M8 x 20 mm hardened flat-head screws: overview

Mounting on aluminium profile rigs

The 8 mm slot standard. Most modern sim rigs use 40 mm-based aluminium extrusion (40x40, 40x80, 40x160) with 8 mm slots. Mounts fix with M8 bolts and T-nuts that slide into the slot, so they can be moved and re-angled at any time.

Rigidity and access. Mount heavy or high-force devices (handbrakes, shifters, wheel bases) as close to a vertical upright or cross member as possible. Leave room to get in and out of the seat.

Tools. A set of hex keys (mainly 6 mm for M8) covers nearly every mount. Snug every bolt, test, then do a final tightening once the position is right.

Setup and use

1. Insert with an M8 T-nut in the slot.
2. Tighten with a 5 mm hex key.

Care and maintenance

Avoid over-tightening into aluminium.
