Stainless Steel Hex Screw and Nut Kits for Pipe Flanges
Stainless Steel with Blue PTFE-Coated Nuts
Use these kits to connect standard-size stainless steel pipe flanges for ANSI Class 150 or 300. They meet ASTM specifications for material quality, and the dimensions meet ASME specifications. Length of screws is measured from under the head.
316 stainless steel kits are more corrosion resistant than 18-8 stainless steel and have excellent resistance to chemicals and salt water. They may be mildly magnetic. Some kits have blue PTFE-coated nuts. This coating is slippery, chemical-resistant, and prevents galling. It also helps nuts thread smoothly.

Medium-Strength Steel Threaded Rods—Grade B7
These Grade B7 threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.
Blue PTFE-coated steel threaded rods are chemical resistant and have a slippery surface to thread on smoothly.
