Door Closer Sex Bolts – 4-Pack Thru-Bolt Mounting Kit

The permanent fix for door closers that won't stay put. This thru-bolt kit creates a holding strength that standard screws simply can't match — the closer stays mounted, no matter how hard the door gets slammed. Works on aluminum frame, glass, composite, wood, or any door material.

One 4-pack = one complete door closer installation. Trusted by contractors and facility managers. Easy enough for a confident DIYer.

Why Thru-Bolt Instead of Standard Screws?
Standard screws bite into the surface layer only — on aluminum frames, hollow cores, or high-traffic doors, they work loose and eventually fail. Thru-bolts pass completely through the door and clamp from both sides, spreading the load across the full door thickness. The result: a mount that holds for the life of the closer.
