Product Description

A193 B7/A320 L7 Fully Threaded Studs with Corrosion Resistance PTFE Coating

Our premium fastener assemblies combine high-performance A193 B7 or A320 L7 fully threaded studs with heavy hex nuts, all featuring a specialized PTFE (Polytetrafluoroethylene) coating for superior corrosion protection. These complete fastening solutions are engineered for demanding industrial environments where reliability, strength, and resistance to harsh conditions are critical. Manufactured from high-grade alloy steels, these stud and nut assemblies undergo precision processing to ensure consistent performance, while the PTFE coating adds an extra layer of defense against corrosion, chemicals, and extreme temperatures. This combination creates a fastening system designed to maintain integrity in the most challenging applications.

Product Features

• Dual Material Options: Available in A193 B7 and A320 L7 alloy steels, both offering exceptional tensile strength and durability

• Complete Assembly: Includes fully threaded studs paired with heavy hex nuts for immediate installation

• Superior PTFE Coating:

Provides excellent corrosion resistance in aggressive environments

Offers low friction properties for easier installation and removal

Resists chemical attack from acids, bases, and solvents

Withstands extreme temperatures ranging from -200°C to +260°C (-328°F to +500°F)

• Heavy-Duty Design: Heavy hex nuts provide increased torque capacity and wrenching surface

• Full Thread Configuration: Ensures uniform clamping force distribution and maximum grip

• Industry Compliance: Manufactured to meet relevant ASTM standards for consistent quality and performance

• Versatile Sizing: Available in various diameters and lengths to suit specific application requirements

Product Applications

Perfect for demanding industrial environments including:

• Oil and gas exploration and production facilities

• Chemical processing plants and refineries

• Power generation (nuclear, fossil fuel, and renewable energy)

• Petrochemical installations • High-pressure piping systems and pressure vessels

• Boiler and heat exchanger assemblies

• Offshore and marine applications

• Pharmaceutical and food processing equipment

• Industrial machinery operating in corrosive environments

These PTFE-coated fastener assemblies deliver reliable performance in critical systems where resistance to corrosion, chemicals, and extreme temperatures is essential for operational safety and longevity.
