Bostik NSN-160 (1-lb-Tin)

NEVER-SEEZ® Regular Grade Anti-Seize & Lubricating Compound

Overview

NEVER-SEEZ® Regular Grade is a premium anti-seize and extreme-pressure lubricating compound developed by Bostik for protecting threaded fasteners and mating components against seizure, corrosion and galling. Formulated with copper, graphite and metallic particles suspended in a high-quality grease, it provides reliable lubrication under high temperatures, heavy loads and corrosive environments. The compound simplifies maintenance by allowing easier disassembly after prolonged service and is widely used across aerospace, industrial and heavy equipment applications.

Key Features & Benefits

• Protects against seizure, rust and corrosion.
• Minimises galling on stainless steel, titanium, magnesium and similar metals.
• Facilitates easier disassembly after prolonged high-temperature service.
• Resists carbon fusion and corrosion caused by alkalis, acids, vapours, road salt, steam and salt water.
• Reduces wear and extends component service life.
• Improves clamping force at the same tightening torque.
• Suitable for high-pressure and high-temperature applications.
• Provides excellent extreme-pressure lubrication.

Application Guidelines

• Apply a thin, even coating to clean threads and mating surfaces before assembly.
• Use only the amount necessary to achieve full thread coverage.
• Account for the reduced torque coefficient when tightening fasteners.
• Follow OEM torque specifications where anti-seize compounds are permitted.
• Keep the container tightly sealed to prevent contamination.

Compatibility & Limitations

• Suitable for carbon steel, stainless steel, titanium, magnesium and many other metals.
• Not recommended for high-speed bearings; use Never-Seez® Red Bearing Lubricant instead.
• Where copper is prohibited, use Never-Seez® Nickel Grade, Nuclear Grade or Never-Seez® Blue Moly.
• Verify compatibility with aircraft maintenance manuals before aerospace use.

Why This Product is Chosen for AOG / MRO

• Prevents seized fasteners during aircraft maintenance.
• Supports easier component removal after long service intervals.
• Performs across an exceptionally wide temperature range.
• Protects threaded hardware exposed to harsh environmental conditions.
• Compatible with many aerospace and industrial maintenance tasks.

Practical Suggestions for Your Team (AOG Mindset)

• Reduce tightening torque where specified because the lubricant lowers friction.
• Do not use on applications where copper-containing products are prohibited.
• Apply only to clean threads for maximum protection.
• Store below 49°C to maximise shelf life.
• Always verify aircraft maintenance manual approval before use on flight hardware.
