M8 Hex Bolts & Ball-Bearing T-Nuts for 8 mm Slot Profile – Set of 10 or 20

M8 hex bolts and ball-bearing T-nuts: overview

These sets pair carbon steel M8 ball-bearing T-nuts with M8 x 16 mm hex bolts – the standard fastener for mounting anything to 8 mm slot aluminium profile on a sim rig.

The spring ball holds each T-nut where you place it in the slot, so it doesn't drop to the bottom while you line up a bracket, and the large contact surface gives a strong, shock-resistant connection.

Choose 10 or 20 sets.

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. Slide the T-nut into the slot; the ball keeps it in place.
2. Line up your bracket and tighten the M8 bolt with a 6 mm hex key.

Care and maintenance

Do not over-tighten; store spares dry.
