Uncompromising Security for Critical Assemblies: Introducing Loctite 263 High Strength Threadlocker

When your applications demand an unyielding, permanent hold, turn to the Loctite 263 High Strength Threadlocking Adhesive (50 ml) , available now at 3FPARTS.COM. This iconic red threadlocker is engineered for the most demanding environments, providing high-strength, permanent locking and sealing of threaded fasteners up to M25.

Loctite 263 is a premium, primerless anaerobic adhesive designed to prevent loosening due to severe shock and vibration. It excels on all metals , including passive substrates like stainless steel, aluminum, and plated surfaces, offering superior versatility. A key advantage for industrial settings: it's suitable for use on most oil-coated, "as-received" fasteners, often eliminating the need for time-consuming pre-cleaning.

How it Works: This advanced liquid compound effectively fills all microscopic voids between engaged threads, curing into a rigid thermoset polymer. This process not only permanently locks the fastener but also significantly increases breakaway torque (up to 40%!), reinforcing the overall joint stability and creating a reliable seal against leakage.

Key Features & Benefits You'll Value:

• Permanent, High-Strength Bond: Formulated for applications where fasteners must remain securely in place, Loctite 263 creates an exceptionally strong, permanent bond that reliably prevents loosening from vibration and shock in heavy-duty applications like studs in motor housings.
• Removable with Heat: While providing a permanent lock, this adhesive allows for disassembly when necessary by applying localized heat (typically 182°C / 360°F), making repairs and maintenance possible.
• Reliable Thread Locking and Sealing Performance: Engineered to resist loosening and leakage caused by shock and vibration, ensuring long-term integrity of your assemblies.
• Compatible with All Metals: Performs effectively on a wide range of metal surfaces, including active metals and inactive (passive) substrates like stainless steel and plated components, without the need for a primer.
• Oil-Tolerant: Can be used on most oil-coated, 'as-received' fasteners without prior cleaning, streamlining your assembly process.
• High Temperature Performance: Maintains its integrity and strength in environments up to 182°C (360°F), making it suitable for applications exposed to elevated temperatures.
• Fast Fixture Time: Achieves initial strength quickly in just 10 minutes, allowing for faster handling of components.
• UV-Detectable for Easy Inspection: Distinguished by its vibrant red color and fluorescent properties, Loctite 263 glows brightly under UV light, making it simple to confirm proper application during quality checks or routine maintenance.
• Optimal Viscosity: With a viscosity of 400 to 600 cP, it flows well into threads while staying where applied.
• Convenient 50 ml Bottle: Provides an ample quantity for numerous critical applications, offering excellent value.
• Product Code: 1367281

Ideal for: Heavy-duty applications requiring a permanent, high-strength lock, such as:

• Studs into motor housings
• Large bolts and nuts on presses, pumps, and other machinery
• Any critical fastener where ultimate security is paramount.
