Grade 8.8 refers to the tensile strength and yield strength of the steel; it is a standard metric designation for medium-strength high-tensile fasteners.
Yes, their high tensile rating is suitable for many structural automotive applications, but always consult your vehicle's technical manual for specific grade requirements.
Yes, as they are manufactured to DIN 933 standards, they feature full threading from the underside of the head to the tip.
While the galvanized finish is corrosion-resistant, it is not as effective as marine-grade stainless steel in constant saltwater exposure.
You will need a standard metric spanner or a six-point socket wrench matching the specific diameter of your setscrew head.
Check the hole for debris or cross-threading; if necessary, use a matching tap to clean the internal threads.
Ensure the spanner or socket is the exact size for the hexagon head and is fully seated before applying force.
Check if the galvanized coating was damaged during installation and touch up with a cold-galvanization compound if necessary.
To ensure maximum efficacy, always select a setscrew length that allows the thread to fully engage the mating part while providing enough protrusion for secure fastening. When installing, it is recommended to clean the receiving threads of debris or existing rust to prevent seizing. Although galvanized, if the coating is heavily damaged during installation, consider applying a cold-galvanizing spray to maintain corrosion resistance. Store these fasteners in a dry, low-humidity environment to preserve the integrity of the finish over long-term storage.
