Sometimes tight quarters restrict you from steadying a screw with one hand while you turn a screwdriver with your other hand.

Drop a small dab of hot- melt glue onto the head of the fastener, and attach the screwdriver or ratchet with the glue. When you finish driving the fastener, the tool will release easily. A little scraping removes any residual adhesive.
