Product Info
The ToolPRO Screw Extractor Set 15 Piece removes broken studs and bolts from engine blocks, cylinder heads, and other components where bolt failure would otherwise require expensive thread repair or part replacement. With sizes in both metric and SAE, it covers the fasteners you meet most often.
Each extractor features opposite tapered threads that lock progressively into the drilled-out bolt. Start by marking the bolt centre with a centre punch, drill a pilot hole, then select an extractor close to the bolt size that will not damage the surrounding thread. Screw the extractor anti-clockwise using a hand tap, adjustable spanner, sockets or locking pliers. As you apply pressure, the extractor bites harder and draws the broken bolt free. Once removed, the bolt separates from the extractor using locking pliers or a bench vice. Chrome molybdenum construction resists the stress of extraction work.
Metric sizes: 3, 4, 5, 5.5, 6, 8, 10, 11, 12, 14mm. SAE sizes: 1/8, 3/16, 1/4, 3/8, 1/2 inch. Includes handy carry case. Drill bits sold separately.
