Heavy Hex Nuts in Zinc Plated Steel
Thicker and Stronger Hex Finish Nuts
Heavy hex finish nuts, also known as heavy hex finished nuts, and heavy hex nuts, are used for many fastening applications. Heavy hex finish nuts are often used with hex cap screws and carriage bolts when a heavier, stronger, and thicker nut is needed. This is usually done for strength or a thicker finished look.
The hexagonal shape makes these nuts easy to grasp with a wrench or pliers. They are installed on the opposite side of the materials being fastened. With the bolt head or machine screw head on the other side, they compress the materials together for a secure fit.
Zinc Plated Steel
Zinc is by far the most common and economical type of plating for fasteners. The zinc plating adds a protective "sacrificial" top layer against corrosion while also adding a shiny finish to the fastener. Zinc plating is ideal for indoor use, where it won't be constantly exposed to harsh elements.

FAQs
What is a heavy hex nut?
Heavy hex nuts are larger and thicker versions of standard hex nuts. They are often used to complement larger, heavier, and high strength bolts to further improve the connection's strength.
How do you size a hex nut?
Hex nuts are sized by the diameter of the internally threaded hole and the thread pitch of the hole's threading. For example, a 1/4"-20 hex nut has a 1/4 inch diameter hole with 20 threads per inch of internal threading. When selecting a nut to match a bolt, be sure they have the same diameter and thread pitch.
What are hex nuts?
Hex nuts are hexagonal blocks of material, typically metal, with a hole punched through that is threaded. Hex nuts, or hex finish nuts, are the most common type of finish nut used. The hexagonal shape makes these nuts easy to grasp with a wrench or pliers. These nuts are often used with screws and bolts when mechanically joining materials together.
What is a hex nut used for?
Hex nuts are used alongside machine threaded fasteners to complete a secure assembly. The head of the screw or bolt clamps down on the material while the nut clamps down on the opposite side. This effectively "sandwiches" the assembly securely together.
How does a hex nut work?
Hex nuts work jointly with machine threaded fasteners such as bolts, anchors, and machine screws to effectively clamp down on both sides of the fastened material. The bolt and nut threading causes friction against each other, allowing a secure fit for general applications. A lock nut is used instead if the application would be subject to high amounts of vibration.
What is zinc plated steel?
Zinc plated steel is steel that goes through adding a layer or coating of zinc to protect the steel from corrosion. The added layer of zinc sacrifices itself to keep the steel from rusting, even if the plating is damaged.
