Metal bolts are essential components of many items, from furniture to machinery and even vehicles. The grade of a bolt indicates its strength, ensuring it is capable of withstanding the load applied to it. However, with so many different grades and types of bolts available, it can be difficult to tell them apart and find the right one for the job. To help with this, there is a chart with bolt grade markings and strength information which provides an overview of the various types and grades of bolts.
What is Bolt Grade Markings and What does it Tell Us?
Bolt grade markings are a way of identifying the strength of the bolt. The markings usually consist of a series of numbers and letters, which can vary depending on the manufacturer. In general, the markings indicate the grade, thread, and type of bolt, as well as the material from which it is made. For example, a Grade 8 bolt is commonly marked 8.8, indicating an eight-grade bolt made of a medium carbon steel.
What is the Strength of a Grade 8 Bolt?
The strength of a grade 8 bolt is determined by the material from which it is made, as well as the thread size and length. Grade 8 bolts are typically made from medium-carbon steel or alloy steel and have a minimum tensile strength of 150,000 PSI. The thread size and length of the bolt will affect its strength, with longer or wider threads providing more strength.
