A screw lock permanently mounted on a sliding panel includes a finger engageable means mounted on a lock bolt threaded at its distal end. A spring biases the bolt to an unlatched position. A keeper member formed with a threaded opening is mounted on a fixed panel for registration with the threaded lock bolt in the closed panel position. A flange on the sliding panel interlocks with a flange on the fixed panel in the closed position.
