Product Overview Security nut kit for rooftop tent mounting bolts — protects against theft on the trail and in parking lots. Includes 8 T-groove security nuts and a matching security tool for installation and removal. Fits standard M8 mounting bolts used on FSR rooftop tent crossbar mounts. Replaces standard hex nuts with tamper-resistant security hardware — no standard socket can remove them. A rooftop tent is a significant investment, and parking it in public — at a trailhead, a campground, or overnight in a city — means standard hex nuts are the only thing between your tent and someone with a socket set. The M8 Security Nut & Tool Kit replaces those standard nuts with T-groove security hardware that requires the included proprietary tool to install or remove. Eight nuts cover a full four-point crossbar mount. The tool stores in the tent or your kit; no standard socket removes the nuts without it.
