BMW M20 Engine Pro-Series 18.8 Cylinder Head Stud Set

Replacing the original cylinder head screws with high-strength Pro-Series 18.8 studs.
This is necessary when making large increases in performance, as the original cylinder head screws elongate during operation and the cylinder head can lift off.
The Pro-Series 18.8 stud bolts with a tensile strength of 1850 N / mm� provide a solution to this.
In addition, these stud bolts do not have to be replaced after dismantling, but can be reused.

Technical details:
Manufacturer part number: P102011410
Kit content: 14 stud bolt (M10) / 14 nut (M10) / 14 washers / assembly paste / assembly instructions
Tensile strength: PS 18.8 steel / 1850+ N/mm� (270.000+PSI)


The Pro-Series 18.8 sets are high-strength stud bolts manufactured in Germany.
A special steel is used which, after tempering, has a tensile strength of 1850 + N / mm�.
All threads are formed and not cut as usual. The so-called rolling of threads can increase the strength of the tooth flanks by around 30%. All Pro-Series products are supplied with a nickel coating protecting against corrosion in the long term, even under the toughest conditions. Pro-Series stud bolts have a hexagon socket drive on the head side for screwing in the stud bolts. Due to a cone on the engine block side of the bolt, these are not supported on the thread flanks when the nuts are tightened, but in the bore of the thread in the engine block. This support protects the threads when racing engines are frequently rebuilt.
Pro-Series advantage over other manufacturers is the nuts and washers included in the set, these also have a tensile strength of 1850 N / mm�.

Pretty hard to clean
Color: Cinamutt Roll - Large, Size: Large
We've had this for about a week now. I have 2 dogs, one small one about 55lb. I bought this for my big girl, but lil man is determined to get the best of this toy. Usually they don't both go after the same toys, so this is interesting. The trouble is, neither one of them can get all the treats out if something makes it all the way down into the crevice. It's surprisingly deep. The up side is that they'll try for quite a while before giving up. The down side is even if you put it in the top rack of the dishwasher, something stuck deep in there isn't going anywhere until you dig it out yourself. I tried a plastic knife but it broke the second time I used it in there. I wound up using the metal handle of a reusable straw cleaner. Which then I had to wash that, too. Then it needs to dry overnight before it can be used again. All in all, the dogs like it fine, it's gross to scrape out and wash, takes longer than most toys to dry, and I have the feeling that will eventually cause me to pass it to someone else's dog long before my two have gotten tired of it. At this point I'm pulling out of the toy rotation for a week or two because I'm not ready to clean it a third time.

Hyena Proof
Color: Acorn - Large, Size: Large
I have an American Bulldog that would chew a brick if he didn’t have an alternative lying around. They won’t last forever (nothing does) but we’ve had two of these over the course of a year and for him that is nothing short of a miracle. And that is daily chewing like it’s his job. I highly recommend the Acornucopia for aggressive chewers with jaws like hyenas…so it’s probably great for your dog too.

This is an awesome product and affordably priced! I'll buy more in the future!
Color: Comet - Small, Size: Small
This is a great ball for my dog Polly! It doesn't stink or have any weird oils on the ball. It is definitely durable. It has a nice chirping sound and it's great exercise for my dog's jaws. It's not too bouncy and it's the perfect weight that she feels satisfied having in her mouth and when she catches it in mid-air. It's not too heavy that I have to worry about it knocking her teeth out. I almost cancelled the order after I found out the size of the ball, I thought it was a larger ball that Bark makes. It turns out it is larger than a tennis ball which is what I wanted. Someone gave us a black, knobby, ball that is 12.5 inches in diameter and she absolutely loves it, it's her favorite ball. It's the perfect size for her American Pit Bull mouth! I cannot find this product anywhere or a comparable alternative that's the same size. If you know where I can purchase another ball that I've described @ 12.5 in. diameter, please let me know! I'll likely buy this ball that was just delivered, today, in the future, if it's not discontinued! It's a great deal for only $14.99!! Thanks from a happy satisfied customer, V.B.

Only ball he has not destroyed in minutes!!! So good that I purchased a second one for travel. It keeps him busy and tires him out because he cannot break it!😆
