XXX Pro-Series 18.8 Cylinder Head Stud SetReplacing 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: P101102010
Kit content: 20 stud bolt / 20 nut / 20 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�.

Waterproof perfect as travel fountain pen case
Awesome very small size waterproof bag. Purchased to use as a travel case for my fountain pens and ink (just in case). Although I have never had an ink accident, I wanted something compact enough to use in a small cross body bag without wasting space for the sake of an extra measure of assurance I wouldn't end up wearing my ink.
NOTE, I do not use the disposable ink cartridges only adapters or dropper fill. So if I were to experience an ink mishap it would be more than just a tiny amount of permanent ink.
The bag seems to be very well made. It is exactly as described, the only thing that may not be obvious is that the material is quite robust and there is no real give. So it works perfectly as a pencase and for a passport or smaller notebook. I would note recommend using it for something thick or round, like an apple or a larger size bottle of ink. However for a syringe full of ink along with half a dozen fountain pens it's superb!
Will definitely buy again when need arises.
This would also make for a great safe case for a smaller phone. However current flagship phones will not fit through the limiting zipper length.
A future improvement of having the zipper go just around the corner to allow full length access would be an awesome improvement which would then be perfect for a newer model cell phone.

Very Handy for Writing and EDC!
It does exactly what I need it to! It fits well on my A5 notebook and has just enough room in the pouch for a small knife, a lighter, a small flashlight, and some pens! It's a perfect edc carry for anyone who likes to have a small notebook on hand! Also the quality is really amazing and I have no doubts that this handy little pouch will last a long time.

Moderately Effective, Not Worth The Price
Doesn't hold much. The hand strap on the back as it's impossible to get it to a point where it may be tight around a large, adult hand. Unsure how well the elastic loops will safely retain pens over time.
