Axminster Stacking Turn Studs are a great additional accessory for anyone who already owns either the 250 or 400mm Axminster button jaws. Offered as an alternative to the buttons as a primary gripping device, they give a really positive grip onto square or round section stock. If you rough turn your bowls, then these would also offer an excellent choice for remounting them on the lathe for truing up the spigot prior to re-chucking. The set of eight studs are supplied with two lengths of hex socket screws suitable for using the studs singularly or doubled up for a deeper grip. A hex key is also supplied.
