These bolts are manufactured to grade 8.8 specifications.
These bolts are fully threaded.
No, the package includes 5 bolt fasteners only.
While durable, they are standard steel; if used outdoors, we recommend applying a rust-preventative coating or using them in sheltered environments.
The length of these bolts is 90mm.
You will need a standard metric wrench or socket compatible with an M8 hex head.
Check if the mating nut is also M8 and verify if the threads are stripped. If the hole is worn, consider using a thread locker.
Ensure you are using the correct metric wrench size; do not use standard/imperial wrenches as they may damage the bolt head corners.
To install these bolts, use a standard metric wrench or socket that matches the M8 hex head size. Ensure the mating surface is flat to distribute pressure evenly across the bolt head. It is recommended to use a compatible flat washer to prevent surface damage during tightening. For outdoor or high-corrosion environments, consider applying a light coat of anti-seize lubricant to the threads during installation. Keep the bolts stored in a dry environment to maintain their grade 8.8 finish and prevent surface oxidation.
