Choose a riving head with the same diameter as the expansion screw casing, and install it on an electric drill to punch holes. The depth of the hole should be equal to the length of the bolt. Then insert the expansion bolt group into the hole. Remember: When the drill bit is too deep, be sure to unscrew the nut to prevent the bolt from falling into the hole.
Tighten the nut for 2 to 3 buckles, and unscrew the nut when the expansion bolt is very tight and not loose. Then install the fixing piece on the fixing piece with holes, and align the bolts for installation. Spacers or spring washers on the outside are used to tighten the nuts.
Notes:
1. Please allow slight size errors due to manual measurement.
