Metric Hex Nuts in Zinc Plated Class 8 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.
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 threaded rod. Zinc plated threaded rod is ideal for indoor use where it won't be constantly exposed to harsh elements.
Steel classes in this selection of hex nuts have a zinc plating on them. Class 8 steels are all zinc plated. Class 8 is the metric equivalent of grade 5 steel in terms of strength and other properties. A full breakdown of available grades and classes of steel is below.
- SAE Grade 2 - Low Strength Carbon Steel
- SAE Grade 5 - Medium Strength Carbon Steel
- SAE Grade 8 - High Strength, Thru-Hardened Steel
- Metric Class 8 - Comparable to Grade 5
- Metric Class 10 - Comparable to Grade 8
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.
What is a class 8 nut?
Class 8 nuts are metrics nuts with a steel grade equivalent to the SAE grade 5 classification. These are medium-strength steels used in many general-purpose applications.
