C&N offers a wide variety of PTFE fasteners. Regardless weather you want a xylan 1424 blue A193 B7 stud bolts (we consider very standard), or xylan black B-16 hex bolts, we are experts at PTFE coated fasteners. We are capable of providing a full gambit of colors and products. We stock many different sizes of xylan coated studs and xylan coated hex bolts, but also have the F-436 flat washers PTFE ready to ship as well… Other stock items already coated include:
Many of our PTFE fasteners are coated with a proprietary Flurokote#1 blend that offers superior characteristics for maximizing the life of fasteners. This PTFE coating include a tensile strength of up to 4,000 psi & an operating pressure up to 100,000psi. Unlike hot dip galvanized fasteners, the absence of oxides promise a safe and easy removal of "frozen nuts"when using xylan coated fasteners from Lightning Bolt.
PTFE is extensively used as a coating for Fasteners used in Oil & Gas, Marine & Offshore applications. PTFE coated fasteners stands exceptional to Salt Spray Test. It has outstanding release capabilities and can withstand a maximum use temperature of 600°F, higher than any fluoropolymer. This coating is typically applied to a thickness of 1-3 mils. Ptfe is also commonly referred by their tradename/brands, tef-lon, xylan, etc. These fluoro poly makes excellent choice for agressive environment. Ptfe or tef-lon coated fasteners are widely used in onshore and offshore engineering applications.
Below is several advantages of coating with PTFE fasteners. FluoroKote#1® possesses a low coefficient of friction which reduces torque requirements. Therefore there is an easy on/easy off properties exhibited by these fasteners provide safe removal with wrenches. Lower your plant maintenance cost and increase safety by using Tef-lo-n™ fasteners. Sometimes refereed to as xylan coated fasteners, this fluropolymer coating offers a 2200 hour resistance to corrosion. Tef-lo-n™ fasteners are viewed by many engineers as a cost effective method of keeping corrosion under control, while not substituting for weaker alloys such as stainless steel.
