LOCTITE® 263 High Strength Threadlocker – 50ml | High Strength | Oil Tolerant | Red | 263-50

High-Strength Threadlocking Adhesive for Permanent Locking and Sealing of Metal Fasteners

Supply Solutions Group supplies LOCTITE® 263 High Strength Threadlocker (Product Code 263-50) to organisations operating across mining, manufacturing, automotive, engineering, construction, transport, heavy equipment, maintenance and industrial workplaces throughout Australia.

Manufactured by Henkel, LOCTITE® 263 is a high-strength anaerobic threadlocking adhesive designed for the permanent locking and sealing of threaded metal fasteners. Supplied in a 50ml bottle, it is particularly suited to applications where excellent resistance to vibration, shock and loosening is required.

LOCTITE 263 is formulated with enhanced oil tolerance, allowing it to perform effectively on fasteners that may have minor contamination from industrial oils. The product cures when confined in the absence of air between close-fitting metal surfaces, forming a tough thermoset plastic that helps prevent unwanted movement, loosening and leakage.

Its high-strength red formulation makes LOCTITE 263 ideal for studs, bolts, nuts and other threaded assemblies that are not intended for frequent disassembly. It can be used on active metals such as steel and brass as well as passive substrates including stainless steel and plated surfaces.

With excellent chemical and temperature resistance, LOCTITE 263 is a dependable threadlocking solution for demanding machinery, plant maintenance and mechanical assembly applications.

As an Indigenous-owned industrial supplier and procurement partner, Supply Solutions Group provides genuine LOCTITE® adhesives, sealants and maintenance products backed by responsive customer service, procurement support and Australia-wide delivery.

Why Choose LOCTITE® 263 High Strength Threadlocker?

LOCTITE 263 provides a reliable solution for threaded fasteners that require a strong, long-lasting lock. Once cured, it fills the microscopic spaces between mating threads to create a durable bond that resists vibration, shock and loosening.

Its improved oil tolerance is particularly valuable in maintenance environments where completely oil-free fasteners can be difficult to achieve. The high-temperature capability also makes it suitable for demanding mechanical and industrial equipment.

Because LOCTITE 263 is a high-strength threadlocker, it is best suited to assemblies intended to remain securely locked rather than components requiring routine adjustment or disassembly.
