Flange Button Head Cap Screw

Description

HBS Fasteners manufactures premium Flange Button Head Cap Screws, designed for maximum efficiency in modern assembly lines. By incorporating a wide, flat flange into the base of the dome head, this fastener distributes the tightening pressure over a larger area. This prevents the screw from crushing or sinking into soft materials like plastic, aluminum, or thin sheet metal. The internal hex (Allen) drive allows for high torque application, while the low-profile dome provides a sleek, snag-free finish.

Technical Specifications

• Standard: Manufactured in accordance with ISO 7380-2.

• Head Style: Rounded Button/Dome head with a built-in circular flange.

• Drive Type: Internal Hexagon Socket (Allen Drive) for precision tightening.

• Design Advantage: “Two-in-one” design (Screw + Washer) reduces part count and speeds up assembly time.

• Size Range: Available in metric diameters from M3 to M16 with various thread lengths.

Material & Quality Excellence

• Stainless Steel: Available in A2 (304) and A4 (316) for high-grade corrosion resistance, ideal for outdoor and marine use.

• Other Materials: Produced in Grade 10.9 and 12.9 High-Tensile Alloy Steel for structural and mechanical applications.

• In-House Control: Using raw materials from our own wire drawing facility, we ensure the flange thickness and head symmetry are perfectly maintained to provide a 100% flat bearing surface.

• Surface Finishing: Options include Zinc Plating (Trivalent), Black Oxide, and Nickel Plating for enhanced durability.

Key Application Areas

• Sheet Metal Fabrication: Perfect for securing panels and enclosures where a separate washer would be difficult to install.

• Automotive & Racing: Extensively used in bodywork, fairings, and engine bay aesthetics due to its clean look and secure grip.

• Furniture Manufacturing: Ideal for modern office furniture and shelving units where a wide clamping area is needed on wood or plastic.

• Bicycles & Sports Equipment: Widely used in bike frames and gear systems for its lightweight, low-profile, and aerodynamic properties.
