Aluminum Knurled Thumb Screw

Type: Aluminum screws, knurled thumb screw, aluminum bolts

Material: Aluminum

Finish: Natural


Standard: Inches, Metric


An aluminum knurled thumb screw is made of aluminum material. This is type of aluminum fasteners which inculde aluminum screws,aluminum bolts,aluminum nuts.The specific gravity of aluminum material is only one-third of that of steel material. It is a metal material with light weight and excellent electrical conductivity, heat transfer, and ductility. In addition, aluminum alloy can obtain the same strength as steel material. Therefore, aluminum materials can be used on the premise that both high lightness and light weight are required. Although the parts of aluminum screws are far from being very popular, in related industries such as airlines and medical equipment, aluminum alloy screws are widely used. It has unique properties and its uses are becoming more and more common. Aluminum screw parts are divided into the following three types: 1100 aluminum coins, aluminum-magnesium-aluminum alloys, and aluminum-magnesium-zinc alloys

  • Performance characteristics and application of 1100 aluminum wire.1100 aluminum material, the aluminum content (mass concentration) is 99.00%), and cannot be strengthened by heat treatment. It has strong heat resistance, electrical conductivity and thermal conductivity, its density is small, and its plastic deformation is relatively good.
  • Aluminum-magnesium alloy is the better aluminum alloy among the three in corrosion resistance, and its production and processing performance is very good. Although the compressive strength is at a medium level, the stability of structural mechanical properties is good, so it is the most widely used aluminum alloy. , The representative models are A5005 and A5052.
  • Aluminum-magnesium-zinc alloy is an aluminum alloy with the highest strength among the three. Among them, A7075 (super carbon tool steel) is used in aerospace engineering and other industries. However, the corrosion resistance of this series of aluminum alloys Worse than aluminum magnesium aluminum alloy.

Each material has different performance characteristics. Let us carefully analyze whether the use of aluminum screws is necessary for light weight when selecting non-standard special-shaped screws for customizing. or corrosion resistance.

Aluminum knurled thumb screw is a type of thumb screw designed to be turned by hand. Metric Knurled Head Screws have a round head with knurls on the outer diameter that provide grip for a person to use to turn the screw.The aluminum knurled thumb screw are popularly used on: Safety covers for electronic gadgets. Battery covers of small electronic devices. High vibration Boats.
