KEEP IT TOGETHER
CHROMIUM H11 TOOL-STEEL
It’s not rocket science, but it’s close. Our chromium-based H11 tool steel alloy is known for its use in aerospace industry applications like helicopter blades and landing gear. H11 is widely used for its crack-resistant properties to prevent thermal fatigue or thermal shock. This alloy’s low-carbon content gives it strength with minimal distortion when tooling. If it’s good enough to land a plane, it’s the right choice for your high-performance engine.
Unlike stock stretch bolts, HoldStrong head studs do not stretch to torque and are reusable.
IT'S ALL IN THE THREADS
iE head studs are manufactured using a rolled method in a pure oil solution. The alloy material is shaped rather than removed (cut) which creates a compressive force that strengthens the thread and eliminates imperfections that could cause stress cracks. Rolled threads are built for strength and extreme fatigue resistance.
iE ROLLED THREADS
- Precise surface finish
Roll forming the threads in a contained die produces an incredibly smooth thread surface that greatly reduces the chances of stress cracks. - Compressed material
Instead of removing material, the alloy is compressed to form the threads which greatly increases strength and fatigue resistance. To maintain the structural integrity of the material during this process, heat caused by friction is reduced using a cooling oil. - Accurate thread profile
The precise thread forming also produces a very consistent thread profile and dimensional accuracy, which delivers greater thread engagement and improves the overall performance of the fastener.
TRADITIONAL CUT THREADS
- Surface imperfections
The thread surface of a machined (cut) fastener is at risk to surface chatter and burrs. These small imperfections can cause stress concentrations and thread failure. - Removed material
Forming the threads by cutting material away removes and weakens the alloy. Less material means lower strength and fatigue resistance. - Unstable thread profile
While faster and cheaper to produce, cut threads can not maintain a truly consistent thread profile, making them less than ideal for critical clamping loads required for performance builds.
NOT ALL THREADS ARE EQUAL
The sharp edges and corners of standard cut thread can cause stress points that lead to bolt failure. To prevent this, iE head studs have been engineered with J-threads. This higher quality thread profile has a curved minor-diameter structure to reduce stress points and prevent breakage from vibration. J-threads also provide a more accurate sizing for an exact dimensional fit.
WHAT IS HEAD LIFT?
The VW and Audi MQB Gen 3 EA888 engine is an incredibly popular platform for power hungry enthusiasts. With many builders pushing into bigger turbos, race fuels, and big boost it's not uncommon to see these engines pushing 500+HP. These massive gains result in higher cylinder pressures that put a lot of stress on the factory head bolts. When the factory bolts hit their limit, they stretch and cause head lift. This breaks the cylinder head gasket seal which results in compression loss, oil/coolant contamination, loss of power, and in extreme conditions; catastrophic engine failure.

Dries clear, moisturizing, silky, great value
Size: 5 Fl Oz (Pack of 1), Style: SPF 50
I have fair to light combination skin. I use this on my body, but not my face. It goes on very thick and white, but sinks into the skin lightning fast (within just a few seconds), and it becomes completely invisible. It leaves my skin moisturized and looking and feeling silky. Best body sunscreen I've ever tried. And I love that it is water resistant! I find it too heavy and moisturizing to use on my face, but people with dry skin would probably love it for the face, too. I imagine it would be fantastic for them under makeup. The price per ounce is very reasonable, making it a great value.

Reliable Sun Protection for Active Days!
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Coppertone SPORT SPF 50 is my go-to sunscreen for outdoor activities. It’s lightweight, non-greasy, and stays on even when I’m sweating or swimming. The broad-spectrum formula protects against both UVA and UVB rays, giving me peace of mind during long hours in the sun.
The 3 fl oz size is perfect for carrying in a gym bag, backpack, or beach tote, making it easy to reapply throughout the day. It absorbs quickly and doesn’t leave a sticky residue, which is great for sports or active adventures.
Highly recommend for anyone who wants effective, durable sun protection without sacrificing comfort or mobility!

IT does protect from the sun.
Size: 5 Fl Oz (Pack of 1), Style: SPF 50
It protects from the sun without a doubt and lasts well. The downsides are that it leaves a greasy and "white" residue that no matter how much you rub it in.....it stays there. I use it when I am working outside and not planning on going anywhere anytime soon.
