Quality! The packaging was excellent

5/5

Great for headers that don't have enough room for a socket. It's also a lot less work than making your own custom wrench. br>br>However, the tool that comes with the bolts is a complete waste of money. A 3/16 Allen L handle and a 3/16 Allen socket for a ratchet are both highly recommended.

I've never used better header bolts! On my 1967 Camaro, I used the locking header bolts to secure a set of long tube headers

5/5

I've never had a better experience with a product. Excellent value for money and prompt delivery.

The tool had malfunctioned

4/5

I like the product, but the Allen wrench broke off in the head of a bolt; a higher-quality tool would be preferable. However, I am pleased with the finished product.

The vibrations were audible

3/5

Like the less expensive Oreillys bolt kits, the bolts vibrated out. Headman long tube headers had been installed on a 383 stroker. I used stage 8 locking header bolts, which are fantastic. I'm sure these work for some people, but they don't work for my application or setup.
