Product Details

Our ISO 7380 Button Head Bolts are precision-manufactured to meet the highest international standards, ensuring consistent quality and fit. The defining feature is the smooth, rounded button head, which offers a wide bearing surface to distribute clamping force and prevent damage to softer materials, often eliminating the need for a washer. The fastener is driven by a clean, deep internal hex socket (Allen drive) for positive tool engagement and precise torque control.

These bolts are available in several grades of stainless steel to meet specific environmental and strength requirements:

• A2 Stainless Steel (SS304): The industry standard for general-purpose applications. It offers excellent corrosion resistance in most atmospheric conditions and is suitable for a wide range of indoor and outdoor uses.
• A4 Stainless Steel (SS316): The premium choice for harsh environments. With added molybdenum, A4 grade provides superior resistance to chlorides (such as saltwater), acids, and other chemical agents, making it essential for marine, coastal, and chemical processing applications.
• SS201 Stainless Steel: A cost-effective alternative for dry, indoor environments where high humidity and corrosive elements are not a concern.

The bolts are supplied with a plain, passivated finish, which enhances the natural chromium oxide layer on the steel’s surface for a self-healing, maintenance-free barrier against rust.

Product Parameters

The technical specifications for our ISO 7380 Stainless Steel Hex Socket Button Head Bolts are outlined below, ensuring they meet the exact needs of your project.

Product Features

Our stainless steel ISO 7380 bolts offer a unique set of advantages that make them a superior choice for quality-critical applications.

• Permanent and Inherent Corrosion Resistance: Unlike plated fasteners, the corrosion protection is integral to the stainless steel itself. It will not chip, flake, or wear away, ensuring long-term integrity and appearance, especially in outdoor and wet conditions.
• Aesthetic and Safe Design: The smooth, low-profile dome head provides a clean, modern, and professional finish. Its rounded shape has no sharp edges, making it safe for accessible areas and preventing snags on clothing or wiring.
• High Strength and Durability: Available in high-tensile grades like A2-70 and A4-80, these bolts are work-hardened to provide significant strength, making them suitable for both decorative and light structural applications requiring reliability.
• Hygienic and Easy to Clean: The non-porous and corrosion-resistant surface of stainless steel is easy to sterilize and does not harbor bacteria, making it the ideal material for food-grade equipment, medical devices, and pharmaceutical manufacturing.
• Reliable and Precise Installation: The internal hex socket allows for accurate and high-torque tightening without the risk of cam-out or tool slippage, ensuring a secure and vibration-resistant connection.

Product Applications

The exceptional properties of our stainless steel ISO 7380 button head bolts make them indispensable across a wide range of demanding industries. They are essential in marine applications for boat building, deck hardware, and coastal fixtures where resistance to saltwater is critical (A4/316 grade). In the food and beverage industry, they are used to assemble processing equipment, conveyors, and preparation surfaces. The medical field relies on them for manufacturing surgical instruments, hospital equipment, and laboratory devices. They are a favorite in architecture and construction for installing glass balustrades, decorative panels, and high-end signage. They are also widely used in automotive and motorcycle customization, electronics, and any precision equipment where performance, longevity, and appearance cannot be compromised.
