CTA Pro-Thread Thread Insert

Stainless steel inserts that help you bring worn threads back to life.

A practical fix for cleaner repairs and a tighter hold.

Product Overview:

When a thread strips out, it throws the whole job sideways. This thread insert gives you a straight path back, without a lot of drama. You get a 10 pack of stainless steel inserts made for 5/16-18 repairs, so you can rebuild damaged holes in cast iron, steel, aluminum, and other metals or plastics. It fits right into the kind of work that comes up on cars, spark plug ports, outdoor power gear, bikes, and farm equipment. Picture the repair settling in clean and solid, with that snug feel you want when you turn the fastener home.

Key Features:

• Repair ready design: Use it with CTA Pro-Thread Kits, and you have a straightforward way to restore worn threads without fuss.
• Stainless steel build: The insert stands up to heat and corrosion, so the repaired thread keeps its shape in rough service.
• 5/16-18 sizing: The thread size matches the job, giving you a clean fit for common repair work.
• Ten inserts per box: You get enough pieces to keep moving through a few fixes, which saves time when work stacks up.
• Wide repair use: It suits automotive jobs, spark plug ports, and outdoor equipment, so one small box covers a fair bit of ground.
