在我们最新的博客文章中，我们回答有关不锈钢紧固件:
如何选择紧固件以进行特定用途？
There are several factors that come into play when you want to select a fastener for any application. These include:
- 必须考虑数量和/或所需紧固件的大小和/或强度。您必须使用Boltcalc等程序对这些因素进行分析。
- The best bolt material to withstand the elements in the area of application will determine which fastener will be suitable.
- 您将必须选择具有适当表面保护的钢紧固件，以防止腐蚀以及适合环境条件的材料。
You need to consider each application and analyze the requirements a fastener should meet before selecting the best material.
How Can I Easily Check The Torque Value on a Bolt?
当插座开始从拧紧的方向上移开拧紧的位置时，可以通过“破裂”方法检查螺栓的扭矩。
当插座开始从不稳定的方向上移开拧紧的位置时，您也可以使用“ crack”方法检查扭矩。如果将紧固件重新拧紧到明显的位置，则在紧缩的方向上，也可以检查扭矩。
Always apply torque in a slow and deliberate manner to minimize the dynamic effects on the gauge reading. Make sure the member that does not rotate stays put when checking the torque.
螺栓和螺钉之间有区别吗？
就在这里。而且，描述差异的最佳方法是了解您使用带有螺母的螺栓和螺栓的螺钉。
此外，螺钉是一种锥形紧固件，与现有螺纹键合或在旋转时将其螺纹创建在材料中。另一方面，螺栓是非锥形紧固件，需要垫圈和螺母将物体固定在一起。
我见过的大多数不锈钢紧固件都在头上有痕迹。这些是什么？
There are two types of marks on a bolt:
- 第一个是制造商或进口商的标记，它是识别制造商的符号，以及
- The second is the grade mark which is a standardized mark that identifies the material properties that the fastener meets.
We Need Help Because When We Tighten Stainless Steel Bolts, They Tend to Seize. Can You Kindly Assist?
冷焊接通常具有不锈钢材料。当金属形成氧化物以防止腐蚀时，就会发生这种情况。这导致拧紧期间的粘附问题增加。而且，在极端情况下，线程的实际冻结在一起。
您可以通过尝试以下操作来解决问题：
- Slowing down the installation RPM speed,
- Frequent lubrication of the internal and/or external threads, and
- Using different combinations of nut and bolt materials.
The Specifications on The Fastener Don’t Include The Shear Strength. How Can I Find It?
The shear strength of a steel fastener is about 0.6 times the tensile strength.
精细的螺纹紧固件是否比粗螺纹紧固件有任何独特的好处？
Yes, they do and these benefits include:
- 减少松动的趋势，
- 由于较小的音高，调整更精细，
- More strength size for size compared to a coarse thread,
- 更容易利用硬材料和薄壁管，以及
- 它们需要较少的扭矩才能产生等效螺栓预紧。
Why is Stainless Steel Used for Fasteners?
- Resistance to corrosion:不锈钢不会生锈，这意味着产品将持续更长的时间，并且腐蚀不会影响金属的磁性。
- Low maintenance:Stainless steel is easy to clean and since it’s resistant to corrosion and rust, it’ll consistently have a flawless look on its own.
- 价值：Stainless steel fasteners are quite expensive, but they are definitely worth the money since they can last for over 50 years.
- Strength:Stainless steel is incredibly durable and can withstand harsh weather conditions and corrosive environments.
What Are The 6 Basic Types of Fasteners?
- 螺丝：这是一个流行的紧固件，在旋转或固定成材料时会创建自己的线程。
- Nails:钉子是常见的家居用品，没有螺钉之类的线。指甲通常用于将木材和材料固定在金属，混凝土和砖石上。
- 螺栓Nuts:This is the most common type of threaded fastener that’s always used alongside a nut.
- Anchors:Anchor fasteners are usually used in construction and stone industries to connect structural and non-structural material to the concrete.
- 铆钉：铆钉是通过孔插入的机械紧固件，以连接多个零件。
- Washers:这些是薄板，中间有圆形孔。它们用于分配螺纹紧固件的负载，例如螺栓或螺母。
