Using a center punch and a ball peen hammer, place the point of the center punch in the exact center of the broken bolt or screw and firmly tap the striking surface of the punch to score the top of the bolt or screw. The extractor is then inserted into this hole and turned in the direction opposing the stuck screw's original one, usually using a tap wrench. Where this is not possible, use an aerosol-type penetrating oil with the plastic extension inserted in the spray nozzle to get the lubricant to thread level.
These flutes or grooves grip the rounded nut from the outside, rather than being driven into the hollowed out screw shaft and taking hold of it internally as a screw extractor would. Do not jerk on the wrench while attempting to turn the easy out extractor or subject it to side-to-side force. If neither is available, use a properly sized end wrench, adjustable crescent-type wrench or a pair of vice grips. Use either an adjustable T-handle wrench such as those used with tap and die sets or a ratchet with properly sized adapter attachment to turn the easy out extractor. This size is often non-standard for most drill sets, requiring a dedicated drill bit to be supplied with the kit.Insert the easy out into the hole drilled in the center of the broken bolt or screw and then gently tap it home with a hammer so it bites into the metal of the bolt or screw.
Easy out extractors are manufactured from hard but brittle steel and subjecting them to lateral force can easily cause them to snap, which will leave you in an even worse position than before. Screw extractors are intentionally made of hard, brittle steel, and, if too much torque is applied, can break off inside the screw that is being removed.
Properly used, easy outs can often save you more expensive and time-consuming procedures such as re-boring and re-tapping, which often must be performed by a machinist.
This wedging action can lock the screw even more tightly in place, making it difficult or impossible to extract. DURABLE CASE- This bolt remover set comes in a durable and handy case to ensure optimum portability and to keep the extractor screws separate from all other screw removal drill bits. Based in Arlington, Texas, Larry Darter has been writing articles on a broad range of topics including building and construction, outdoor recreation and personal finance since 2009.
Each EASY-OUT has a right-hand thread which embeds itself into the hole drilled by a corresponding (matching) Right-Hand HSS Jobber Drill Bit (drill bits are not included).
When used properly, easy out extractors will often successfully remove the most stubborn broken bolts and screws. DIFFERENT SIZES - This damaged screw extractor comes with 5 different size so you can have wide variety of size to unscrew damaged screws. The extractor is then hammered into the hole with a brass hammer, because a steel hammer is more likely to cause the extractor to break.They are generally left-handed, for use on right-handed threads, though there are right-handed extractors for removing left-handed screws.
