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.
