2019年10月11日 · 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. The nominal tensile strength of bolt material is 400 MPa. The yield-strength ratio of bolt material is 0.8. The nominal yield strength of bolt material is 400 x 0.8=320 MPa.

2009年4月28日 · 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.

Metric steel bolts, screws and studs - proof and tensile strength. 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. Bolts, nuts and threaded rods - torque, tension and loads.

2025年1月2日 · The grade of bolts represents its material strength and performance, and bolts of grade 4.8 and grade 8.8 are common grades. This article will explain in detail the meaning of bolt grade 4.8 and compare it with grade 8.8 bolts to help readers better understand their differences and applicable scenarios.

2022年3月28日 · Generally used bolt grades in the market are 4.8, 8.8, 10.9, and 12.9. 3.6. 4.6. 4.8. 5.6. 5.8. 6.8. 8.8. 9.8. 10.9. 12.9. Below is a metric bolt grades chart that is used to identify the bolt head markings and their mechanical properties including strength and hardness.

The grade 4.8 bolt is a standard specification of low or medium carbon alloy grade. Grade 4.8 Bolts can be either fully or partially threaded. These bolts have an external male thread that has a matching female thread. The class 4.8 bolts can be easily assembled, making use of nuts or washers to securely affix the material efficiently.

A chart to identify bolt grades using bolt grade markings; also provides a strength chart for common grade bolts.

ASTM F568 Grade 4.8 is a material specification for high tensile carbon steel bolts, stud bolts, screws, threaded rods, for high temperature or high pressure applications.

Hex bolt grade 4.8 is hex bolt with tensile Strength = 400 N/mm2 and yield Strength = 320 N/mm2. We have a variety of products such as hex head bolt m8.
