## Description

Some items need a completely customized fixture for safe and secure workholding. Thermo-Loc softens with heat to a pliable clay-like consistency that you can form around your work. At room temperature, it hardens and securely holds nearly anything from firearm parts to jewelry. Thermo-Loc is easy to use. Just follow these basic steps: heat, form, and hold.

## Features

- Thermo-Loc is a special reusable polymer material that is rigid at room temperature yet becomes pliable when heated or warmed. Developed to hold irregularly shaped or fragile items, Thermo-Loc can be used on firearms, knives, wood, and more. Supplied in convenient 6" (150mm) long sticks, Thermo-Loc is a medium gray color designed to reduce eye strain under work lights.
- Under extreme heat may cause sticks to burn.

### ⭐⭐⭐⭐⭐ 







  
  
    Works Great
  

*by A***S on Reviewed in the United States 🇺🇸 on February 2, 2021*

Microwaved as advised to mold together several rods and create basic shapes to hold in my ring holder and also vice.  Then I use a heat gun to just soften the top enough to insert the thing I want to hold and gently push the thermolock just over the edge so when it hardens up the thing is held securely.  Works great!

    A must have for jewellers
  

*by Y***A on Reviewed in the United States 🇺🇸 on August 17, 2018*

So glad I found this reasonably priced and perfectly proportioned amount of thermo lock!I do not need the full set sold from my suppliers, as this stuff is quite reusable, and my work does not require large amounts at a time.  However, 1/4 lb is still plenty.  Very happy with this purchase.  And for those wondering if you will need the silicon/teflon mat thing that comes with the original package, it's not necessary.  I did order some non-stick teflon craft sheet and so far have not needed it.  But again, I work with small rings etc, if you are using this to engrave guns/knives etc then you might want to get yourself some of this to go along with your thermo lock. . https://www.amazon.com/dp/B00HX5TDP8/ref=cm_sw_r_sms_awdb_t1_JpXDBbMADYGWX

    Disappointing. Photo not accurate for what was received.
  

*by V***H on Reviewed in the United States 🇺🇸 on April 20, 2020*

The photo is deceiving. The bag I got was less than half that size. How are you supposed to know how much 1/4 lb is.Also did not come with instructions.Very disappointed.
