Grade 10.9 denotes a high-tensile steel capable of withstanding high levels of force, commonly used in automotive and industrial machinery.
The black finish offers limited protection; for prolonged outdoor exposure, stainless steel alternatives are recommended.
You will need a standard metric hex key (Allen wrench) that fits the M6 socket size.
This model is an M6 diameter with a length of 40mm.
Yes, they can be painted, but ensure the surface is clean and dry to allow for proper paint adhesion.
Ensure you are using the correct size metric hex key and that the key is not worn down.
Verify the thread pitch matches your receiving hole and ensure there is no debris in the threads.
Clean the affected area and apply a protective oil or anti-corrosive sealant.
To install these screws, ensure your mating hole is correctly threaded for an M6 bolt. Use a high-quality hex key to avoid stripping the socket head during tightening. For applications subject to extreme vibration, consider using a thread-locking compound. To maintain the black finish, keep the fasteners in a dry environment; if installing in damp areas, a light coating of machine oil or a clear protective spray is recommended to prevent surface oxidation.
