FEATURES: Metric version of our popular DG bushes, designed for cast-in-place or potted installation. Diamond-knurled OD provides excellent holding strength against both rotational and axial forces. Since the bush's OD is not ground, the ID must be accurately located during casting or potting to ensure accuracy in the finished tool.
