The built-in flange acts as an integral washer to distribute clamping load and simplify installation, while the 12-point external drive supports high-torque engagement in tight or awkward spaces without slippage. Manufactured from alloy steel and cadmium-plated for corrosion resistance, this nut carries a dry-film lubrication that minimizes friction and galling across multiple tightening cycles and helps maintain consistent torque values. The prevailing-torque locking action resists loosening under vibration, making it a suitable choice for aerospace, defense, and industrial equipment that operate in demanding environments. In systems that follow similar dry-film-lubed, self-locking flange-nut specs, the rated operating temperature is around 450°F (232°C), enabling use in high-temperature applications without compromising lock integrity. Use with standard 1\/2-inch bolts to achieve secure fastening where a flange provides added stability and a low-profile, easy-to-install locking solution.\u003c\/p\u003e\u003c\/div\u003e","brand":"ALCOA","offers":[{"title":"New","offer_id":51657194668334,"sku":null,"price":158.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_0cfec563-b2d2-4bb6-b55c-59b74da626e1.jpg?v=1769466745","url":"https:\/\/plgautomation.com\/products\/industrial-1-2-20-12-point-self-locking-flange-nut-dry-film-lubricated-500f-flange-nut","provider":"PLG Automation ","version":"1.0","type":"link"}
