Heavy Hex Finish Nuts are Stronger and Thicker than Regular Finish Hex Nuts.
A Heavy Hex Nut is used on a Propeller Shaft and are paired with a Heavy Hex Jam Nut. This Combination is Used to Secure the Propeller on The Shaft. This Hex and Jam Combination is the Staple of the Marine Propulsion Industry.
Heavy Thick Nuts are Also Used on Hex Bolts and Carriage Bolts Where a Heavier Finish Hex Nut is needed for Strength.
