Detailed Description
Black Double - Ended Bolts
These are black double - ended bolts, with common strength grades such as 8.8, 10.9, 12.9. Mostly made of carbon steel (with blackening treatment), they are used in scenarios like mechanical connection and equipment installation, playing a role in fastening. They belong to high - strength fasteners and can be customized with different lengths and thread specifications.
Instructions for Use:
Matching Check: Select the appropriate strength grade (e.g., 8.8, 10.9) and specification (length, thread size) according to the application scenario and load requirements.
Pre - use Inspection: Before use, check for damage, deformation, or thread abnormalities on the bolt body and threads.
Installation Requirement: When installing, cooperate with matching nuts at both ends, using tools like wrenches for fastening. Suitable for mechanical connection, equipment installation, etc.
Force Application: During installation, apply force evenly to avoid uneven stress causing bolt damage or connection loosening. Strictly prohibit over - force leading to thread damage.
Maintenance: Regularly check for rust, loosening, or thread damage in different environments. If defects affecting fastening performance are found, repair or replace the bolts promptly.
