Company Profile

Innovative Solutions

In recent years the market trend towards new materials used in assemblies such as composites, high-strength thin gauge
steels, and die-cast magnesium has presented new challenges to fastener manufacturers. Avdel® has been at the forefront of
new product development to meet these new market requirements during which time fasteners such as Versa-Nut® threaded
inserts, Maxlok® lockbolts, Rivscrew® PL, Klamp-Tite®, Bulbex®, and Avinox® rivets have all been developed as fastening
solutions for the changing market.

Double Flush Chobert® The Double Flush Chobert® rivet is a Speed Fastening® rivet with countersunk head for use
in exceptionally thin sheet materials. It is placed into sheets that have countersunk bores on
both sides. After installation, the placed rivet forms a flush fastening on both the front and rear
of the application.

Avibulb® XT & Avinox® XT High performance structural breakstem fasteners with excellent bulbing tail formation, featur-
ing a wide grip range.

Rivscrew® PL A proprietary Speed Fastening® System, combines the speed of rivet placement with the remo-
vability of a screw.

Avseal® II The new range of Avseal® II blind sealing plugs are unique in the efficient sealing performance
they provide in low and high pressure hole sealing applications.

Genesis® nG Range The new range of high performance, lightweight hydro-pneumatic handtools for breakstem
rivets.

Versa-Nut® The blind insert from Avdel® doubles the grip range of soft materials, thin wall plastics and
Large Diameter Avdelok® composites, while providing new levels of joint clamp and pullout resistance with fewer faste-
High Strength Hexsert® ners.

These lockbolts are heavy duty, two piece fasteners designed to provide exceptional high
strength, secure assembly. Quick and simple to place yet lasting for years, they are the ideal
solution where spot welding is not practical or possible.

The strongest material to eliminate cross threading. High strength Hexsert® provides clamp
force comparable to weld nuts and clinch nuts in high torque applications.

Avbolt® The Avbolt® structural blind fastener is a high strength, tamper resistant, blind steel
fastener designed for use in heavy duty structural applications such as construction,
6 container, railway and mining.

Speed Fastening® Systems

Benefits of assembly

Avdel speed fastening systems provide rapid and reliable assembly of metals, plastics, composites and passive electronic
components. The fasteners are either magazine-fed or fed via a vibrating bowl to a wide choice of installation equipment.
At the end of each assembly cycle, the next fastener is automatically delivered to the nose of the tool ready to repeat the
assembly process. Speed fastening offers many benefits over conventional mechanical assembly systems, including:

• High speed, blind sided assembly • Highly controlled assembly
• Consistent clamp and grip • Short cycle times
• Good vibration resistance • Elimination of over-torquing

Typical placing sequence 3. 1. The mandrel with pre-loaded
fastener is located in the hole.
1. 2.
2. Tool activation pulls the man-
drel through the fastener, expand-
ing it within the hole to provide
high clamp and secure joints.

3. At the end of the installation cy-
cle, the next fastener is automati-
cally delivered to the nose of the
tool, ready to repeat the assembly
process.

• Consistent high clamp • Quick and simple to install

Typical placing sequence

1. 2. 1. The fastener bolt is located in

3. the hole and the collar placed over
the stem. The tool is then located
onto the stem.

2. Tool activation pulls the
materials together and swages the
collar into the grooves of
the pin.

3. At a pre-determined load, the
stem breaks flush with the top of
the collar.

Blind Threaded Inserts

Benefits of assembly

Avdel threaded inserts and installation tools provide a quick, reliable and low cost system of inserting high quality, load
bearing threads. The inserts offer many benefits over weld nuts, self-tapping screws, pressed inserts and nuts & bolts.
Key user benefits include:

• Blind sided assembly • Lower cost of installation
• Reliable and secure thread installation • Suitable for use in stamped or drilled holes
• No damage to surface coatings • Designed for automation
• Reduced rework and wastage

Typical placing sequence The insert is threaded onto the
drive screw of the installation tool
Please visit our website www.avdel-global.com for fastener placing animations. and inserted into the prepared
hole in the workpiece.

On activating the tool, the threaded
insert is pulled towards the tool,
forming the body wall radially
outwards to clench tightly against
the workpiece.

At a pre-determined torque, the
drive screw of the tool reverses
and is disengaged from the thread,
leaving the insert securely in
position.

Assembly applications

Below are just a few examples of applications where Avdel threaded inserts provide the ideal fastening solution.

• Adjustable feet/castors Suspension damper Hydro formed cross beam Handrail
• Automotive components Automotive crash structure Washing machine
• Compressor units
• Computer chassis
• Door hinges
• Lawnmowers
• Lift cabins
• Number plates

Automation Systems

Customised Assembly Solutions

From simple twin-headed modules to multi-headed, customised equipment, these systems can dramatically reduce assembly
time and costs whilst improving consistency of placing.
Customised systems can be designed for virtually any application or assembly environment and process monitoring equipment
or clamping modules can be easily integrated. The direction, type and number of assembly heads can all be customised.
We have designed equipment with two heads to over eighty heads but the configurations are virtually limitless.

With assembly cycles as low as two seconds, these systems provide:

• High speed assembly • Highly controlled assembly
• Assembly of any configuration • Process flexibility
• Fastening at any angle • Integration into assembly lines
• Synchronous fastener placement • Improved product quality

Together with the fasteners, these high precision tools create a high quality, reliable assembly system. The fasteners are placed
accurately and consistently without the risk of over-torquing. An additional benefit of these systems are the practical jig points
provided by the assembly heads.
