    Low-Profile Knurled-Head Thumb Nuts

    Twist these thumb nuts into spaces without a lot of clearance. They have a short, slip-resistant head, so you can grip them easily and make controlled adjustments in cramped spots. You can also use them as jam nuts by threading them against another nut to hold it in place.
