BEX-H7 is an expanded 7-piece industrial straight-flute extractor set engineered to back out broken screws, sheared heavy-duty studs, and snapped threaded pipe nipples without radial wall expansion. Calibrated for pilot drill bit diameters from 1/8″ to 9/16″ (3 mm to 14 mm), the BEX-H7 uses vertical splines that bite straight into pre-drilled holes, avoiding the wedge effect of spiral extractors that locks hollowed fasteners tighter against casting threads. Operable with tap wrenches or adjustable spanners, it safely extracts seized hardware up to 7/8″ (M22) and threaded pipes up to 5/8″ NPT/BSP

Feature
Q1: What extra capacity does the BEX-H7 offer compared to the BEX-H5?
A: The BEX-H5 includes sizes #1 through #5 (drill bit sizes 1/8″ to 3/8″). The BEX-H7 adds the larger #6 (15/32″ / 12 mm) and #7 (9/16″ / 14 mm) extractors, increasing bolt extraction capacity up to 7/8″ (M22) and pipe extraction capacity up to 5/8″ NPT/BSP.
Q2: Why use straight-flute extractors instead of spiral flutes on pipe nipples?
A: Threaded pipe nipples have thin hollow walls. Tapered spiral extractors act like expanding wedges, pushing the thin pipe wall outward and locking its threads even tighter into the casting. Straight flutes bite vertically into the wall without radial expansion, turning the pipe out without thread binding.
Q3: How are the BEX-H7 extractors driven?
A: Each extractor features a ground square driving head. You can turn them using a standard tap wrench, an adjustable wrench (like the HansTools 1170-8), or an open-end spanner.
