Shaft-mounted rockers rely on their studs to hold alignment under valve spring load, and the factory hardware is a known weak point once spring pressures go up. These studs are threaded 3/8 in. coarse at both ends and run 3.62 in. long, giving a firmer clamp on the shaft so it stops walking and wearing the mounting pads.
