What does 10 mean on a bolt head?
10: Metric bolts are marked with numbers that indicate the relative strength of the bolt. These numbers have nothing to do with the size of the bolt.
What is a Class 10 bolt?
Class 10. This is a metric nut grading similar to the SAE grade 8 classification, which is used in conjunction with Class 10.9 bolts. This strength of nut is used in automotive, and structural industries, as well as in high temp applications.
What does it mean if a bolt has 10.9 on the head?
The grade 8.8 refers to the tensile strength which is generally 116,000 psi, grade 10.9 is generally 150,000 and grade 12.9 is generally 175,000 psi.
What do the numbers on top of bolts mean?
Bolt Grade Markings
Each grade has a specific bolt strength. No matter the system used to grade the bolts, the higher number means the stronger the bolt. For most home and automotive applications, you won't need anything more than a grade 8 bolt strength or metric class 10.9.
What does 9.8 stamped on the head of a bolt mean?
Higher Number Means Stronger
A metric bolt designated as ISO class 6.8 roughly corresponds in strength to an SAE Grade 2 bolt. Bolts of ISO class 8.8 and the slightly stronger class 9.8 roughly correspond to an SAE Grade 5 bolt. An ISO Class 10.9 bolt roughly corresponds to an SAE Grade 8 bolt.
What is the strongest grade bolt?
Grade 9 structural bolts, also known as grade 9 hex cap screws, are one the strongest structural bolts that can be used today. While the typical grade 8 bolt has a tensile strength of 150,000 PSI, a grade 9 bolt has a tensile strength of 180,000PSI.
Is Grade 8 or 10.9 stronger?
Class 10.9 is stronger than class 8.8. It is commonly found in high strength automotive applications. Class 10.9 is similar to grade 8. A low carbon steel for general use.
What does 10.8 mean on a bolt?
This number is 10% of the minimum tensile strength of the bolt (10% of proof strength for nuts). Thus, multiplying this number by 10 will produce the minimum tensile strength of the fastener in MPa.
What is meaning for high strength bolt 8.8 s and 10.9 s?
The high-strength bolt is generally made of high-strength steel (45 steel (8.8s), 20mtib (10.9s), which is a prestressed bolt. The friction type uses a torque wrench to apply the specified prestress, and the pressure type screws off the plum head.
What size is a 10.9 bolt?
The 10.9 grade has around 10.9mm diameter and the applications range from motors, engines, railroad equipment and processing equipment. The Class 10.9 Alloy Steel Hex Bolts have a hexagonally shaped head that could be used with appropriate tools for maximum tightening. This is the most common shape of the bolts.
What does 11 mean on a bolt?
The “11” is a manufacturer mark. You would want a Grade 8 bolt to replace it.
Whats stronger Grade 8 or Grade 5 bolt?
Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions. Grade 8 bolts have 6 evenly spaced radial lines on the head.
