M27*300 PTFE Blue / Dacromet Coated ASTM A320 L7 Fully Threaded Rods

M27x300 ASTM A320 Grade L7 Fully Threaded Rods specifically designed for extreme environments, these rods feature advanced PTFE Blue or Dacromet coatings, offering superior corrosion resistance and chemical stability where standard finishes fail. 
Crafted from high-grade Alloy Steel, they deliver the exceptional tensile strength and low-temperature toughness required by the rigorous L7 specification, making them ideal for oil & gas, petrochemical, and heavy industrial applications.
While the M27x300 model is our featured solution, our manufacturing capabilities are built for total flexibility as your trusted OEM/ODM partner. 
We support a comprehensive range of thread types, from metric (M10–M36) and trapezoidal (Tr) to imperial sizes spanning 3/8" up to 3".
Beyond PTFE and Dacromet, customize your order with diverse surface treatments including Black Oxide, Zinc, Phosphate, or Yellow Zinc to match your specific environmental challenges.
We expand beyond standard Alloy Steel to offer 4140, 4340, 4145, 1045, 40Cr, 45#, 35CrMo, and SS316 Stainless Steel, ensuring the perfect metallurgical match for your project's stress and corrosion requirements.
