PTFE Hexagon Bolt | Chemical Resistant Fluoropolymer Fasteners

PTFE Hexagon Bolts, also referred to as PTFE hex bolts or fluoropolymer hex fasteners, are precision-engineered fasteners manufactured from polytetrafluoroethylene (PTFE). Featuring a standard hexagonal head design for easy tightening and removal, these bolts combine exceptional chemical resistance, non-conductivity, lightweight properties, and durability.

Unlike conventional stainless steel or alloy fasteners, PTFE hex bolts will not corrode, seize, or contaminate sensitive systems, making them an ideal choice for industries that require reliability under extreme chemical, thermal, and environmental conditions.

Key Advantages of PTFE Hexagon Bolts

• Outstanding Chemical Resistance – Unaffected by acids, bases, solvents, and corrosive agents.
• Wide Temperature Range – Reliable performance from -200°C to +250°C.
• Low-Friction, Non-Stick Surface – Easy installation and removal without galling or seizing.
• Electrical Insulation – 100% non-conductive, ideal for electronic and semiconductor applications.
• Lightweight & Non-Magnetic – Safer and easier to handle compared to metal fasteners.
• UV & Weather Resistant – Suitable for outdoor and long-term applications.
• FDA Compliant & Biocompatible – Safe for medical, food, and pharmaceutical equipment.

Common Applications of PTFE Hexagon Bolts

PTFE Hexagon Bolts are widely used in critical industries where traditional metallic fasteners are unsuitable:

• Chemical Processing Plants – Pumps, pipelines, reactors, and storage tanks.
• Semiconductor & Electronics Industry – Non-conductive fastening in cleanrooms and electronic assemblies.
• Medical & Pharmaceutical – Sterile and non-reactive bolts for sensitive devices and production systems.
• Food & Beverage Industry – Hygienic, non-stick fasteners for machinery and processing equipment.
• Marine & Offshore Engineering – Saltwater-resistant bolts for ships, desalination units, and offshore rigs.
• Laboratory & High-Purity Environments – Equipment requiring non-metallic, contamination-free fastening.
