Precision Hardware SolutionReliable Threads for Wood Mounts

Upgrade your model building project with high-quality Brass Threaded Inserts, designed to provide strong machine threads directly into wooden structures. Ideal for securing engine mounting rails and wing hold downs, these inserts deliver superior holding power. They serve as an efficient, reliable solution when traditional blind nuts are impossible or difficult to fit.

Heavy Duty Wood ThreadingStrong Hardware for Model Aircraft

Engineered for RC aircraft builders and hobby crafts, these Brass Threaded Inserts create durable threaded sockets in wood for smooth assembly and disassembly. Whether you are anchoring RC plane engines to wooden rails or creating strong wing hold down assemblies, these inserts ensure your critical fasteners stay tight under vibration and flight loads. Crafted from solid brass for excellent wear and corrosion resistance, they are the perfect hardware upgrade when tight spaces render standard blind nuts unusable.

Frequently Asked QuestionsEverything you need to know
What are the main applications for these Brass Threaded Inserts?

These Brass Threaded Inserts are primarily used in RC aircraft and wood model building to create machine screw threads in wooden structures, such as engine mounting rails and wing hold down mechanisms.

Why should I use Brass Threaded Inserts instead of standard blind nuts?

Brass Threaded Inserts are ideal for tight or enclosed areas where blind nuts are impossible or difficult to fit behind the wood panel or rail.

How do I install these Brass Threaded Inserts into my RC model's wood mounting rail?

Simply drill an appropriately sized pilot hole into the wood and thread the Brass Threaded Inserts directly into place, creating a solid, permanent machine thread.
