Tools & Gear Screw & Bolt Extractors Clam Shell

• Size 5 Screw Extractor - Clam
• Chrome alloy spiral screw extractor.
• Coarse-pitched tapered screw thread.
• Spiral flute screw extractors are ideally suited for removing broken bolts, studs & socket screws from medium to hard metals.
• Typically the required screw extractor will be approx. 2/3 the diameter of the fixing you are extracting.
• Use a centre punch to mark the centre of the fixing before drilling to prevent the drill bit wandering.
• Select a drill bit that is suitable for drilling into the specific material - typically HSS or HSS-Co5. Ideally the drill should be “Left Hand" which will prevent further tightening of the fixing during drilling.
• When using left hand drills ENSURE THE DRILL IS SET TO REVERSE.
• Drill pilot hole in centre of broken bolt, screw or stud.
• Lightly tap screw extractor into hole and turn anti-clockwise with a tap wrench or spanner.
• Damaged bolt, screw or stud will unwind out of the hole.
• Avoid excessive lateral loads - breakage could result.
• Wear eye and hearing protection.
