Hex Spindle Nuts.

Made from quality alloy steel and heat treated for strength, these spindle nuts feature a flange face precisely perpendicular to the thread for maximum clamping surface. The milled hex provides solid wrench engagement for safety. Left-hand threads are easily identified with LH designations stamped on the face. Nuts have black oxide finish.
