Black 304 Stainless Steel Nylon Lock Nut (Pack of 10)

Black-finished 304 stainless steel nylon lock nuts, sold in packs of 10 in M2, M2.5 or M3 thread. The nylon insert grips the screw thread so the nut stays put under motor vibration and crash loads, which makes it the standard choice for frame arms, stack standoffs and camera mounts that must not work loose.

Key features

• Three thread sizes: M2 and M2.5 for whoop and micro builds, M3 for 30.5x30.5 stacks and 5-inch-and-larger frames
• Nylon locking ring holds without threadlocker, so the joint can still be undone for repairs
• Black finish blends in on carbon-fibre frames

Choose the size that matches your screw thread; each pack holds 10 nuts of one size. Tighten until the screw passes fully through the nylon ring with a thread or two showing, as the lock only grips once the screw engages the insert.
