They have serrations that grip the material surface instead of threads for easy installation and mild vibration resistance. They are commonly used in assembly lines where operations are speeded by using a single fastener instead of a nut and a washer. The high quality 304 stainless steel provide perfect strength and good corrosion resistance in bad environments like high temperature, cold weather and high humidity areas without the need for time consuming and costly maintenance.

Review: Very good nuts, they worked perfectly for my car. - I own a 2013 Mercedes S550 Base W221, and I had to remove the tail lights to replace the light bulbs inside. I never thought that these tail lights would use such small-sized nuts to hold them in place. It takes 3 of them per side, so when I went to install them back, I lost 2 of the nuts. I came to desertcart looking for replacements, and this pack popped up when I entered the description, M5x0.8mm. I ended up buying 100 nuts for the price of a single Mercedes Benz branded one, and these are better than the OEM ones. I can't recommend these enough! Review: WORKS - GOOD ITEM ## Features - PRECISION M6-1.0 SPECS: - Thread: M6-1.0 Metric - Type: Serrated Flange Nut - Standard: DIN 6923; Built for versatile, medium-duty fastening where a high-torque, non-slip connection is critical. - CORROSION-PROOF 304 STEEL: Forged from premium 18-8 (304) Stainless Steel for superior rust and oxidation resistance.
