LOCTITE® 270

Features and Benefits

Threadlocking Adhesive - high strength. Permanent locking. Suitable for all metal threaded assemblies.
LOCTITE® 270 is a high-strength threadlocker for maximum efficacy in the securing and sealing of bolts, nuts and studs to prevent loosening due to vibration. The product serves to permanently lock assemblies which must not come loose. It works on all metals, including passive substrates such as stainless steel, aluminium and plated surfaces. It is proven to be tolerant of minor contamination due to industrial oils, e.g. engine oils, corrosion prevention oils and cutting fluids. Can be disassembled by heating to 300°C.

How to

Step by Step Guide

1. Preparation - Cleaning

It is recommended to use LOCTITE® SF 7063/7064 to degrease and clean surfaces prior to applying adhesive.

2. Preparation - Activation

If cure speed is too slow due to passive metals (stainless steel, aluminium and plated metals) or low temperature (below 5°C), use activator LOCTITE® SF 7240 or LOCTITE® SF 7649 (see cure speed vs activator graph in the TDS).

3. Application

Apply liquid threadlocker to the engagement area. For manual dispensing the use of a peristaltic handgun is recommended to ensure a consistent application volume.

4a. Application - Through Hole

Insert bolt and apply threadlocker to the exposed thread. Assemble nut and tighten to the correct/specified torque.

4b. Application - Blind Hole

Apply into lower third of blind hole.

5. Assembly

Assemble and tighten. If several bolts are being assembled, torque them down to the correct value within the fixture.

6. Disassembly - Hand Tools

Disassemble with standard hand tools.

7a. Disassembly - Heat

If disassembly is not possible using normal hand tools, apply localised heat to approximately 250°C. Disassemble while hot.

7b. Disassembly After Heating - Hand Tools

Disassemble while hot with standard hand tools.

Hint

For the disassembly of corroded or seized parts, use LOCTITE® LB 8040 Freeze and Release.
