Detalles del producto

Our DIN 916 set screws are engineered for superior performance and durability in demanding applications. They are headless, fully threaded fasteners that function by being driven into a threaded hole until the point exerts a strong compressive force on an inner object, locking it securely.

• DIN 916 Standard with Cup Point Design: Manufactured in strict accordance with the DIN 916 standard (equivalent to ISO 4029), these screws feature a cup point. This concave, cup-shaped tip is designed so that its sharp circular rim bites into the surface of the shaft upon tightening. This action creates a strong mechanical lock that offers excellent resistance to both rotational (torsional) and axial slippage, especially under conditions of heavy vibration.
• High-Strength Alloy Steel with Black Oxide Finish: These screws are crafted from high-quality carbon and alloy steels (such as 4140) and are heat-treated to achieve high property classes, including 8.8, 10.9, and 12.9. This ensures the screw has the necessary hardness and tensile strength to withstand high installation torques and maintain its grip under load. The black oxide coating provides moderate corrosion resistance for indoor or lubricated environments, prevents thread galling, and offers a durable, non-reflective finish.
• Accionamiento hexagonal: The deep, clean internal hexagon socket (Allen drive) allows for high-torque installation with a standard hex key. This enables the screw to be set flush with or recessed below the component’s surface, resulting in a safe, compact assembly with no dangerous protrusions.

The technical specifications for our DIN 916 High-Strength Cup Point Grub Screws are outlined below to meet your precise engineering requirements.

Características del producto

Our DIN 916 cup point grub screws are the go-to choice for high-strength fastening due to their exceptional features.

• Superior Holding Power: The cup point’s circular rim digs into the shaft material, creating a powerful grip that provides excellent resistance against axial and torsional loads.
• Excellent Vibration Resistance: The mechanical lock created by the biting edge makes the cup point design highly resistant to loosening caused by vibration, ensuring a secure and reliable assembly.
• High Strength and Hardness: Made from heat-treated alloy steel, these screws possess the high tensile strength and surface hardness required for demanding, high-torque applications without deformation.
• Diseño seguro y sin cabeza: The ability to install the screw flush with the surface eliminates dangerous protrusions, making it ideal for rotating or moving assemblies where safety and clearance are critical.
• Versatile and Cost-Effective: As the most common type of set screw, the DIN 916 cup point offers a reliable and economical solution for a vast range of general-purpose and high-strength locking applications.

Aplicaciones de los productos

DIN 916 high-strength cup point grub screws are indispensable in virtually every mechanical and industrial sector. They are the primary choice in transmisión de energía for securing pulleys, gears, sprockets, and shaft collars. In automotive systems, they are used to lock components in engines, transmissions, and drivetrains where high vibration is present. They are essential in industrial machinery for fixing parts in machine tools, conveyor systems, and automated equipment. They are also widely used in tooling and fixturing for setting adjustments and securing components in jigs and fixtures. Their combination of strength, reliability, and versatility makes them a fundamental component in modern engineering.
