Chobert®

Speed fasteners which provide consistent controlled clamp, ideal for soft or brittle materials.

Overview

The Avdel Chobert® speed fastener has been an important part of Avdel since the 1930’s when it was used in the renowned Spitfire. The Chobert Speed Fastening® system provides consistent controlled clamp, ideal for soft or brittle materials. The light clamp of the Chobert rivet makes it ideal for use as a pivot pin or hose tail.

Key features and benefits

  • Internally tapered bore ensures consistent light clamp to reduce potential damage to soft or brittle materials
  • Expands radially during installation to ensure maximum hole fill
  • Lower in-place costs than welding or nail rivets
  • Ideal pivot pin or hose tail
  • Hot tin dipped brass option for ease of soldering and good electrical continuity
  • Placed using a unique repetition mandrel system for high speed assembly
  • Can be bowl fed for larger volume applications using automated equipment
