LN29671AM6 Fixed Anchor Nut Plate, M6x1.00 Thread, Two-Lug Non-Floating, Self-Locking

LN29671AM6 – M6x1.00 Fixed (Non-Floating) Anchor Nut Plate

Genuine aerospace-standard fixed anchor nut in M6x1.00 thread — the clean, professional way to create captive threaded mounting points on panels, bulkheads, floors, and chassis structures where you can’t get a wrench behind the work. Rivet it in once, and every future panel-off is a one-tool job.

Manufactured to the German aerospace standard DIN LN 29671 (self-locking, double-lug anchor nuts rated for service temperatures up to 235°C / 455°F), these are the same nut plates used throughout the aircraft industry — and for the same reasons they’ve become standard practice on formula cars, sports racers, and GT cars: light weight, all-metal vibration-proof thread locking, and permanent installation that survives hundreds of service cycles.

Why Fixed (Non-Floating)?

The non-floating design holds the threaded barrel rigidly in position — ideal for precisely located mounting points where you control the hole position, such as jig-drilled brackets, floor mounting hardware, undertray attachment, and bodywork fastener points. The fixed barrel gives a solid, rattle-free anchor with no float cage to fatigue. (If your application needs positional forgiveness for hole misalignment, use the floating version instead — see related products.)

Features

• All-metal self-locking thread — deformed-thread prevailing torque design, no nylon insert to melt, age, or wear out. Effective at engine-bay and brake-area temperatures up to 235°C (455°F), and reusable through repeated panel removal cycles
• Two-lug riveted mounting — installs permanently with two rivets (countersunk or dome-head solid/blind rivets), keeping the fastening flush and secure on the blind side of the panel
• Alloy steel construction — heat-treated aerospace alloy steel (42CrMo4-class) with corrosion-resistant plating and low-friction thread coating for consistent torque
• Aerospace pedigree — produced to DIN LN 29671; the metric equivalent of the familiar US MS21047-style two-lug nut plate (there is no US MS standard for metric nut plates, making the LN series the metric standard worldwide)

Typical Motorsport Uses

• Floor and undertray mounting points
• Bodywork, nose box, and engine cover attachment
• Access panels and inspection covers
• Seat, ballast, and electronics tray mounting
• Any blind location where a captive M6 thread beats a loose nut and washer

Installation Tips

Drill the bolt clearance hole first, then use the nut plate itself (threaded onto a bolt through the panel) as the drill template for the two rivet holes — this guarantees alignment on a fixed nut plate. Rivet with 3/32″ or metric-equivalent solid or blind rivets depending on panel material and access. For countersunk installations, dimple or countersink the panel to keep the mounting flush.
