DAYTON SE-500B 5-Piece Screw Extractor Set
The DAYTON SE-500B 5-Piece Screw Extractor Set is a professional-grade tool kit designed to quickly and efficiently remove broken screws, bolts, studs, and pipes without damaging the surrounding thread. Manufactured from hardened chrome vanadium steel, this extractor set provides the strength and durability needed for tackling even the most stubborn fastener removal jobs.
This comprehensive 5-piece set features spiral fluted extractors that bite securely into damaged or stripped fasteners, allowing for easy extraction through reverse rotation. The tapered design ensures a tight grip within the pre-drilled pilot hole, while the hardened construction resists breakage during high-torque applications.
Key Features:
- 5-Piece Complete Set: Includes five most commonly used extractor sizes (1/8", 1/4", 5/16", 7/16", 9/16"), covering a wide range of fastener removal applications
- Chrome Vanadium Steel Construction: Premium CR-V steel provides exceptional strength, durability, and resistance to wear and breakage during extraction
- Spiral Fluted Design: Spiral flutes screw into the pilot hole for secure engagement and allow controlled extraction through reverse rotation
- Left-Hand Thread: Reverse thread design grips tighter as you turn counterclockwise, providing superior holding power
- Tapered Profile: Gradual taper ensures progressive grip as the extractor is inserted deeper into the damaged fastener
- Square Drive Head: Square head design accommodates standard wrenches, adjustable wrenches, tap wrenches, or sockets for easy turning
- Thread-Safe Removal: Extracts broken fasteners without damaging the surrounding threads, allowing reuse of the same size bolt or screw
- Versatile Application: Works on various materials including steel, stainless steel, aluminum, brass, and cast iron
- Protective Storage Case: Includes durable plastic case for organized storage and protection when not in use
