LOCTITE® 243 Medium Strength Threadlocker – 10ml | Oil Tolerant | Removable with Hand Tools | 243-10

Professional Medium Strength Threadlocker for Securing and Sealing Threaded Fasteners

Supply Solutions Group supplies LOCTITE® 243 Medium Strength Threadlocker (Product Code 243-10) to organisations operating across mining, automotive, manufacturing, engineering, construction, transport, agriculture, utilities and industrial maintenance throughout Australia.

LOCTITE® 243 is a general-purpose, medium-strength anaerobic threadlocking adhesive designed to secure and seal threaded fasteners against loosening caused by vibration and shock. Supplied in a compact 10ml bottle, it is ideal for maintenance workshops, field service vehicles, toolboxes and industrial repair applications where controlled dispensing and dependable fastening performance are required.

The advanced formulation cures when confined in the absence of air between close-fitting metal surfaces, forming a tough thermoset plastic that locks the threaded assembly in place. Its medium-strength formulation provides reliable retention while still allowing components to be dismantled using standard hand tools when servicing or maintenance is required.

LOCTITE 243 offers improved oil tolerance, allowing effective performance on many fasteners that may have minor contamination from industrial oils. It is suitable for use on a wide range of active and passive metals, including steel, stainless steel and plated surfaces, making it a versatile choice for industrial maintenance and mechanical assembly.

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