	Avdel Speed Fastening: Chobert

The original speed fastening system used in a wide variety of materials.

Benefits:

Controlled Radial Expansion
A wide range of mandrel sizes enables Chobert^® to assemble the most brittle materials without cracking.
Tapered Bore
Internal taper creates greater expansion at the tail of the fastener, allowing joint tightness to be regulated.
Multiple Head Styles and Materials
Chobert^® fasteners are available in dome, low-profile and truss head styles, as well as aluminum, steel and brass materials.
