Allen Grub Screw is a type of screw that features an Allen (hexagonal) drive and is designed to be inserted into a threaded hole without protruding beyond the surface of the material. Grub screws are often used for various applications, including securing one component within another or providing a flush surface when tightened.
When using Allen grub screws, it's important to ensure that the size, material, and threading are suitable for the specific application. Additionally, proper torque control is essential to prevent over-tightening and potential damage to the threaded components.

Allen Grub Screws are a type of fastener, in some ways similar to a bolt, typically made of metal, and characterized by a helical ridge, known as a male external thread. Allen Grub Screws are used to fasten materials by digging in and wedging into a material when turned, while the thread cuts grooves in the fastened material that may help pull fastened materials together and prevent pull-out. There are many Allen Grub Screws for a variety of materials; those commonly fastened by Allen Grub Screws include sheet metal, wood, and plastic.
Zinc and Chromate Allen Grub Screws: Silvery and offers resistant to corrosion for Allen Grub Screws.
Plain Finish Allen Grub Screws: Allen Grub Screws with No Coating.
Zinc Plated Allen Grub Screws: Allen Grub Screws Coated with Zinc.
Zinc and Yellow Chromate Allen Grub Screws: Offers better resistant to corrosion to Allen Grub Screws than Chromate.
Hot Dipped Galvanized(HDG) Allen Grub Screws: Offers superior resistant to corrosion due to the dipping of Allen Grub Screws in the molten zinc.
