10 Things to Know About Automotive Fasteners

Reprint from China Fastener World Magazine, Vol. 45

During my first twenty five years in the fastener industry I worked for a fastener manufacturer that focused primarily on automotive fasteners. Several years into my tenure I had the opportunity to work on a project outside of the automotive industry, with a large computer and peripherals manufacturer. After many months of project work it was obvious that the project was dead-on-arrival. This was an uncustomary loss and as I reflected on the reasons for this, the one that stood out above all the others was that we were simply not equipped to support the needs unique to this industry segment. We were very capable of providing the necessary application engineering and had the manufacturing capabilities, but we were too ingrained in our own paradigms and lacked important industry specific knowledge so that we failed to execute properly to meet the customer ́s needs.

Trends in the Automotive Industry and How They Affect Fastener Suppliers

Perhaps with the exception of the consumer electronics industry, no other high profile industry seems to embody and embrace change as much as the automotive industry. In fact, new car buyers have come to rely on the fact that the new model year will bring exciting new changes and innovations. And although it may take several years to launch a specific new model into the market, the automotive OEMS stagger releases in such a way that they are consistently releasing new models and complete model refreshers every year. As such, suppliers to automotive OEMs and their vast Tier network must be always vigilant and striving to keep up-to-date with industry advancements.

Automotive Cold Headed Components

The other day I received an email from an individual at one of the companies that I work with asking me if I was aware of any industry standards for wheel studs. I had to think about this for a bit and ultimately replied that I was unaware of any formal, industrywide document pertaining to this product. I went on to explain that in my experience, although many wheel stud designs were likely similar from one automotive OEM or supplier to another, that each OEM or supplier had their own special “spin” on part design and functionality. The result is a wide body of ‘Tribal Knowledge” on such parts but a dearth of formal, industrywide standards or know-how.

5 Things About Miniature Screws

Humans seem to be fascinated with anything outside the norm. Everybody seems to marvel at things of immense size, like those big tractor tires that a grown man can fit inside, the world’s largest ball of twine, and the Great Wall of China. Equally fabulous, though, are things that are very small. In fact, the Guinness Book of World Records seems to have an endless number of record small things.

Screws and fasteners, like many other items, also come in very small sizes. In fact, there are threaded fasteners that are so small it is difficult to make out their features with the naked eye. Of course, it makes sense that there would be an abundant variety of miniature fasteners, since small assemblies must be held together just like their larger counterparts. Therefore, although they come in tiny packages, they are expected to perform in a big fashion.

Heat Treating Automotive Fasteners

About twenty years ago I was working with an automotive foundation brake supplier when catastrophe struck. One of this company’s calipers utilized a Collette Style Pin brake caliper design. These calipers operate by sliding along a two piece pin system. There is a Collette Pin with a tapped hole in the head and a Mounting Bolt. The Mounting Bolt connects the face of the Collette Pin to the back side of the Piston Body Flange, providing unfettered access for the caliper bracket to slide along these pins when the brake is functioning.

Automotive Platings and Coatings

When I started in the fastener industry thirty years ago, our automotive customers were significantly divided in how they approached the platings and coatings used on fasteners. The spectrum ranged on one end from OEMs that had only a handful of choices to the other end of the spectrum where it seemed there was an option for every engineer that had been convinced by a plating chemical supplier that they had the best mousetrap. In the intervening years this has mostly changed, so that today, even though each automotive OEM still has their own set of standards and preferred finishes, the selection has tightened up considerably so that all the OEMS are now doing relatively similar things.

To understand how we have arrived at the place we are today, one has to understand a number of trends and occurrences that have either helped or forced the industry to go in a particular direction. Most of the rest of this article will focus on these discrete events to assist us in understanding the landscape today.

Although every model automobile is different, the average automobile contains several thousand fasteners. The total number is comprised of screws, bolts, nuts, washers, clips, and specialized, engineered specials and variants of all the following. The assortment and variety of different fasteners is impressive by any standard. One would think that because of this variety gaining entry into the automotive fastener market would be an easy accomplishment. This assumption, however, would be incorrect. In fact, the reality is very different; becoming a supplier to automotive customers is generally an onerous task and a monumental accomplishment.

To understand why it is so difficult one has to understand some of the differences between the automotive fastener market and all others. At the forefront is an understanding of fastener “standards”.
