Stainless Steel Thread Inserts
What are stainless steel thread inserts? Stainless steel thread inserts create durable machine threads in wood, metal, or soft material, or repair stripped threads. Made from stainless, they resist rust and add strong, wear-resistant threads that outlast the base material in wet and outdoor use.
Thread Inserts, Stainless Steel
Helicoil Inserts
Coiled wire inserts that thread into a tapped hole to form a strong, wear-resistant thread or repair a stripped one.
Rivet Nuts
Corrosion-resistant 18-8 stainless threaded inserts set from one side to create a strong machine thread in sheet metal, tube, and panels.

Thread Inserts for Metal
Threaded inserts that create or repair a machine thread in metal parts for a durable, reusable hole.
When a thread insert is the right fix
Thread inserts solve two problems: they add strong, reusable machine threads to soft materials like wood, aluminum, and plastic that would otherwise strip, and they repair holes whose original threads have failed. Helicoil wire inserts are the go-to for high-strength thread repair in metal, while hex-drive and screw-in inserts create fresh threads in wood. In stainless, the insert resists corrosion so the thread stays reliable outdoors, with 316 for coastal exposure.
Why choose stainless steel thread inserts
- Strong reusable threads: hold up to repeated fastening in soft material.
- Thread repair: restore stripped holes to original size.
- Corrosion resistance: keep the thread reliable in wet and outdoor use.
- Range: Helicoil, hex-drive wood inserts, and metal and wood inserts.
Common applications for stainless thread inserts
- Reinforcing threads in wood, aluminum, and plastic
- Repairing stripped threads in metal
- Knock-down furniture and equipment
- Marine and outdoor assemblies (use 316)

Stainless Steel Thread Inserts FAQ
What is a thread insert used for?
To add strong machine threads to soft material or to repair a stripped hole, giving a durable, reusable thread that outlasts the base material.
What is a Helicoil insert?
A coiled wire insert that threads into a tapped hole to form a strong, wear-resistant thread or repair a stripped one, common in metal.
Should I use 18-8 or 316?
18-8 suits most use. For coastal and marine exposure, choose 316 for the best corrosion resistance.
