Brass Countersunk Bolts
DIN 7991 and ISO 10462-compliant brass countersunk bolts, also known as hexagon socket countersunk head screws, feature a hex socket drive that offers superior cam-out resistance compared to traditional drives like slotted or Phillips. These screws are designed for quick installation using a hex wrench or insert bit and provide a flush, polished finish that reduces snagging and potential injury.
Brass countersunk bolts compliant with DIN 7991 and ISO 10462 standards, known as hexagon socket countersunk head screws, feature a hex socket drive for enhanced cam-out resistance compared to traditional slotted or Phillips drives. These screws can be installed swiftly and securely into a countersunk hole using a hex wrench or insert bit. Once installed, they offer a sleek, flush finish that minimizes the risk of snagging or injury.
Their distinctive gold-like sheen makes them popular across various industries, particularly in historical mechanical and engineering applications. Made from brass, these screws are highly resistant to rust, corrosion, and offer antibacterial properties, making them suitable for outdoor and self-sterilizing uses.
Additionally, screws are available in other materials such as A2 stainless steel, A4 stainless steel, aluminum, and titanium. Standard lengths range from 10mm to 90mm with thread sizes from M4 to M16, and thread locking options are also available. Custom orders for non-standard sizes, materials, and finishes, including small-batch production and tailored components, can be accommodated.
Countersunk bolts are used when a smooth surface is required. Common applications include: bridge decking, walkways, and railing.
