Value Collection 312-8933 Spiral Flute Screw Extractor 3 Pc

Product Description

The VALUE COLLECTION 312-8933 is a 3-piece spiral flute screw extractor set designed to remove broken, stripped, or seized screws and fasteners. Each extractor uses a left-hand spiral flute design that bites into damaged fastener material as rotational force is applied, drawing the fastener out rather than driving it deeper. The set covers extractor sizes 4, 5, and 6, handling a screw size range of 7/16 inch through 1 inch. The full kit weighs 0.5 pounds, making it compact enough to carry in a standard tool pouch. This set is used by HVAC technicians, plumbers, electricians, and general tradespeople who regularly encounter fastener removal challenges in the field.

This extractor set is suited for residential and light commercial service work where broken bolts, screws, or pipe plugs need to be backed out without damaging surrounding threads or material. Compatible screw sizes range from 15/32 inch through 1 inch, covering a wide variety of fastener diameters encountered in mechanical, electrical, and plumbing installations. The set also covers pipe sizes 1/8, 1/4, and 3/8 inch, making it useful for removing damaged pipe plugs in addition to standard fasteners. It fits into typical extraction workflows where a left-hand drill bit is used first to create the pilot hole before the extractor is engaged.

Key Features

• Covers screw size range from 7/16 inch to 1 inch maximum capacity
• Spiral flute geometry applies extraction torque as backward rotation is applied
• Compatible with pipe sizes 1/8, 1/4, and 3/8 inch for plug removal applications
• Compact set at 0.5 pounds — fits standard tool pouches and service bags

Compatibility

Designed for use with broken or damaged screws and fasteners in the 7/16 inch to 1 inch size range, and pipe plugs in 1/8, 1/4, and 3/8 inch pipe sizes. Use with a appropriately sized left-hand drill bit to prepare the pilot hole prior to extractor engagement.

Installation Notes

De-energize or shut off any system before attempting fastener removal in electrical panels, HVAC equipment, or pressurized plumbing lines. Use a properly sized left-hand drill bit to drill a centered pilot hole into the broken fastener before inserting the extractor. Apply steady, controlled reverse-rotation torque — avoid impact drivers, which can snap the extractor in the pilot hole. Follow applicable codes such as NEC, IPC, or IFGC when working on systems that require fastener service as part of a regulated repair.
