How to Remove a Broken Pipe, Bolt or Stud: A Practical Guide

A pipe nipple that snaps inside a fitting, a bolt that shears off flush, or a stud that is rusted solid can stop a simple repair in its tracks. The good news is that most of these can be removed with the right extractor and a bit of patience. The key is to choose a tool that matches the type of break.

Before you start

• Turn off the water and drain the line if you are working on plumbing.
• Apply penetrating oil to rusted threads and give it time to work, ideally 15 minutes or more.
• Clean the broken end so the extractor can grip properly.
• Wear eye protection. Hardened tools can chip under heavy load.

Broken pipe or faucet nipple

When a threaded pipe breaks inside a fitting, the remaining piece is usually a thin-walled ring. An internal pipe extractor grips the inside of the pipe and lets you unscrew it counterclockwise. Use the broken pipe thread extractor for common 1/2", 3/4" and 1" fittings, or the faucet pipe extractor tool for damaged faucet connections. Turn slowly and steadily; if it does not move, add more penetrating oil rather than more force.

Snapped bolt or screw

For bolts and screws broken flush or below the surface, a screw extractor works by biting into a pilot hole. Drill a small, centered hole first, then drive the extractor in counterclockwise. A broken screw and bolt extractor set lets you pick the size that matches the fastener.

Rounded or seized stud

If part of the stud or bolt head is still sticking out, a socket-style stud extractor grips the outside and works with a ratchet or impact wrench. See the broken stud extractor, 6–13 mm.

When to stop

If the extractor starts to slip, stop and reassess. Forcing it can break the extractor inside the hole, which is much harder to remove. In older plumbing, it may be safer to replace the fitting instead.
