Apply threadlocker to keep vital fasteners in place. How does threadlocker work? It bonds the threads to prevent slippage. Details here.
How does threadlocker work? This amazing adhesive is an essential tool for mechanics and DIYers. We will show you when and how to use this product!
Threadlocker is an adhesive specially formulated to keep nuts, bolts, and screws from loosening due to vibration, stress, and normal use. It is applied to the threads of a bolt as it is inserted and screwed into place.
Threadlocker bonds the fastener together so that it will not loosen on its own, yet it can still be removed when necessary. By coating and protecting the threads, threadlocker also prevents rust and corrosion which weaken the fastener and may make removal difficult.
It is important to note a general-duty threadlocker can be detached with common hand tools. Stronger formulas will require heating up the nut and bolt with a torch or flame before removal of the bolt is possible.
Threadlockers are available in a variety of strengths to suit different applications. This is often indicated by a colour and number (higher number for higher strength) in the product name.
How much threadlocker do you need to apply? Just follow these simple guidelines:
- Clean the threads of the fastener to be installed. Ensure there is no dirt, grit, or oil present.
- Shake the bottle of threadlocker.
- Apply a few drops of threadlocker.
For through holes: Add several drops for even coating to the threads of the bolt. Use a brush to spread product evenly.
For blind holes: Coat the threads as above, but also apply product to the internal threads to ensure the bottom of the hole is lightly coated as well.
For sealing purposes: Leaving the first thread of the bolt untouched, apply the threadlocker around the bolt in a circular motion to form a ring, ensuring the product fills all the thread voids. For a heavy-duty job, in addition to the bolt, apply a second ring of product to the hole threads as well. - Assemble the parts and tighten the fastener.
- Allow the threadlocker to cure before normal use of the item. This will be indicated on the product packaging.
Use threadlocker any time you want to keep a screw or bolt from loosening or corroding. Just select the appropriate formulation for the job and follow the directions above.
It is especially important to apply threadlocker to crucial fasteners on engines, motors, and any mechanical devices which experience vibration or temperature extremes. This will prevent leaks, breakdowns, and potential accidents.
