- WHAT DOES THE MEAN OF 4. 8 ON BOLTS | KYLT machined parts
X 100 = the tensile strength of the bolt, X 100* (Y 10) = the yield strength of the bolt (because the yield strength tensile strength = Y 10, i e 0 Y is the yield strength ratio) as specified in the label For grade 4 8, the tensile strength of the bolt is 400 MPa and the yield strength is 400*8 10=320 MPa
- bolts: metric standards - Sizes
In metric bolts, strength is described by “property classes ” A property class designation consists of two numbers separated by a decimal point There are nine commonly encountered: 4 6, 4 8, 5 8, 8 8, 9 8, 10 9 and 12 9
- Grades of Bolts - Bolt Grade Marking Chart | AFT Fasteners
These charts helps to identify the grades of bolts using the identification marks on the bolt's head along with the strength and hardness of common grade bolts Please note the bolt heads may also include the manufacturer's identification stamp, especially with high strength bolts
- Metric Steel Bolts - Grades and Property Classes
For metric bolts strength is according ISO 898 Mechanical properties of fasteners made of carbon steel and alloy steel described by "property classes" with designations 4 6, 4 8, 5 8, 8 8, 9 8, 10 9 and 12 9
- The difference between 4. 8 grade bolts and 8. 8 grade bolts
Bolts of grade 4 8 are suitable for some general low-strength connection scenarios, while bolts of grade 8 8 are suitable for occasions with higher connection strength requirements
- Difference between Class 4. 8 bolt and Class 8. 8 bolt
Class 4 8 is generally called ordinary bolts, and class 8 8 is called high-strength bolts General bolts can be divided into three grades: A, B, and C according to the manufacturing precision
- WHAT DOES THE MEAN OF 4. 8 ON BOLT? - zamakcast. com
The grade label of bolt performance consists of two parts, which represent the nominal tensile strength and yield strength ratio of bolt material 48 is 4 8 bolts Bolts performance grade: The nominal tensile strength of bolt material is 400 MPa The yield-strength ratio of bolt material is 0 8
- Understanding Metric Bolt Screw Grades — Head Markings!
So a Property Class 8 8 bolt or screw is a medium-strength fastener that’s roughly the same strength as an SAE J429 Grade 5 fastener The Property Class 10 9 head marking is shown here: Property Class 10 9 bolts and screws have a minimum tensile strength of 1040 MPa for all sizes
