PTFE Coated Fasteners

Teflon Coated Bolts and Nuts/ B7 Studs manufacturer in india guaranteed best price in india

PTFE Coated Fasteners are coated with a synthetic material Polytetrafluoroethylene which is a fluoropolymer. It offers non – stick properties with durability. Viha Steel & Forging is a leading manufacturer of these different types of PTFE Coated Bolts and Nuts in different specifications and standards. The coating allows the fasteners to operate under high temperatures without losing the coat. The PTFE has the highest operating temperatures among fluoroplymers. The PTFE Coated Screws also get much abrasion resistance as the fasteners themselves are consolidated from touching any abrasive surface.

The teflon coated fasteners come under different specifications and types as well. Teflon is another synthetic material used to coat metal material. There are different types and classes such as the square, hex, round, T-head and flat fasteners. The dimensions vary according to the thread configurations. There are B1.13M 6h metric coarse threads and other types. There are also different classes such as the PTFE Coated B7 Studs, The B8, B8M and class1 and 2 in different standards. The torque levels of the fasteners range with different specifications such as the ASTM A193, A1082, A1014 and many others.

The PTFE Coated Stud Bolts are used in applications with narrow spaces that need to connect the components without nuts. The different application types such as high pressure, high temperature, high abrasion resistant, high ductility and others use the different types of fasteners. As a leading manufacturer we supply the PTFE Coated Threaded Rod and others in various dimensions and specifications. Please feel free to contact us for more information on these fasteners and their prices.

Why PTFE Coatings is need to Coat Bolts
  1. Release or retightening of the bolt within the foreseeable future is necessary.
  2. The plain bolts, after stuffing in the holes, are expected to sit out in the weather for an extended period of time and get dried out and rusty, making correct tightening difficult or impossible.
  3. Cleaning and painting of bare steel bolts in the field is likely to be difficult, expensive, and in some cases, not feasible.
  4. Fluoropolymer coatings are extremely durable and not easily removed. However, during assembly of fasteners in the field, the coating can sometimes be damaged. With most other fluoropolymer coatings, this results in exposed bare metal that quickly begins to show corrosion and causes the coating to fail. Our metallic base coat ensures superior corrosion resistance and continues to provide protection even under the harshest conditions.
  5. Due to its unique benefits, Fluoropolymer Coating has been applied to various types and grades of fasteners. The water works industry takes advantage of the superior corrosion resistance properties by coating Hex-head bolts for underground service. Stainless steel fasteners, used in many different industries, are coated for lubricity and anti-galling.
