Button Head Cap Screw Iso-7380

Description

HBS Fasteners manufactures premium Button Head Cap Screws in accordance with the ISO 7380 standard. These fasteners are characterized by their distinct “button” or “dome” shaped head, which is significantly lower in profile than a standard socket cap screw. The rounded edges of the head reduce the risk of snagging on clothing or moving parts, making them the ideal choice for exposed assemblies. Driven by an internal hex (Allen) key, they provide high torque transfer while maintaining a clean, modern appearance.

Technical Specifications

• Standard: Manufactured strictly to ISO 7380-1 (Plain) and ISO 7380-2 (with Flange) specifications.

• Head Style: Rounded Dome/Button head for a smooth, low-profile finish.

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

• Thread Type: High-precision Metric machine threads (Coarse and Fine pitch available).

• Size Range: Available from M3 to M16 in various lengths to suit diverse industrial needs.

Material & Quality Excellence

• Stainless Steel: Available in A2 (304) and A4 (316) for superior corrosion resistance in food, medical, and marine industries.

• Other Materials: Produced in Grade 10.9 and 12.9 High-Tensile Alloy Steel for applications requiring high strength-to-weight ratios.

• In-House Control: Utilizing raw materials from our own wire drawing facility, we ensure that the dome head is perfectly centered and the socket is forged to exact tolerances to prevent slipping during high-torque assembly.

• Surface Finishing: Options include Black Oxide, Zinc Plating (Clear/Yellow), and specialized aesthetic coatings like Chrome or Nickel.

Key Application Areas

• Consumer Electronics: Securing casings and internal components where a flat, sharp-edged screw might cause damage.

• Automotive Customization: Widely used in trim, interior panels, and motorcycle fairings for a professional, customized look.

• Safety Equipment: Ideal for handrails, playground equipment, and public furniture where protruding sharp edges must be avoided.

• Automation & Robotics: Used in frame assemblies where a low-profile fastener is needed to prevent interference with sensors or moving arms.
