Future Classic BMW 54mm Classic Stud Kit. Just like the 80mm Future Classic steel stud, these have world-class, independently verified strength ratings (12.9+) thanks to its chromoly construction. As you'd expect from Future Classic, these are as beautiful as they are functional—a generous 6mm shoulder and buffer zone help safeguard against over-tightening while also adding a defining design cue. In contrast to FC's larger stud brethren, this shorty stud wears a small 24.5mm thread area, which makes a traditional "double nut" installation difficult. As a result (and to ensure adequate clearance with the closed-end cap), these 54mm studs bear a 5mm Allen key broach.
