Exchange the first bit for the extraction bit in your drill, insert it in the pilot hole, and very gently tap your drill and the bit snuggly into place with a hammer. The extraction bit is also a left-handed drill bit (but with a different purpose), so you’ll continue using the reverse drilling setting.
Check your extraction kit’s table for the right size bit for the bolt size. STEP 3: Switch to an extraction bit.įor a stubbornly entrenched bolt, you’ll need an extraction bit. If the bolt hasn’t loosened at all, proceed to Step 3 for extraction. Remember, “righty-tighty, lefty-loosey”-turn the bolt left (counter-clockwise) to remove it. Hopefully, reverse-drilling your pilot hole will loosen the bolt enough to let you use vise grip pliers to remove the bolt. Now, place the drill bit on the punch mark you made and, holding the drill securely, slowly reverse-drill a small pilot hole in the bolt, about ¼-inch deep. The torque of drilling in reverse (i.e., counter-clockwise) will prevent you from further tightening the threads on the bolt. Set your drill on reverse and as slow a speed as possible (ideally, 20 RPM), and insert the left-handed drill bit.

Pro Tip: If you’re picking up a kit for the job, invest in quality the last thing you need is a cheap bit breaking during this process. This provides a better bite when you use your drill in reverse to remove a fastener. STEP 2: Slowly, use a left-handed drill bit to create a pilot hole.Ĭheck the table on your extraction kit to select the proper-sized left-handed drill bit (also called a “reverse drill bit”) to make a pilot hole in this broken bolt. Unlike traditional drill bits, which are considered right-handed and threaded in a clockwise direction, left-handed bits are designed with a counter-clockwise thread. Furthermore, if the threading on the bolt hole is damaged, you may be unable to use a new bolt once the old one is extracted. If the threads on either the bolt or the bolt hole are damaged, it may make bolt removal impossible. A precise pilot hole is critical to help you to avoid damaging the threads of the broken bolt when you extract it.
Hit it squarely with the hammer to create a starting point for drilling a pilot hole. Place the center punch as close to the middle of the broken bolt as possible.

To secure elevated piping and prevent pipes from moving or hitting each other, a curved bolt that has threads on both ends like the U-bolt might be a product of choice.
These can only be unbolted from one side, adding a layer of safety when fixing or taking structures apart. We also have carriage bolts for applications in woodwork or carpentry. With greater strength, these are often used in repairing and maintaining structures like bridges and buildings.

Fully-threaded bolts are more suited for heavy-duty use since the pressure can be spread among the full length of the bolt itself after installation. There are both partially-threaded and fully-threaded designs. Hex bolts or hex-head bolts, characterized by their six-sided hexagonal heads, are versatile and used in a wide range of applications. They are widely used to secure furniture parts in tables and chairs. They are often used to fix wood and metal structures together as these bolts are usually flat on one end and pointed on the other, with the part designed with closer threads meant to go into metal. Hanger bolts have threads on both ends, and such a double-ended design makes such bolts suitable for use in furniture buildings. The unthreaded cylindrical section in the middle of the shaft allows them to act as pivot points, enabling the rotation of other attached parts. These bolts are essential for putting together moving parts like pulleys and gears. For companies dealing with machinery or maintenance work, products like the shoulder bolt are extremely useful. We offer wholesale remove broken bolt for effective assembly and fastening.
