Chicago-Latrobe 65015 Screw Extractor 800 No 6-3/8 (Drill Size 31/64 in)

Professional screw extractor for broken fasteners

The Chicago-Latrobe 65015 is a spiral flute extractor designed to remove broken bolts and studs with right-hand threads. It fits bolt sizes from 15/16 in to 1 1/8 in and requires a 31/64 in drill size for the pilot hole. The carbon steel construction provides the hardness needed for gripping damaged fastener interiors. Mechanics and maintenance technicians use it when a bolt head shears off flush or below the surface.

Upgrades from basic straight-flute

This size 800 extractor handles larger diameter bolts that smaller extractor sets cannot engage. The spiral flute design bites deeper into the drilled pilot hole as torque increases, reducing the chance of the extractor slipping or breaking inside the bolt. The jump is worth it when removing seized or corroded fasteners in heavy equipment, truck frames or industrial machinery where bolt diameters exceed 15/16 in and standard extractor kits stop at smaller sizes.

11/16 in square drive for high-torque removal

The 3 3/4 in overall length and 11/16 in square drive accept heavy ratchets, breaker bars or impact sockets for maximum leverage. Carbon steel handles the torque required for bolts up to 1 1/8 in without twisting off, provided the pilot hole is drilled accurately to 31/64 in. It runs out when the bolt material is harder than the extractor, when the broken piece is too short to engage the flutes, or when the bolt uses left-hand threads which this right-hand tool cannot extract.
