In this video we go over the differences between Grade 5 & Grade 8 bolts & hardware. We hope you found this interesting, please like and subscribe for future...
18 Σεπ 2024 · What is the difference between Grade 5 and Grade 8 bolts? Grade 5 bolts are medium-strength fasteners with tensile strength between 105,000-120,000 psi, while Grade 8 bolts are high-strength with tensile strength up to 150,000 psi.
There are several grades of bolts but the three common grades for SAE are 2, 5 and 8. The common class (grades) for metric are 5.8, 8.8, 10.9 and 12.9. Each grade has a specific bolt strength. No matter the system used, the higher number means the stronger the bolt.
A head with no markings is Grade 2, one with 3 lines spaced 120 degrees is Grade 5, and 6 lines spaced at 60 degree intervals is Grade 8. Nuts are marked in several different ways—see Identification Marks for Hex and Heavy Hex Nuts below.
9 Ιουν 2022 · Grade 2, 5, and 8 are the most common grades of fasteners according to the Society of Automotive Engineers standard. The higher the grade is, the stronger the material that makes up the fastener. The grade also represents the tensile strength, yield strength, and proof load of a fastener.
11 Σεπ 2023 · It is typically used for light-duty applications. Grade 5: A medium-strength grade. It is commonly used in construction and automotive applications. Grade 8: A high-strength grade. It is used in applications where high strength is required, such as bridges and heavy machinery. Grade 10: The strongest grade.
Before we delve into the differences between the grade 5 and grade 8, we need to learn how to identify the grade of a fastener using its head markings. Hex
