Nuts (Lock: Provided)

Nuts (for extruded aluminum extrusions) are fasteners used to attach parts to aluminum extrusions, connect two frames together or the like. Pre- and post-assembly nuts are available. The former is inserted in groove end surfaces of extruded aluminum extrusions before assembly. The latter is inserted in the tops of grooves after assembly. Nuts can be fastened finger-tight in extruded aluminum extrusion grooves by using spring nuts, anti-slip nuts or stoppers. Nuts are made of many different materials and have many different surface treatments, so should be selected to match the application.

Aluminum Frame Nuts vs. Normal Nuts

Aluminum Frame Nuts are specifically designed for use with aluminum extrusion profiles. They are often used in the construction of industrial machinery, automation equipment, and various other structures.

Normal Nuts are typically made of steel or other metals and are used in a wide range of applications. They are strong, durable, and can withstand high loads.

Feature	Normal Nut	Aluminum Frame Nut
Material	Steel or other metals	Aluminum alloy
Design	Standard nut design	Specialized design for aluminum profiles
Application	General-purpose fastening	Securing components to aluminum profiles
Strength	High strength, suitable for heavy-duty applications	Sufficient strength for most applications involving aluminum profiles
Weight	Heavier than aluminum frame nuts	Lighter weight, reducing overall weight of the structure

In essence, the primary difference between normal nuts and aluminum frame nuts lies in their specific design and application. Normal nuts are versatile and can be used in various applications, while aluminum frame nuts are tailored for use with aluminum profiles, providing a secure and lightweight solution.

Question: what's the difference between bolt and screw?

Answer: The screw looks like a bolt, however, it has a shaped tip. The thread of the screw mate with the material. It is turned through to hold the screw in materials such as wood and plastic without using a nut
On the other hand, the bolt is not designed for self-tapping material, so that requires a nut to hold the bolt and object together

Question: Which is nut and which is bolt?

Answer: The easy way to categorized between nut and bolt is
– Nuts have a screw hole,which has thread inside for example Hex nuts, Flanged nuts, Square nut and etc
– Bolts have an external male thread, which always use with nuts or screw hole for example Hex bolt, T-Bolt , Eye bolt etc.

Question: How many nut types are there?

Answer: Nuts have varieties of types, sizes and materials for example,
Nut for aluminum profile can categorized by 2 types
1. Post-Assembly: Mountable from slots after assembly such as Free nut, Special T-nuts , Leaf spring T-nut, Ball spring T-nut, T- bolt and so on
2. Pre-Assembly: Insert from the slot ends before assembly such as T-nut, Long T-nut, T-nut with stopper , T-nut with set screw etc.

Question: Does a screw need a nut?

Answer: When you use screws don't need to use nuts, because the screw has threads spiraling along the length, which can drill and stick to the material without using a nut. On the other hand, bolts need to use with nuts to hold two or more objects together.

Question: How do you fasten nuts properly?

Answer: 1. Before using a nut and a bolt need to check both of them have the same size of threads and pitch, for example, bolt size M8x1.5 and nut size M8x1.5 is OK
2. Use hands for tight a bolt and a nut mate together
3. Use a wrench or hex socket wrench to fasten it until tight
