DIN931 DIN933 HEXAGON HEAD BOLT GRADE 4.8 8.8 10.9 12.9

Bolt Standards:

1. DIN 931: Hexagon head bolts with a full thread

2. DIN 933: Hexagon head bolts with a partial thread

Strength Grades:

1) 4.8: Minimum tensile strength of 400 MPa (58 ksi)

2) 8.8: Minimum tensile strength of 800 MPa (116 ksi)

3) 10.9: Minimum tensile strength of 1000 MPa (145 ksi)

4) 12.9: Minimum tensile strength of 1200 MPa (174 ksi)

Material and Properties:

1. The bolts are typically made from alloy steel, with the higher grades (8.8, 10.9, 12.9) having a higher carbon and alloy content for increased strength.

2. The strength grades indicate the minimum tensile strength of the bolt material.

Applications:

Hexagon head bolts are used in a wide range of applications, including:

Structural steel connections

Machinery and equipment assembly

Automotive and transportation industries

General industrial and construction applications

Coatings and Finishes:

Hexagon head bolts can be supplied with various coatings or finishes, such as:

Plain (uncoated)

Zinc plated

Hot-dip galvanized

Stainless steel

The choice of coating or finish depends on the environmental conditions and corrosion resistance requirements
