Blue Medium Strength Threadlocker
Product category: Threadlockers
- Technical specifications
LOCTITE® 248 is a general purpose threadlocker with medium bond strength. This product is available in a convenient stick format. This threadlocker secures and seals bolts, nuts and studs to prevent loosening due to vibration. The product works on all metals, including passive substrates such as stainless steel, aluminum and plated surfaces. It is proven to be tolerant of minor contamination due to industrial oils, e.g. motor oils, corrosion prevention oils and cutting fluids.

How to use
It is recommended to use LOCTITE® SF 7070™ to degrease and clean surfaces prior to applying threadlocker.
If cure speed is too slow due to passive metals (stainless steel, aluminum and plated metals) or low temperature (below 5°C), use LOCTITE® SF 7649™ activator. Allow to dry.
Apply a 360 degree band of threadlocker to the male fastener at the area of engagement and completely fill the thread roots - generally the width of 2-3 threads. Assemble nut and tighten to proper torque.
Apply threadlocker to entire diameter of thread engagement area on male fastener, install fastener into blind hole, and tighten to proper torque.
Assemble and tighten to proper torque requirement. If several bolts are being assembled, torque them down to the correct value within the fixture time window.
Disassemble with standard hand tools. If not possible, apply localized heat to approximately 500°F/260°C and disassemble while hot.
Prevent vibration loosening, prevent leaks, protect threaded components from corrosion and increase the reliability of mechanical fasteners by using a LOCTITE® anaerobic threadlocking adhesive.
The standard continuous operating temperature range for LOCTITE® anaerobic adhesives is -65°F to +300°F (-55˚C to +150˚C).Depending on the specific application requirements, high-performance grades are also available offering increased temperature resistance. Please consult with the Henkel technical team for availability and grade selection.
Yes, LOCTITE® threadlockers become highly resistant thermoset polymers once cured, making them suitable for a vast number of applications. Consult Henkel's online product Technical Data Sheets (TDS) and other product resources, or contact our technical teams for further information.
Yes, these products are all anaerobic adhesives that will function in a similar way. Variations in the adhesive characteristics (viscosity, gap-fill, strength, etc.) will make them better suited to certain applications. Consult the product technical data sheets and/or Henkel representatives for further information.
All necessary H&S measures and PPE (personal protection equipment) requirements can be found on the product material safety data sheet, all of which are available via our website.
