Application

Typically used to attach brackets, cleats, and support rails to box section steelwork or closed steelwork. Used in the following:

  • Metal roofing.
  • Cladding.
  • Facades.
  • Structural steel market.

Installation is carried out by inserting into pre-drilled steelwork and tightening with a torque wrench – see manufacturer's literature for further details.

Description

Steel bolting, used in applications where standard nuts and bolts aren't appropriate. During installation, the bolt sleeves expand whilst the grooves of the bolts interlock to prevent loosening. There are three variations of the bolt available – hexagonal, countersunk and flush fit.

A typical connection is made by inserting the Hollo-Bolt® into the pre-drilled holes of the fixture and hollow section. As the bolt head is tightened, the cone is pulled up the bolt thread, causing the sleeve to expand until the cone locks the sleeve against the hollow section’s inner wall.

Features and benefits:

  • Fast, cost saving installation from one side.
  • Suitable for square, rectangular and circular hollow sections.
  • High resistance to tension.
  • Patented, high clamping force design.
  • A range of head types for architectural finishes.
  • Manufactured in accordance with ISO 9001 and ISO 14001 Quality and Management Systems.
  • CE marked, and has approvals from DIBt, TÜV and ICC-ES Seismic.

Product Options

Size:

- M16/ M20 HCF:

Produces three times more clamping force than the same sized product without the mechanism. Suitable for higher strength structural connections. Consists of a special rubber washer that compresses during installation to significantly increase the clamping force between the connecting steelwork. Sizes M16 and M20 require the thickness of the outer ply to be at least 8 mm.
