Description

Fuyang Metal is a professional hex socket button head self drilling screws manufacturer in China. We manufacture carbon steel C1022, stainless steel SS410, stainless steel 304, stainless steel 316 and customized drilling screws for distributors, wholesalers and industrial buyers.

The internal hex socket provides positive tool engagement and efficient torque transfer during installation. The low-profile button head offers a clean appearance and distributes the fastening load over a broader surface than many conventional screw heads.

The integrated drill point can drill, tap and fasten suitable metal sheets in one operation. These screws are suitable for metal fabrication, equipment assembly, electrical enclosures, steel profiles and other applications where a hex socket drive is preferred.

Internal Hex Socket Drive

The internal hex socket, also known as an Allen drive, provides positive engagement between the screw and installation bit. This drive design helps transfer installation torque efficiently and provides a neat appearance after fastening.

Hex socket dimensions can be selected according to the screw diameter, head dimensions, installation torque and customer drawing.

Carbon Steel and Stainless Steel Options

Carbon Steel C1022 Drilling Screws

Heat-treated C1022 carbon steel provides good hardness and drilling performance for metal-to-metal fastening. Available finishes include zinc plating, black zinc, Dacromet, Ruspert and customized corrosion-resistant coatings.

SS410 Socket Drive Drilling Screws

Stainless steel SS410 combines useful corrosion resistance with the hardness required for drill-point performance. It is suitable for many outdoor, construction and industrial fastening applications.

SS304, SS316 and Bi-Metal Options

SS304 and SS316 provide increased corrosion resistance for humid, coastal and corrosive environments. A bi-metal design may be used when a corrosion-resistant stainless steel body and stronger carbon steel drill point are both required.
