Spring-loaded T-nuts for 4040 sim racing rigs. The single most-used fastener in any aluminum extrusion build — for mounting monitors, button boxes, shifters, handbrakes, dashboards, and every accessory between. Available in M6 or M8 thread sizes, in three pack quantities so you only buy what you need.
Why spring T-nuts beat drop-in nuts
Standard drop-in T-nuts fall out the moment you tilt your profile — turning every install into a juggling act. Our spring-loaded T-nuts grip the slot wall the second they're inserted and stay exactly where you put them. Slide them anywhere along the extrusion (even after the rig is assembled), position your bracket or mount, and tighten. Faster installs, cleaner alignment, painless adjustments later.
Choose your thread size
-
M6 — the standard for 4040 rig hardware. Use for monitor mounts, button boxes, shifter posts, handbrakes, dashboards, accessory mounts, and most general-purpose attachments. Matches the M6 hardware in our 4040 Corner Bracket Kit.
-
M8 — heavier-duty option for high-stress mounting points. Use for direct drive wheelbase mounts, pedal plate mounts, seat slider mounts, and any connection that needs maximum holding force.
Choose your pack size
-
10-Pack — for replacing missing hardware, adding a single accessory, or topping up your spares drawer.
-
20-Pack — the sweet spot for adding multiple accessories or completing a partial build. Better per-nut value than the 10-Pack.
-
50-Pack — bulk pack for full rig builds, multi-monitor setups, or rig builders who go through T-nuts fast. Best per-nut value.
Built for sim racing rigs
Designed for 40-series aluminum extrusion with 8mm T-slots — the industry standard used by major sim racing brands including Sim-Lab, Trak Racer, GT Omega, SimXPro, and virtually every DIY cockpit build.
