Rotate these dies around studs and rods to create new fastener threads. A cut above lower-quality dies that can leave inferior threads, these are machined in the U.S. to precise dimensions for accuracy and consistency.

They are adjustable, so you can cut a shallow thread that makes it easier to get the die started on the first pass. Turn the set screw to open the die to its largest diameter. Then rotate the die with a round die wrench and adjust the screw as you make additional passes to reach the proper thread size.

Uncoated High-Speed Steel—The most versatile dies stay sharp and cut cleanly, even if you use them every day. They last much longer than carbon steel dies and you won’t have to work as hard to create threads.

Titanium Nitride (TiN)-Coated High-Speed Steel—When you regularly work on challenging metals like stainless steel, choose dies with a TiN coating that reduces friction and resists heat. They turn faster and last longer than uncoated dies.

Make your own threads instead of searching for left-hand fasteners, which can be expensive and hard to find.

Rescue mangled threads and return them to like-new condition. By repairing threads, you don’t have to replace the fastener or resize holes. These dies smooth out flaws and remove rust so threads engage properly and connections stay strong. Turn them with a hex die wrench or a standard adjustable wrench.

Don’t risk damaging threads further with an inferior-quality die. Our dies are machined in the U.S. to precise dimensions for a perfect thread profile.

Uncoated Carbon Steel—Hard and wear resistant for a long life, these dies work well on both metal and plastic.

Repair instead of replacing left-hand fasteners, which can be expensive and hard to find. These dies correct flaws and clean out rust so the threads engage properly. Don’t risk damaging threads further with an inferior quality die. Our dies are machined in the U.S. to precise dimensions for a perfect thread profile. Turn them with a hex die wrench or a standard adjustable wrench.

Uncoated Carbon Steel—Hard and wear resistant for a long life, these dies work well on both metal and plastic.

If your wrench can turn a hex nut, it can turn these dies. They match the width of nuts of the same thread size, so you only need one tool to remove the nut, repair threads on the fastener, and put the nut back on. When space is tight, use dies with a ratcheting wrench since it requires minimal clearance to turn. Repairing dies remove imperfections and rust, resulting in threads that engage properly for a strong connection.

Clamp the two halves of these dies around your bolt, stud, or rod to repair threads anywhere along the length. Since you don't have to spin them into place, they're often used on extra-long fasteners or when you can't access the end of your workpiece. Dies smooth damage, sharpen worn edges, and clean out rust so connections stay secure. Once in position, turn them with a hex die wrench or a standard adjustable wrench.

Black-Oxide Tool Steel—Hard and wear resistant for long life, these dies work well on both metal and plastic.

Be ready for repairs by keeping a range of die sizes on hand. These dies smooth out flaws and remove dirt and rust so threads make strong connections. Don’t risk damaging threads further with an inferior quality die. Our dies are machined in the U.S. to precise dimensions for a perfect thread profile. Turn with a hex die wrench or a standard adjustable wrench.

Uncoated Carbon Steel—Hard and wear resistant for a long life, these dies work well on both metal and plastic.

The dies in these sets match the width of hex nuts that are the same thread size, so one tool can turn both. For tight spaces, use with a ratcheting wrench since it requires minimal clearance to turn. Repairing dies remove imperfections and rust so threads engage properly for a strong connection.

Cut and repair threads and drill holes in many different sizes. Tap and die wrenches are included. The dies are hex shaped for use with conventional wrenches. The taps are made of carbon steel and are recommended for thread repair and occasional tapping.

Taper Chamfer—Taper chamfer taps have 7-10 chamfered threads at the tip for cutting into the workpiece. They require less torque than other chamfer types, making them a good choice for starting threads and tapping through holes. However, a longer taper means that they cannot thread as close to the bottom of closed-end holes.

Plug Chamfer—Plug chamfer taps are a versatile choice for most tapping applications. With 3-5 chamfered cutting threads, they require moderate torque and are often used for start-to-finish tapping of through holes and closed-end holes. However, they do not start threads as easily as taper chamfers. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.
