Internal Tooth Lock Washer for nut or threaded rod M10x1 – zinc plated

A lock washer (also known as a star washer) is used to tighten bolts, nuts, and screws securely. This washer ensures that they do not vibrate loose. Internal tooth lock washers are serrated rings that create extra friction and grip under a nut, making it difficult for it to unscrew.

Why teeth on the inside? On this lock washer, the teeth face inwards. While there are also washers with teeth on the outside, this internal version is much smarter for lamps:

• Better result: The teeth are hidden under the nut. This means they are not visible, providing a much neater finish.

• No scratches: The teeth won’t scratch the visible parts of your lamp, only the area that remains hidden anyway.

• Extra grip: It grips the nut exactly where the most pressure is applied.

Features of the internal tooth lock washer:

• Stays secure: The teeth prevent the nut from vibrating loose. Your lamp will always remain sturdy and stable.

• Easy to use: Simply slide the washer over the thread (M10) before screwing on the nut.

• Rust-proof: The washer is zinc-plated, so it stays looking good and remains strong for a long time.

• Size: Fits perfectly on M10 threaded rods (the standard size for most lamps).

• Dimensions: It is 18 mm wide and 3 mm high.
