M16 Hollo-Bolt® Structural Expansion Bolt

M16 Hollo-Bolt® Structural Expansion Bolt

The M16 Hollo Bolt® features a high clamping force (HCF) mechanism suitable for the increased clamping force required of larger diameter bolts in structural applications. 

We recommend Hollo Bolts as a fast and effective solution for bolting structural hollow section (SHS) – eliminate the need for welding or access slots in SHS. Pre-drilled SHS structures can be delivered straight to site, the hollo bolts are simply inserted through pre drilled fixtures once aligned.

National Standards

Design to AS 4100 / NZS 3404 (Steel Structures) and ETA and ICC product certification.

Drill Preparation

Ensure that holes are drilled in both the fixture and the section according to the drilling guidance below. Please note that clearance holes are slightly larger than standard bolt clearance holes to accommodate the sleeve and cone.

Installation

  1. Align pre-drilled fixture and section and insert Hollo-Bolt*.
  2. Grip the Hollo-Bolt collar with an open ended spanner.
  3. Using a torque wrench, tighten the central bolt to the recommended torque**.

 

*Before tightening, ensure that the materials that are to be connected together are touching.

**See product brochure for correct tightening torque. Power tools, such as an impact wrench, may be used to speed up the tightening of the Hollo-Bolt. However, when using power tools, always complete the tightening process with a torque wrench to ensure the correct torque is applied to the Hollo-Bolt.
