How Does Low Strength Threadlocker Work?
How It Works
Filling gaps in threaded fasteners
Low strength threadlockers fill small spaces between screws and bolts. These tiny gaps can make fasteners loose over time, especially with constant movement. The glue is thin and flows easily into these spaces, creating a strong hold.
This glue improves how fasteners grip by removing empty spaces.
It’s great for screws that need regular fixing or adjusting.
People call them "removable" threadlockers because they’re easy to take apart.
By filling gaps, the glue stops screws from loosening, even in shaky places. This keeps your setup safe and steady.
Stopping tiny movements caused by vibrations
Shaking can make screws move slightly, which loosens them over time. Low strength threadlockers act like a cushion, stopping these movements and keeping screws tight. This also protects the threads from wearing out. You can trust this glue to keep things secure, even with constant shaking.
How It Hardens
Hardening without air
Low strength threadlockers harden when there’s no air. When you put the glue on a screw, it stays liquid until it’s pressed between metal parts. Once air is gone, the glue starts to harden and forms a strong hold.
Anabond 112E | Loctite 271 | |
|---|---|---|
Specific Gravity @ 25°C | 1.0 – 1.1 | 1.1 |
Viscosity @ 25°C (cP) | 500 - 700 | 400 to 600 |
Functional Cure Time (h) | 2 – 10 | 90 minutes |
Full Cure Time (h) | 24 | 24 |
Breakaway Torque (M10 steel) | 40 – 60 N·m (4.0 – 6.0 kgf·m) | 17 to 40 N·m (150 to 350 lb.in.) |
Compressive Shear Strength (N/mm²) | 20 – 30 (200–300) | N/A |
Service Temperature (°C) | -55 to +150 | N/A |
This process makes the glue strong but still easy to remove later.
Things that affect hardening time
Some things can change how fast the glue hardens. Heat makes it harden quicker, while cold slows it down. The type of metal matters too—steel helps it harden faster. To get the best results, clean the surfaces and keep the right temperature.
