VAG 1.8T 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: P101021010
Kit content: 10 stud bolt (M10) / 10 nut (M10) / 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�.

Title says it all: ESSENTIAL!
Format: Paperback
This is a FANTASTIC book! The information may seem overwhelming at first, but it is easy to understand.
As some reviewers said, it does not spend much time on hand lettering (I assume this is due to the industry going more digital as time goes on). Those who want more information on hand lettering may have to seek help elsewhere. It is mentioned VERY briefly in the beginning, I believe.
It includes: step by step instructions on creating speech bubbles, tips on font creations, sentence formatting, page borders, splash/double splash page construction, creating templates that save you time in the long run, making logos, sound effects and much more.
This book is a great launching point for anyone looking to start their lettering career or even for anyone that wants to gain an appreciation for an intergral and often overlooked part of Comic books!

One of the Best "Making Comics" Books Out There

Honestly, one of the best books on making comics that I've read. So well done, insightful, well-organized, and easily referential. If you're looking for the basic principles of lettering, look no further than this.
