This is a Strandberg-compatible bridge part. The screw threads are made of stainless steel and are helicoiled, making them less likely to strip like the original NX parts. The material is aluminum, and the weight is almost the same as the original. The second photo shows the part installed, so please refer to it. The item for sale is only the one in the first photo. Please note that other parts are not included. It will be shipped via Yu-Packet Post.
