Review on Exterior BLAKOTE Ceramic Makers Bolt by Nate Jenkins

Pre-drilled to thread into studs. I used my drill bit with a 3/8 drive head for the connector screws, but adjusted the torque on the bit so I didn't overtighten or tear the drywall. Finish tightening with a wrench so each locking bolt securely secures the floating shelves. Dewalt 20v battery and torque set to 9 to drive the bolts. Then finish with a wrench.
