In the description of the item it says it fits a 1/2” drive and in one of the questions answered it say the tool fits a 3/8” drive, what size is it?

Hi, My name is Blake and I manage online sales for ATLIN. This tool does, in fact, fit a 1/2" drive. Please disregard replies from anyone stating that it fits 3/8" drive. I am responsible for the manufacture of these tools and I can assure you that they are 1/2" drive.

Will this fit my 03 gti 1.8t

Hi, Yes this should fit your 1.8T

Will this fit the replacement head bolt for a 2001 VW Beetle?

This tool should work for any VW built between 99 and 04. It was incredibly helpful to have. Definitely get it if you're planning on removing the head.

This head bolt tool is made in Taiwan.

Given all the photo reviews of broken tips I was a bit skeptical and scared I even ordered a different kind just in case but it handled the unbolting and torquing procedure perfectly and fit the bolts perfectly as long as you applied pressure. I’m not sure of the longevity but if you need it for one job I would recommend it, I also did a pretest by using an old head bolt and holding it with a vise just to see if it’ll handle 40nm and it did! Would recommend
