchors gives these features:

• Anti-rotation design: A fluted sleeve surface bites into the concrete to stop spin-out during tightening (the description cites ISO 16047). It states 95% torque retention, compared with 40–60% for smooth anchors.
• Vibration resistance: The description states the anchor withstands more than 10⁶ cyclic loads and references ISO 16130.
• Grip strength: A ribbed shank is described as raising pull-out resistance by 35%. The quoted test data is M10: 17.2 kN, against 12.7 kN for a smooth sleeve, with reference to ASTM E488.
• Corrosion protection: Zinc-plated carbon steel (ISO 4042 compliant per the description), with 500+ hours of salt spray resistance quoted under ISO 9227.
• Installation: Single-step expansion: drill, insert, tighten.
• Listed applications: High-vibration machinery (CNC bases, compressor mounts), steel column base plates (AISC 360), bridge expansion joints, seismic bracing, cell tower foundations and solar racking.

Best fit: Buyers who need heavy duty anchor bolts for concrete under vibration, such as machinery and conveyor bases, and who want a simple installation sequence.

Option B: Concrete Anchors (post-installed single-tube undercut)

The Concrete Anchors description covers an undercut anchor that works by mechanical interlock. Its published installation sequence is:

1. Drill the hole to the specified diameter and depth with a standard rotary hammer, then vacuum out the debris.
2. Expand the base cavity with an undercutting drill bit. The description says this step is mandatory for mechanical interlock.
3. Insert the anchor assembly until it is flush with the substrate surface.
4. Tighten the nut to 35 Nm to activate cone expansion.

Listed application areas include steel-to-concrete connections (steel column base plates per AISC 360, bridge bearing assemblies per AASHTO LRFD, precast wall connections per PCI Design Handbook) and seismic bracing (hospital equipment anchorage per IBC 1705.3, pipe and tray supports in earthquake zones).

Best fit: Structural steel-to-concrete and seismic bracing projects where the crew can carry out the extra undercutting step with the right drill bit.

Step 3: Match criteria to the application

When a recommendation does not apply

• If your substrate is not concrete, for example cinder block, brick or hollow masonry, neither description supports that use. Ask for a confirmed specification first.
• If the crew cannot use an undercutting drill bit, the undercut anchor's required installation step cannot be completed.
• For harsh corrosive or marine exposure, zinc plating may not be enough for your project's requirements. Confirm the coating and material with the supplier and your engineer.
• If your design needs load values for a diameter or embedment not covered here, do not take the M10 figures as representative. Request the matching spec sheet.

Step 4: Confirm before ordering

Both product pages say detailed specifications are available on request and spec sheets can be customized. Ask for:

• Available diameters, lengths and embedment depths for your size range
• Test reports behind the quoted standards and load figures
• Material and coating details, especially for the undercut anchor
• Installation torque and hole dimensions for each size
• Packaging and export documentation requirements

This guide does not confirm prices, lead times or certifications. Get those directly in your quotation, and have a qualified engineer check the final anchor selection for structural or seismic work.
