What is ISO 10664:2014-Hexalobular internal driving feature for bolts and screws?
ISO 10664:2014 specifies the design and dimensions of hexalobular internal driving features for bolts and screws. The hexalobular internal driving feature is also known as the Torx® drive system, which is a type of fastener drive system that uses a six-pointed star-shaped pattern to transmit torque.
ISO 10664 applies to bolts and screws with hexalobular internal driving features, which are commonly used in a wide range of industries, including automotive, aerospace, construction, and electronics. The standard specifies the geometry and dimensions of the hexalobular internal driving feature to ensure compatibility between different manufacturers and to ensure that the fasteners can be installed and removed easily and securely.
It also includes recommendations for the materials, tolerances, and testing procedures for hexalobular internal driving features. This information is intended to ensure the quality and reliability of fasteners with hexalobular internal driving features.
ISO 10664:2014 is an important standard for the design, manufacturing, and use of hexalobular internal driving features in bolts and screws. It helps to ensure that these fasteners are compatible, reliable, and easy to use, which can improve safety and efficiency in a wide range of applications.
Requirements of ISO 10664:2014
Geometry and dimensions: The standard specifies the geometry and dimensions of the hexalobular internal driving feature, including the number of lobes, the size of the lobes, and the spacing between the lobes. These specifications ensure that this method is compatible between different manufacturers and that it can transmit torque efficiently.
Tolerances: ISO 10664 specifies the tolerances for the dimensions of the hexalobular internal driving feature, which helps to ensure that the feature is consistently manufactured to the required specifications. Tolerances are also specified for the length and diameter of the screw or bolt.
Material: The standard recommends that the feature be made from a high-quality, durable material that is resistant to wear and tear. The material should also be capable of withstanding the required torque and load.
Testing: This standard recommends testing procedures for hexalobular internal driving features to ensure that they meet the required specifications. Testing procedures may include torque testing, axial load testing, and torsional strength testing.
Benefits of ISO 10664:2014
Improved compatibility: The standard specifies the geometry and dimensions of the hexalobular internal driving feature, which helps to ensure compatibility between different manufacturers. This can reduce the risk of issues with fastener installation and removal due to incompatible tooling.
Increased torque transmission: The six-pointed star-shaped pattern of the hexalobular internal driving feature provides more points of contact for torque transmission compared to other drive systems. This results in improved torque transmission and reduces the likelihood of tool slippage, which can help to prevent damage to the fastener or surrounding components.
Reduced risk of damage to fasteners: This standard specifies the material and tolerances for the hexalobular internal driving feature, which helps to ensure that it is durable and resistant to wear and tear. This can reduce the risk of damage to the fastener during installation and removal.
Enhanced safety: These features can help to improve safety by reducing the likelihood of tool slippage and damage to the fastener or surrounding components. This can be particularly important in applications where safety is a critical concern, such as aerospace or automotive applications.
Ease of use: It is easy to use, even in applications where access is limited. This can save time and effort during installation and removal, particularly in tight spaces or other difficult-to-reach locations.
ISO 10664:2014 helps to ensure bolts and screws are reliable, easy to use, and compatible between different manufacturers. This can provide several benefits for a wide range of industries, including improved efficiency, reduced downtime, and increased safety.
Who needs ISO 10664:2014-Hexalobular internal driving feature for bolts and screws?
Manufacturers of bolts and screws can use ISO 10664 to ensure that their products meet the standard’s requirements for the geometry, material, and tolerances of hexalobular internal driving features.
