Hexagon Flange Bolts with Reduced Shank

Hexagon flange bolts with reduced shank can prevent the exhaust pipe of a car from loosening. The diameter of the reduced rod part is small, allowing it to be inserted into narrower Spaces during installation. As the screw becomes thinner, less material is used, and the cost also decreases accordingly.

产品应用与参数

The use of hexagon flange bolts with reduced shank can prevent plastic garden sheds from cracking. When the material expands due to heat, the rod body will slightly bend. The flange can disperse the pressure and prevent thin-walled cracking. Therefore, there is no need to repair it with tape.

它们通常用于在狭窄的发动机舱内修理卡车。细长的杆体可以消除传感器或管线周围的障碍物，法兰部分则能防止螺栓晃动。镀锌层能有效抵抗路面溅水，维护时不会有螺栓头脱落的情况。

Hexagon flange bolts with reduced shank can be used to repair small machinery, such as electric shavers, small printers, etc. It can re-fix the parts in the narrow interior of the machinery, making maintenance more convenient and ensuring the normal operation of the machinery after repair.

成本与重量优势

Hexagon flange bolts with reduced shank are lighter than ordinary bolts. Because the reduced rod part reduces the amount of steel used, its price will be very cheap. They can be used in drones because the weight of the bolts is reduced and the performance of the drones is improved.

带有缩小柄的六角法兰螺栓有几种常见的表面处理选择。你选择合适的是根据螺栓的使用位置和防锈程度。

锌板是最常用的选择。它在螺栓表面覆盖一层薄薄的保护层，防止生锈和氧化。它便宜，适合日常室内使用或户外环境较轻的地方。

热浸镀锌也是一个选择。这个过程意味着将螺栓浸入熔化的锌中。这里的涂层比锌板厚，因此能更好地防腐蚀。它适合恶劣环境——比如沿海地区或建筑工地——这些地方的螺栓需要长时间抵御盐水或大量潮湿。

如果你想让螺栓看起来更好看，同时还能获得适度的防锈效果，可以选择镍镀层或镀铬层。

对于高温或化学环境中使用的螺栓，不锈钢钝化是首选。这种处理提升了不锈钢本身就具备的天然耐腐蚀性。

所有这些表面处理都遵循基本的工业规范。他们确保涂层粘得好、耐用，而且在组装螺栓时不会干扰它们的配合和工作。

Hexagon Flange Bolts with Reduced Shank are made to follow international standards like DIN 6921 and ISO 4014.

The common metric sizes have diameters from M6 to M24, and shank lengths that go from 10mm to 150mm. The reduced shank part is usually 1-2mm smaller than the bolt head diameter. That way, it fits standard pre-drilled holes without any hassle during assembly.

When it comes to strength grades, the two main choices are 8.8 and 10.9. Grade 8.8 bolts are made of medium carbon steel and heat-treated. They work well for regular industrial and automotive jobs. Grade 10.9 bolts are high-strength, made from alloy steel. They’re built for heavy-duty uses, like construction machinery or equipment that has to handle big loads.

Imperial sizes are also on offer. These have diameters from 1/4 inch to 1 inch, with lengths up to 6 inches.

Every bolt head has clear markings. You can see the strength grade and standard code right on it. The flange’s diameter and thickness match the relevant standards too, so it distributes load evenly when in use.
