The Ultimate Guide To Hexagon Nuts And Locking Screws

Hexagon nuts are used for bolt locking and are a simple and effective safety device to prevent the loosening of a joint. They are available in a range of materials, including steel, stainless steel, carbon steel, and aluminium. Hexagon nuts can be purchased in different quantities, from packs of 10 to packs of 100, and in a variety of sizes, including M3, M4, M5, M6, M8, M10, M12, and M16. They are also available in different standards, such as DIN 934, DIN 985, and ANSI B18.6.3. Hexagon nuts are used in various applications, including military, industrial, and scientific.

Self-locking Hexagon Nuts

The metal section of a nylon-locking nut is typically made from A2 stainless steel, also known as 18-8 or 304 stainless steel. This type of steel is known for its durability and corrosion resistance. The nylon insert is located in a tapered section at the back of the nut. When the nut is installed on a bolt or threaded stud, the nylon insert wraps around the threads, locking the nut in place. This makes nylon-locking nuts ideal for applications where vibration is present, as they are unaffected by it.

To use a nylon-locking nut, first examine the nylon insert to ensure it is not damaged. Thread the nut onto the bolt or threaded stud by hand until it can no longer turn. This is when the nylon insert contacts the top thread of the fastener. Place the appropriate socket on a 3/8-inch drive ratchet and slide it onto the nylon-locking nut. Turn the ratchet handle clockwise to tighten the nut, and continue until it seats tightly against the surface of the material being secured. Finally, inspect the nylon insert to ensure it is intact.

Nylon-locking nuts are available in both metric and imperial sizes. Metric sizes range from M2 to M20, while imperial sizes range from No. 2 up to 1 inch. They are commonly used across a wide range of industries, including appliances, computers, furniture, medical equipment, vehicles, sheet metal, and aircraft.

Hex Nuts for Bolts

Hex nuts are used for bolt locking and create a simple and effective safety device against the loosening of a joint with standard bolts. They do not require other fasteners or machine elements like split pins or lock washers. An additional machining of the screw shank, the thread end, or bolt can be omitted. Hex nuts are available in different grades, with varying tensile strength and radial lines on the head. For example, Grade 5 Hex Cap Screws have 3 radial lines on the head and can withstand a minimum of 120,000 PSI tensile strength, while Grade 8 Hex Cap Screws have 6 radial lines and can withstand a minimum of 150,000 PSI.

Hex nuts come in various materials, including stainless steel, brass, and zinc-plated or galvanized steel. Stainless steel hex nuts offer excellent corrosion resistance and durability, making them suitable for applications requiring precise tolerances. Brass hex nuts also offer good corrosion resistance and are a good choice for low-friction applications due to their excellent conductivity. Zinc-plated and galvanized hex nuts provide protection against corrosion and are commonly used in fastener applications.

Hex nuts are available in a range of sizes and can be purchased individually or in packs. They are commonly used in industrial, scientific, automotive, and home improvement applications. When purchasing hex nuts, it is important to consider the appropriate size and grade for your specific application.

Additionally, hex nuts can be found as part of kits or assortments, which include various sizes and types of nuts, bolts, washers, and other fasteners. These kits provide convenience and ensure that you have a variety of fasteners on hand for different projects.

Hex Nuts with Metric Right-Hand Thread

Hex nuts are used for bolt locking and create a simple safety device to prevent the loosening of a joint. They can be used with all standard bolts and do not require additional fasteners such as split pins or lock washers.

Hex nuts come in a variety of sizes and materials. Metric hex nuts are available in sizes ranging from M2 to M12. They can be made from stainless steel, brass, or steel with a zinc-plated finish.

When choosing a hex nut, it is important to consider the thread direction. Right-hand thread hex nuts are designed to be tightened in a clockwise direction and loosened by turning counter-clockwise. This is the most common thread direction and is typically used when standard right-hand threads are compatible with the application.

Another option is the Hillman hex nut, available in a pack of 6 from Amazon. This product has a brass finish and a size of 10-32.

When selecting hex nuts, it is important to consider the specific requirements of your project, including the size, material, and thread direction needed.

Hex Nuts with Fine Thread

Hex nuts are used for bolt locking and create an effective and simple safety device against the loosening of a joint with all standard bolts. This does not require other fasteners or machine elements. An additional machining of the screw shank, the thread end or bolt can be omitted.

Hex nuts are available in a variety of sizes and materials. For example, The Hillman Group offers a 5-pack of 5/8-18-inch jam nuts, while Blue-Jay Fasteners offer a 100-pack of 1/2-20 fine hex nuts made of zinc and dichromate.

Amazon offers a range of hex nuts in various pack sizes, thread sizes, and materials. For instance, there are packs of 10, 25, 50, and 100 hex nuts available, with thread sizes ranging from 1/2-20 to 5/8-18. These nuts are made from materials such as plain stainless steel, black oxide steel, and zinc-plated steel.

The Home Depot also offers fine hex nuts, although it is currently out of stock.

Hex Nuts with Coarse Thread

Hex nuts are used for bolt locking and create a simple safety device against the loosening of a joint with all standard bolts. They are the most commonly used nut and are often found in deck and fence building. Hex nuts are compatible with bolts and washers of the same finish.

These nuts are ideal for a wide range of projects, including both indoor and outdoor use, making them essential for construction, automotive, and DIY projects. They are available in various materials, including stainless steel, zinc-plated steel, and galvanized steel.
