Standard Washer 0.44" ID, 0.88" OD, 0.120" Thickness x 12 pcs

easy to install if not dumb like me, should have been a walk in the park watched vids and got her done.

Very high quality and are on par to th ARP bolts I looking at.

I have not had a chance to install yet as I am still assembling the motor. However I was extremely pleased with the fast shipping and neatness of the packing. Very professional

Looks good, have not used it yet.

Great product , great quality, fast shipping!

Worked as expected

Great shipping and packaging looks like a great product have not been able to install yet

They went in and seem to be working great the only thing I noticed was in the instructions there were a couple of repeated numbers

smaller m8 bolts on exhaust side of head make clearance issues for exhaust manifold gaskets. Also, if block isn't bottom tapped, the studs hit bottom of rocker arm assemblies.

I installed these studs a week ago. So far so good and I don’t expect it to go any other way. They came very well packaged, with clear installation instructions. The head studs are very well manufactured and are a for sure upgrade to do on your diesel engine. I highly recommend buying some Xotic head studs!

Works amazing and they feel nice and strong

I have these head studs in 2 different Cummins motors running better turbos and tunes. We put about 50k miles a year on each truck pulling trailers more often than not and these studs do an amazing job of keeping the head down and the gasket whole. I will be adding them to my next truck at my earliest convenience.

Great packaging!! Easy well illustrated instructions to follow and packing is really clean and organized.

Arrived quickly

6.7L & 5.9L 24V Dodge Cummins Head Stud Kit 1998.5-Present

The price of these are really good! And they torqued up really nice too! Only thing is the steel is from china but still better than a head bolt.

Worked as expected, cleaned out threads .

This thread chasing set is a very high quality item. This set would be for SAE threads with 5 common thread sizes. They are cut very well so your threads will be spot on.

This set offers a good assortment if it has the sizes you need. There are other sets, too, and the individual sizes are available separately. I have some of the sets, and the quality across them has been consistent. I haven't had a chance to try all of the sizes, but so far the threads look to be cleanly cut.

2004+ Chevrolet Gen III IV LS 4.8L 5.3L 5.7L 6.0L 6.2L Small Block Cylinder Head Stud Kit (primary bolts must all have the SAME lengths)

I am rebuilding a 7.3 and will be putting it in an E-350 that I will be pulling a horse trailer with. These appear to be of excellent quality and are packaged with the threads well protected. I did not do destructive testing but these seem up to the intended task. Recommended.

No problem after few passes

Not sure what the difference is between this thread "chaser" and a tap. I ordered a same size tap from another company and they both looked exactly the same. The tap was also much less expensive than this chaser

I've owned and still own all kinds and levels of taps and thread chasers, from one time use garbage to top of the line expensive stuff. These are on par with some of the better stuff I have in terms of metal quality/hardness, and thread precision. I agree with others that for the price they should have case instead of a simple cardboard bubble pack but the quality of the tools is there otherwise.

I was skeptical because this was an unknown brand to me but the quality is on par with the more well known brand I'm used to based on my initial impressions. It's pretty obvious they have pretty strict quality control measures and hopefully they will expand their product line further. It is nice (although not necessary) that they include a socket and allen key.
