Bahco 1420-1.4 Estrattore viti n. 4 (1.4)

For mechanics and maintenance technicians facing a snapped bolt or stripped screw, the Bahco 1420-1.4 screw extractor removes broken fasteners from threaded holes. The left-hand spiral flutes bite into the drilled pilot hole and turn the remnant counter-clockwise to back it out. Use it with a tap wrench or adjustable wrench on the square drive.

Key specifications

• Extractor size: No. 4 (1.4)
• Material: High Speed Steel (HSS)
• Flute design: Left-hand spiral
• Drive type: Square drive
• Recommended drill bit diameter: 4.5 mm
• Recommended screw/bolt size: M6 - M8 (1/4" - 5/16")
• Overall length: 55 mm
• Shank size (square): 4.5 mm
• Finish: Black oxide

Why choose it

The HSS body is hardened for strength and wear resistance, and the black oxide finish helps protect against corrosion. The left-hand spiral is designed to grip the fastener as you turn counter-clockwise, so the extractor does not slip under load.

Ideal use cases

• Removing broken screws, bolts, and studs from metal parts
• Extracting fasteners with damaged or rounded heads
• Workshop and field repair where drilling a pilot hole is possible

Good to know

Drill a pilot hole of 4.5 mm into the broken fastener, then insert the extractor and turn counter-clockwise. The square shank fits a tap wrench or adjustable wrench for a secure grip.
