Fasteners 101: Bolt Selection Tips
Bolted joints are essential for several applications across many industries. From engineering to construction, manufacturing, DIY projects, etc., having suitable bolt systems is pivotal to ensuring your joints' strength and structural integrity. Bolts come in all sizes and shapes. Therefore, ensuring you get the correct type is crucial because even the slightest variations in the properties of your bolt can make all the difference in your application and compromise the bolt's efficiency. Therefore, it's essential to consider several factors to narrow down your options to one that best suits your needs. Here are a few guidelines to help you in your selection.
Choose The Size Carefully
Size is one of the most crucial aspects to consider when choosing bolts. Bolts come in different sizes to fit unique applications needs. Generally, bolt size covers the length and diameter of the bolt. And many objects typically come with the manufacturer's recommendation for the correct bolt size. The bolt's diameter will determine whether or not it will fit the bolt holes of your application. Therefore, make sure you get this size correct because too wide a bolt will be impractical, while one that's too narrow won't get the job done right, and you may end up with weak joints.
On the other hand, pay extra attention when measuring the length of your bolts. That's because how you measure the length varies depending on the bolt type. For instance, if you buy hex bolts, your measurements should start from under the bolt head to the end. On the other hand, if you choose countersunk bolts, you should consider the bolt's overall length. Fortunately, you can get away with longer-than-needed bolts by simply cutting off some of the extra length. However, this may not be the case for bolts that are too short for the intended purpose. Therefore, ensure you get the measurements right to avoid issues down the line.
Consider The Function
Bolts have multiple functions. Therefore, it would be best to assess your needs thoroughly to ensure you select the most suitable type. For instance, most joints or applications require a bolt and nut system. However, some bolts are designed to go into threaded bolt holes. Therefore, think about what you need your bolt to do before buying one to ensure it's the correct choice for your application.
Think About the Thread Pitch
Bolts come in two primary thread pitch options: coarse thread and fine thread. Therefore, be sure to ask about the thread pitch when choosing one. Generally, coarse threads have fewer threads than their fine thread counterparts. Therefore, they tend to install faster. However, fine thread bolts are typically stronger and can generate more clamp force.
