Received today in a secure box. The first inspection shows good thread quality inside and out. However, there are 2 details that need to be provided: 1) This is 6-spline, not 7-spline. I sent it back and looked at the description of the goods, it doesn't say anything and it can't be seen in the pictures. So if you're looking for hard-to-remove (stealing) spline nuts, look elsewhere. The funny thing is, I think some of their other stuff is marked with 7 splines, but I'm too tired to confirm my memory 2) To say "Comes in our premium branded packaging." is a laugh a minute . Here's the reality: packed in a plastic bag, placed in a semi-tight box with your company name printed on cardboard, and then stuffed into a tight-fitting USPS envelope. They arrived safely, but "signature premium packaging"? Otherwise they seem to be ok. I'll try installing them on my aftermarket wheels this weekend, see what happens and update this review later.
