## Description

Review: Fits the three 8mm rods that I needed them for. Threaded screw fits properly and snugly. I had a bit of a laugh in that the resealable package ("ziploc" style) was heat-sealed shut BELOW the reseal, so after breaking the heat-seal (cutting it off) you couldn't reseal it anymore.
Review: Great little shaft collars with flanges. Dimensions were accurate and surface finish is good. They worked so well I got a second set.
