A forged, mill liner bolt (100) has a head (114), a shank (112), tapered load-bearing surfaces (116) and lateral projections (120) defining an undercut surface (117), and a sealing member (118) abutting the undercut surface. A plurality of plastically deformable projections (122) extend from the tapered load-bearing surfaces (116) for spreading a load applied to the bolt. Sealing member (118) provides a partially-elastic joint to maintain clamp loading. Sealing member (118) provides an interior seal within a bore in a mill liner to prevent leaking of and racing by mill slurry liquids.
