Drill  screws are a new type of efficient riveting fasteners; Also known as self drilling self tapping screws, drilling tail screws, drilling tail screws, drilling tail screws, self drilling screws, drilling tail self tapping self drilling screws, etc. The tail of the drill tail screw has a self drilling head that is in the shape of a drill tail or a pointed tail. When riveting the connected part with the drill tail screw, there is no need for auxiliary processing on the surface and inside of the connected part. The drill tail screw can be directly drilled, threaded, and locked on the set material and basic material in one go, and can be quickly and automatically drilled and directly tightened for fixation.
Special process and characteristic advantages:

1. The surface is galvanized, with high brightness and beautiful appearance, and strong corrosion resistance (optional surface treatment processes include white zinc plating, color zinc plating, black phosphating, gray phosphating, and nickel plating).
2. Carburization and tempering treatment can achieve or exceed standard values with high surface hardness.
3. Advanced technology, low torque, and high locking performance.
The optimal drilling steel plate thickness should not exceed 6mm
Pan cake head” refers to the type of head on a screw, which is flatter and wider than a typical screw head. “Self-drilling” means that the screw has a drill-like point, allowing it to go into material without the need for a pilot hole. These types of screws are commonly used in construction, especially for metal-to-metal and metal-to-wood applications. Is there anything specific you would like to know about pan cake head self-drilling screws?

The tail of the self-drilling screw has a tail-drilling or pointed tail shape, and no auxiliary processing is 
required. It can be directly drilled, tapped and tightened on the set material and basic material, which
greatly saves construction time.Compared with ordinary screws, its toughness and holding force are high,
and it will not loose after a long time after combination.
It is easy to complete the operation by using safety punching and tapping at one time.It is a kind of screw, 
which is mainly used for fixing the color steel tile of steel structure and can also be used for fixing of thin
 late of simple construction.It cannot be used for metal-to-metal bonding and fixing.

Standard slot:Round head ,quickly install, save the time.
Thread complete: smooth and burr-force the force is even not easy to lose teeth
Non-isosceles tail:prevent cracking,reduce screwing resistance high-strength screwStainless steel materia
beautiful appearance
waterproof
anti-rust
