Description

Phillips Wafer Head Self Drilling Screws

Fuyang Metal is a professional Phillips wafer 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 global distributors, wholesalers and industrial buyers.

The wide, low-profile wafer head provides a larger bearing surface than a conventional pan head. This design distributes the fastening load over a wider area and helps reduce damage to thin sheet metal and other lightweight materials.

The integrated drill point drills and taps suitable metal sheets in one operation, helping reduce installation time. These screws are commonly used for light-gauge steel framing, metal profiles, sheet metal, HVAC equipment, electrical enclosures and industrial assembly.

Wide and Low-Profile Wafer Head Design

The wafer head, also known as a modified truss head, has a wide bearing surface and a relatively low installed profile. The large head helps distribute clamping pressure and provides stable fastening for thin metal sheets, profiles and lightweight components.

The Phillips recess is compatible with commonly available installation tools. Drive size can be matched to the screw diameter and customer requirements requirements fastening requirements.

Carbon Steel and Stainless Steel Options

Carbon Steel C1022 Drilling Screws

Heat-treated C1022 carbon steel provides good hardness and drilling performance. It is a cost-effective material for metal framing, sheet metal fabrication and general construction. Available finishes include zinc plating, black zinc, Dacromet, Ruspert, phosphating and customized coatings.

SS410 Wafer Head Drilling Screws

SS410 provides a useful combination of hardness, drilling capability and corrosion resistance. It is commonly selected when improved corrosion resistance is required without sacrificing the performance of the drill point.

SS304, SS316 and Bi-Metal Options

SS304 and SS316 offer higher corrosion resistance for humid, coastal and corrosive environments. Where both corrosion resistance and steel-drilling performance are required, a bi-metal construction with a stainless steel body and hardened carbon steel drill point may be considered.
