Six things you'll be able to do on Thursday morning

This is a working session for engineers, not a product pitch. Everything below is covered with a GEOMET® 500 + PLUS M system as the worked example.

Read a torque-tension curve properly

Separate µ_total, µ_thread and µ_head, and understand what the scatter band is telling you about the coating and the joint.

Set a COF window a supplier can hold

Where to place the window for your part, how wide it needs to be, and what a needlessly tight window costs you in price and rejection.

Recognise four failure signatures

Loosening in service, bolt yield, thread stripping and unexplained line rejections — and how to trace each one back to friction instead of guessing.

Know which parameters move COF

Topcoat film weight, cure profile, application method and coating uniformity — what genuinely shifts friction batch to batch, and what does not.

Run and document the right test

ISO 16047 setup, a sampling frequency that survives an audit, and the records to retain for traceability with your customer.

Get your own problem answered

Bring a joint that is misbehaving. Thirty-five minutes are reserved for you to put it to the NOF technical team, live.

Answered by the people who develop the chemistry

GEOMET® is developed by NOF Metal Coatings Group. For this session their technical teams in France and Japan join Aum Dacro Coatings, who apply the system across four plants in India.

🇫🇷 NOF Metal Coatings Europe, France

Lead technical speaker

Name and designation announced shortly

Delivers the 60-minute technical session. The European laboratory works directly with vehicle manufacturers and fastener producers on torque-tension behaviour, COF window definition, and the failure investigations that follow when a window is missed. This is where the GEOMET® and PLUS topcoat systems are developed and qualified against OEM specifications.

🇯🇵 NOF Metal Coatings Asia Pacific, Japan

Technical panellist, live Q&A

Name and designation announced shortly

Joins the open floor. The Asia Pacific team supports licensees across the region and sees, every week, how friction requirements differ between Japanese, European and Indian OEM specifications — useful if you supply into more than one of them.

Three things about friction that surprise most specs

A preview of the physics the session is built on.

90%

Almost none of your torque becomes clamp load

Around nine-tenths of the torque you apply is spent overcoming friction under the bolt head and in the threads. What is left holds the joint together.

33%

A small drift in µ is a large drift in preload

Two bolts, same wrench, same torque setting: move µ_tot from 0.10 to 0.16 and clamp load can fall by roughly a third. Nothing on the shop floor looks any different.

4

Friction is not a property of the coating

Four things change µ without anyone touching the coating: the mating nut, the counter surface, the tightening speed, and how many times the joint has been tightened before.

Two hours, three blocks

12:30 PM IST25 min

The applicator's view

Aum Dacro Coatings on zinc flake and topcoat systems in Indian production, and how customer torque-tension requirements reach the coating line.

12:55 PM IST60 min

COF, start to finish

NOF Metal Coatings Europe on fundamentals, measurement, anonymised failure cases from automotive fasteners, and process control that holds the window.

1:55 PM IST35 min

Live Q&A

Open floor with the NOF technical teams from France and Japan. Questions submitted at registration are taken first.

Bring one question. Leave with an answer.

Thirty-five minutes is a third of the session, and it is the part we protect. Most engineers never get to put a friction problem directly to the people who formulate the coating.

›Submit your question in the registration form — those go to the panel in advance and are answered first.
›Ask about your own part, your own spec, your own failure. Anonymised on request.
›Both NOF teams are on the call, so questions about European and Japanese OEM requirements can be answered in the room.

The kind of question this session is for

"Our customer specifies µ 0.12–0.18 but our torque-tension results scatter across the whole band. Is that the coating, the nut, or the way we are testing?"

"We changed nothing and the same part now needs 15% more torque to reach the same preload. Where do we start looking?"
