The pawls are not fully engaged in the hub - you need to retract them either with a pointy thing or by wrapping thin wire around them temporarily, removing it as the freehub drops fully home/flush. It does not 'screw into' the hub, it drops in (save for the obstruction of expanded pawls) and is then retained by the axle/nuts.
