2nd Bolt Connection

Conference 2014

The topics of the 2ndBolt Connection Conference 2014 deal with requirements, innovation as well as potential for technical optimization of bolt connections bigger than M20 (3/4 ’’) .

To optimize bolt connections and use their technical

potentials efficiently the whole picture of the “process

chain bolt connection” needs to be analyzed. The process

chain bolt connection consists out of the four factors

technical design, bolting method, fasteners used and bolt

integrity. This whole scale focus on bolt connection also

reflects in the titles of the speeches of the well known

German speakers.

Biggest optimization potentials can be identified among the

designing process of bolt connections and among bolt

integrity / quality. Therefore the 2nd Bolt Connection

Conference gives extra information on how to design bolt

connections more efficiently based on the updated

fundamental German bolting guideline VDI 2230.

Moreover there are projects presented about new

measurement technologies like the ultra sonic bolt

measurement to guarantee the integrity and durability of

bolt connections

Dipl.-Ing. Frank Hohmann,

Conference host

Target groups

The conference offers valuable information for engineers,

technical advisors, project engineers and technical deciders

who are working in sectors like technical design, research &

development as well as quality or project management –

generally every professional who deals with the design or

the use of bolt connections bigger than M20 (3/4’’).

Hands on tools on an extra dayThe extra day “hands on tools” on the day before the

conference gives a practical impression about the latest

innovations in bolting technology.

Organizer

ITHBolting Technology

Beeing the worldwide leading system supplier in bolting

technology it is the approach of ITH to give participants

additional values by mediating new technical knowledge.

This approach follows the ITH motto:

Technical efficient bolt connections must lead to

economical benefits for business partners.
