BMW S55 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 / mm² 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: P102081410
  • Kit content: 14 stud bolt (M11) / 14 nut (M11) / 14 washers / assembly lube/ assembly instructions
  • Tensile strength: PS 18.8 steel / 1850+ N/mm² (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 / mm².
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 or optional with a burnished 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 / mm².

Sketchy
I bought this 2 pack and activated it for use in a remote device, not a cell phone. Activating it on the phone with T-Moble is easy enough. You will need to tell them the devices IMEI number, the zip code where service will be used, and the SIM Card Number printed on the SIM card. They charge a $5 activation fee along with the first month's payment for whatever data plan you choose. The minimum you could choose is a 2GB/month plan for $10/month with automatic activation. (I wish I had read the details on the product more closely. I made the mistake of seeing some value in "pre-paid". There is NOTHING PRE-PAID about this card. Plus the customer service seems a bit sketchy. On my first call I didn't have the IMEI device number. When I explained that I'd have to call back, the tech tried several different ways to press me for the SIM card number and other details to speed up the process when I called in again. That seemed odd since he wasn't able to create an account for me in the system without all of the information and the $5 activation fee. So, despite being a catch-22 he kept trying to get the SIM card number.

No se pudo activar, pero fue culpa de servicio al cliente.
Compré la tarjeta porque muchas compañías no querían activar mi celular chino, un Xiaomi Note 12 Pro+ 5g, y cuando lo puse dentro de mi celular pude llamar perfectamente al servicio de activación donde me pusieron mil excusas sobre que mi celular chino no funcionaba y no iba a funcionar y me desactivaron mi tarjeta SIM de Amazon, fui físicamente a una sucursal y me atendieron mucho mejor y me activaron una SIM literalmente igual a ésta, y ahora estoy con internet perfectamente funcional con un plan prepago como la de esta tarjeta. Bien producto, terrible servicio al cliente.
