Wafer Head Self-Tapping Screws
Product Overview
This product is a US-standard 10-24×13 cross-recessed tri-lobed self-tapping screw, made of carbon steel, heat-treated for increased hardness, and surface-coated with a blue, eco-friendly Rust-Proof coating. The head features an integrated flanged waffle design with anti-slip serrations, and the triangular pointed tip enables self-tapping thread forming without the need for pre-tapped holes. It requires no separate washers, offering vibration resistance, anti-loosening performance, and long-lasting corrosion protection. It is an advanced fastener ideal for sheet metal and outdoor equipment applications.
Product Applications
Fastening thin sheets in industrial equipment such as control cabinets and instrument panels;
Outdoor hardware applications, including aluminum doors/windows, curtain walls, and photovoltaic mounting structures;
Assembly of plastic and metal components in air conditioners, small appliances, and automotive interiors;
Export and foreign-trade equipment requiring compliance with EU and US environmental standards.
Product Features
Waffle Anti-Slip Flange Head: The serrations on the underside bite into the workpiece, providing vibration resistance and preventing loosening; the integrated flange eliminates the need for separate washers, reduces the risk of damaging thin sheets or plastics, and the cross-recess allows for convenient installation and removal.
US-Spec Tri-Lobed Self-Tapping Thread: The 10#-24 coarse thread ensures secure fastening, while the triangular pointed tip enables direct self-tapping into materials; the 13mm shank length suits general panel assembly applications.
Long-Lasting Corrosion-Resistant Coating: The chromium-free, eco-friendly Rust-Proof coating delivers superior salt spray performance compared to conventional zinc plating, resists moisture and saline corrosion, and maintains color fastness with good wear resistance.
Hardened Carbon Steel Substrate: Adequate hardness ensures reliable performance across a range of materials, including steel plates, aluminum extrusions, plastics, and wood, with reduced risk of tip breakage or thread stripping.
