    Hex Finish Nuts Black Oxide 18-8 Stainless Steel

    Hex Nuts in Black Oxide Coated Stainless Steel

    Standard Hexagonal Nuts For General Applications

    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. 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.

    Stainless Steel

    18-8 or 304 grades of Stainless steel are suitable for many general purpose applications, especially freshwater and non-salt water wet environments. Corrosion-resistant and durable, 18-8 stainless steel is equivalent to the A2 grade of stainless steel.

    Black Oxide Coating

    18-8 stainless steel hex nuts are available in a black oxide coating, which adds mild corrosion and abrasion resistance, but is mostly used for the color.


    FAQs

    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 black oxide used for?

    Black oxide is used to add mild corrosion resistance, abrasion resistance, for appearances, and to minimize light reflection.

    What does 18-8 mean?

    In regards to stainless steel, 18-8 (sometimes written as 18/8) is the composition of chromium (18%) and nickel (8%) in the stainless steel alloy. 18-8 also refers to the 300 series of stainless steel grades, including 302, 303, 304, & 316. Though you'll often find it used interchangeably with the 304 grade because it's the best known stainless grade in the series.
