Every major B+BTec Through-Bolt Anchor at a glance

We offer various types of through bolts, each with unique features for specific applications.

SMD version

Suitable for uncracked concrete and made from galvanised steel, hot-dip galvanised steel and stainless steel A4/316. Ideal for versatile fastenings in construction.

Advantages:

  • Time-saving thanks to through-bolt installation.
  • Three anchoring depths for maximum flexibility.
  • Distance mounting possible due to long thread.
  • With Typhoon dust extraction drills blowing out the drill hole is not necessary.
  • Suitable for timber construction thanks to the extra-large washer.

SMD-C version

Made from galvanised steel and hot-dip galvanised. Applicable for less critical fixings without approval requirements.

Advantages:

  • Suitable for less critical applications without testing requirements.
  • Minimal anchoring depth for faster installation.
  • Reduced risk of hitting reinforcement.
  • Distance mounting possible due to long thread.

SMD-CC version

Approved for cracked and non-cracked concrete. Available in galvanised steel, stainless steel A4/316 and sherardised steel. Ideal for heavy-duty and seismic anchoring.

Advantages:

  • Seismic approval (C1, C2).
  • Fire-resistant (R30-R210).
  • Two anchoring depths for optimal load.
  • Time and labour savings thanks to the Typhoon extraction drill.
  • Suitable for use in pressure-resistant natural stone.
  • Suitable for sprinkler system installations.

 

For which applications do I use each version?

Our anchors are used for anchoring medium to heavy loads in both cracked and uncracked concrete. Thanks to the various versions, they are widely applicable in the construction and installation sector. The most common applications are:

  • Surface-mount device (SMD):Suitable for uncracked concrete, ideal for timber constructions (in combination with a larger washer), struts, cable conduits, supports and brackets.
  • SMD-C:Applications without approval requirements, such as confirmations in less critical environments.
  • SMD-CCFor cracked and uncracked concrete, suitable for use in earthquake-prone areas, with approval for seismic activities (C1, C2). Applicable in steel support beams, railing fixings, consoles and structural reinforcements.
