M6 Serrated Flange Hex Lock Nuts Bright Finish?304 Stainless Steel 18-8 Pack of 50

Package Included: M6 Flange Hex Nuts x 50 PCS About Serrated Flange Hex Nut Flange nuts have a washer-like base to distribute pressure over a greater surface area and ensure the fastener stay tight. 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.
