It works on both regular and tamper-resistant heads, including those screws and bolts damaged by rust.
Elastomer ergonomic hand grips make using this tool easier, while the overall design can fit into tight spaces. The serrated grip makes this tool an excellent choice for broken bolt shafts as well as any damaged screw you run across.

This issue might be caused by receiving a knockoff product as copycats are known to target popular tools. As long as you purchase from a reputable seller, you shouldn’t have to worry about that.

Owners of this tool frequently tell stories of how the 70016 easily defeated difficult studs and damaged bolts. They note that the design allows it to grab studs with smaller degrees of exposed metal the smaller the stud size.
While its thickness may restrict your usage in tight spaces, long-time owners point to the durability and long lifespan as a fair trade-off.
Most issues regarding the Ares bolt extractor are size-related. The body is beefy, making it difficult to fit in some tight spaces. Additionally, some bolt heads will be too big to fit the tool over.
It should also be noted that while the extractor can grip 1/4 inch studs, it will not grip 6mm studs, as the 1/4 inches is equal to 6-1/3 mm.

An extractor is an odd-looking tool that grips onto broken bolts and screws, allowing you to safely remove them with minimal damage to the material they’re embedded in. Here are the 5 most common types of bolt and screw extractors.
Bolt & Stud Extractor Tool
Stud extractors are a special fitting that can be used on most drills and drives. They come in both a cylindrical and cone shape. Simply attach one end to the drive and push the other end over your stud.
The cone can be adjusted for a better grip, although the cylinder will need to be properly sized. Once the tool has locked down on your exposed stud, simply unscrew or twist it loose.
At first glance, these resemble regular sockets. However, the inner edges are rounded instead of straight and have spiral teeth on the inside.
The perfect tool for removing bolts where the heads have been badly rounded, they are extremely simple to use.
To remove the bolt, simply attach the extractor to a ratchet and place over the damaged head. You can tap it on using a hammer or wrench as well. Then, simply turn the wrench to unscrew your bolt.
A hex top on the extractor makes it easy to use a wrench instead of a ratchet. Once removed, you will need to use a center punch to knock the bolt out of the extractor.
This sub-group of pliers come in a variety of shapes, from seemingly normal looking pliers to tongs.
They’re best used when the screw or bolt is sticking slightly out, as the tool needs something to grip.
It is then used to unscrew or pull the broken fastener from its hole.
Multi-Spline Screw Extractor
Spline screws are screws with multiple points (or splines) in the head, and generally resemble recessed stars.
More compact than spiral screw extractors, these socket-compatible extractor heads are short and function the same as their longer siblings using a ratchet to fit into tighter spaces.
Spiral Screw Extractor
These extractors resemble drill bits and are used for screws that are broken or stripped. The thread should run in the opposite direction as the screw’s threads.
Affix the extractor to a tap wrench and insert it into the freshly drilled hole. Turn counterclockwise until it no longer turns, then continue to tighten with a wrench until the screw pops loose. Extract by pulling the screw out with pliers.
Preparing for Screw Extraction
When using a screw extractor, you will need to prepare the bolt, screw, or stud. This involves placing a center punch in the middle of the head (or shaft, if the heads broken off) and gently tapping a divot for the extractor to follow.
Apply a drop of thread cutting oil (you can also use WD-40) to the screw or bolt for lubrication.
Using a drill bit one size smaller than the screw, gently drill between ⅛ and ¼ inch down into the screw shaft. Be careful not to go off-center or use too much pressure. The resulting hole should be big enough for the tip of the extractor to fit into.
Safety Note: You should always wear safety goggles whenever extracting, as there is a risk of metal shards flying into your eyes during the process.
