Megawatts of compute,
held by millimetre screws.
Power density pushes every rack joint to its limit: fans that vibrate for years, metals that expand at different rates, and assembly so dense that a stripped thread scrapes a board worth more than the whole fastener bin.
Fastening problems that only show up after year two
High-speed fan vibration works screws loose; dissimilar-metal joints relax through thousands of thermal cycles; and aluminum extrusion threads strip under repeated service. Our answer is clamp load that stays put: controlled-friction screws that give every automated driver the same torque-angle curve, pre-applied adhesive and sealing options that lock joints through cycling, and inserts that make aluminum threads serviceable.
- Controlled friction, µ = 0.09-0.15 - one torque program valid across every line
- Pre-applied adhesive and sealant options survive thermal cycling
- Thread inserts turn soft aluminum chassis threads into steel-grade wear surfaces
- Micro-to-M5 precision for dense board-level and module assembly

Torque is a proxy for clamp load only when friction is stable. With µ held to 0.09-0.15, the same torque setting yields the same preload on every screw, every line, every site - no per-line retuning, no under-clamped joints discovered in the field.
Wire-thread inserts and press-in bushings convert the joint into a steel wear surface: stronger first assembly, and repairable when boards are swapped across the server lifecycle.
Yes - adhesive and sealing materials are applied and cured under controlled process, so your lines skip a step and joints keep their locking performance through thermal cycling.
