Tips for best results: use a 2.5 mm Allen key for installation, apply steady, even pressure, and avoid over-torquing to protect threads. If load distribution is a concern, consider pairing with a washer for added surface contact and longevity. Store in a dry environment to preserve thread quality and extend the life of your hardware.
