This guide, presented by Dave Timm, details the proper application and selection of threadlockers for firearm components. It emphasizes the importance of degreasing for optimal bonding and outlines the use of different strength threadlockers, from low-strength purple for small screws to high-heat red and industrial-strength Rocksett for critical applications like muzzle devices and gas blocks. Proper curing times and torque specifications are also highlighted for reliable component retention.

Quick Summary

For firearm applications, threadlockers are categorized by strength: low (purple) for small screws, medium (blue) for general accessories like optics, and high (red) for heat-exposed parts like gas blocks. Proper degreasing with denatured alcohol is vital for a strong bond. High-strength red threadlocker requires heat for removal.

Frequently Asked Questions

What are the main types of threadlocker for firearms and their general uses?

Firearm threadlockers come in low (purple), medium (blue), and high (red) strengths. Low strength is for very small screws, medium for general accessories like optics and mounts, and high strength for components exposed to significant heat or vibration, such as gas blocks.

Why is degreasing essential before applying threadlocker to firearm parts?

Degreasing with a solvent like denatured alcohol is crucial to remove oils and contaminants from threads. This ensures proper adhesion of the threadlocker, creating a strong, reliable bond that prevents parts from loosening due to vibration or stress.

How do you remove high-strength red threadlocker from firearm components?

High-strength red threadlocker requires heat for removal. Applying heat from a small torch or pencil soldering iron to the fastener will break the bond, allowing it to be loosened with tools. Be cautious not to overheat the firearm components.

What is Rocksett and when should it be used on a firearm?

Rocksett is an industrial-grade, clear adhesive with very high heat tolerance, ideal for securing muzzle devices, especially suppressor mounts, to barrels. It's water-soluble and removed with boiling water and shock.
