Frequently Asked Questions about This Product

This product is an open type product with an opening seam in the middle. It can't be directly measured with calipers. This product needs to be pressed into the H7 seat hole and then inspected with go/no-go gauges. The tolerances shown on the official website are all the tolerances after being pressed in.
