Huracan 5.2 Engine 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: P110022410
Kit content: 24 stud bolt (M10) / 24 nut (M10) / 24 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�.

Have these connected to OFC 0 gauge wire running nearly 10K watts they handle it perfect!
It’s been months since I bought these and I run one coming off my main battery and then another on my auxiliary battery. I’ve got a huge alternator and running nearly 10K on my set up before I even started to think about what Speakers size or anything like that I made sure that the power and wiring is gonna be top notch. I see almost no voltage drops have not had a problem with these whatsoever.

Good quality, good price.
Review of RECOIL ZAFH2-200 2 Pack in-line ANL Fuse-Holders
I recently purchased the RECOIL ZAFH2-200 2 Pack in-line ANL Fuse-Holders, and I must say, I am thoroughly impressed with the quality and performance for such an affordable price. At just $12 for two holders, it’s hard to argue against their value.
First off, the build quality is commendable. The materials used feel robust and sturdy, which gives me confidence that they will withstand the demands of my automotive and audio setup. The versatility of being able to accommodate 0, 2, and 4 gauge inputs and outputs, enhanced with reducers, makes these fuse holders suitable for a variety of installations.
Installation was straightforward, and the holders fit snugly with no issues. The included 200A ANL fuses are a definite bonus, offering adequate protection for my system. Knowing that I have two holders on hand allows me to set up multiple devices or systems without needing to rush back to the store for more.
What impressed me most, however, is the performance. I’ve tested these fuse holders with a range of power demands, and they have held up beautifully, showing no signs of overheating or performance loss. The current flow remains consistent, and I appreciate the peace of mind that comes with reliable fuse protection.
After positive experiences with my first purchase, I’ve already taken the liberty to buy more of these holders. I highly recommend the RECOIL ZAFH2-200 for anyone looking for budget-friendly yet reliable fuse-holding solutions. They offer excellent value for money, and you can’t beat the convenience of having a dual pack.
Overall, if you’re in the market for ANL fuse holders, give these a try—you won’t be disappointed!

Good bang for your buck, great quality.
Works great. Most of it is metal and works as a heat sink. Came with two fuses and the adapters for smaller or larger Guage wires. Fit very well and easily for our choice of installation and was a great price.
