Review: Great product and an excellent value - Great product that is indistinguishable from the brand name stuff. You get a huge quantity by comparison for a much better price. Used it for screws on red dot optic mounts and nothing has worked loose after being used in service.
Review: Great value and works excellent - This stuff is fantastic, save your money on threadlocker and go with this brand.

## Features

- Ideal glue for the installation of smooth/unthreaded cylindrical metal assemblies: 1,Fill the voids and reduce the precision requirements of design, production and installation; 2,Prevent assembly from loosening, wear and corrosion; 3,Evenly distribute loads and stresses during assembly; 4,Sealed from oxygen and other contaminants. Extend the life and safe use of the equipment!
- High Strength: After complete curing, Shear strength can be comparable to that of metal materials (609 ≈ Aluminum, 620 & 680 ≈ Copper, 603 & 638 ≈ %0.1 C Steel, 648 ≈ %0.2 C Steel), Ensuring efficient and stable operation of the equipment. Needs to be heated to 250 ℃/482℉ when disassembling, and mechanical auxiliary equipment is required.
- Applicable Scope: Suitable for the assembly of any smooth, unthreaded cylindrical metal components, Such as keys and shafts, bearing, rotor shaft, bushing, casing, cylinder liner, key slot, valve sleeve, movement sleeve, valve bushing etc. Choose the appropriate use according to the characteristics of different models.
- Applicable Material: Suitable for all kinds of solid metals, even metals with active surfaces such as iron, copper, brass, steel, etc. not to mention metals with inert surfaces such as stainless steel, aluminum, gold, etc.
- Simple Use: Just apply the product evenly to the fixed location, the product will start curing within 60 minutes after the assembly is installed, and it can be used normally after 24 hours of standing.
- Function: Fill gaps between components / Lock components to prevent loosening / Prevent component abrasion & corrosion / Improve the accuracy of component fit / Isolate oxygen and prolong product life / Tightness to prevent leakage / Evenly distribute loads and stresses / Repair minor defects in parts / Reduce design and process complexity

## Questions & Answers

**Q: How do I open and close the bottle?**
A: Dear customer, thank you for your question, you only need to forcefully pull the white bottle cap to open the bottle, the white bottle cap has no screws, so turning it to open is ineffective.

**Q: Good for sticking the otter ring/pulley back onto harmonic balancer?**
A: I believe you meant the outer ring or pulley ring that the serpentine belt rides on.  It's not typically used for applications where torque or radial forces are applied.  It's used most often for cylinder sleeve installation or other sleeve type applications or when one needs a thread lock that is beyond red level thread lock.  I've seen repairs for the outer ring on harmonic balancers being made with epoxy like binary adhesion compounds, i.e. JB Weld

**Q: What is required to disassemble the parts? Is heat required?**
A: Dear customer, thanks for the question, When dismantling, it can cooperate with mechanical auxiliary equipment and heat the components to 200~300°C (392~572°F), or it can be dismantled after soaking with special scavenger for a long time

**Q: Can this be used inside an automatic transmission on pressed in bushings?**
A: Will definitely help retain them in place. Get the primer to speed up the cure time.

### ⭐⭐⭐⭐⭐ Great product and an excellent value
*by J***C on March 10, 2026*

Great product that is indistinguishable from the brand name stuff. You get a huge quantity by comparison for a much better price. Used it for screws on red dot optic mounts and nothing has worked loose after being used in service.

### ⭐⭐⭐⭐⭐ Great value and works excellent

This stuff is fantastic, save your money on threadlocker and go with this brand.

### ⭐⭐⭐⭐⭐ Maybe not for Space-X use, but works for me fine.
*by G***H on February 6, 2026*

I always have a bottle of 243 and 680 on hand and use them all the time on all sorts of stuff that needs attention. Yes, the bottle is supposed to be "half full" , the air space is to prevent it from hardening in the bottle. It is sold by weight, not volume and hardens in the absence of oxygen. The application nozzle is opened by pulling up on the white ring at the base, and useful for preventing accidental spills. Not much fun finding the tipped over bottle somewhere with half the liquid hardened underneath it IFYKYK.... Slightly more viscous than the name brand which I think is nice, so I get a better chance of installing the fastener in difficult locations without it dripping off. Works the same, looks the same, smells the same, and hardens the same, at a fraction of the cost.
