Grade 14.9 represents a performance level for bolts/screws.
The yield strength of a 14.9 grade bolt is generally 240 MPa. 14.9 grade bolts are made of alloy steel material
The higher the grade of the bolt, the more prone it is to hydrogen embrittlement, but the higher the grade, the greater the hardness. Generally, we recommend that customers use grade 10.9 bolts more often
Relatively speaking, high-strength bolts of grade 10.9 have more stable performance.
