    Narrow-Profile Hex Nuts

    When you have limited space for tightening with a wrench, use these nuts. Since they’re about 20% narrower, they fit in tight spots where standard-profile nuts won't fit. Also known as small-pattern hex nuts.

    Left-Hand-Thread Thin-Profile Hex Nuts

    These nuts tighten when turned to the left. Use them with left-hand rods and screws to prevent counterclockwise-moving parts from loosening. About half the height of standard-profile nuts, these fit in spaces with low clearance. You can also use them as jam nuts by threading them against another hex nut to hold it in place.
