Value Collection 312-8929 Spiral Flute Screw Extractor Size 9

Product Description

The VALUE COLLECTION 312-8929 is a Size 9 spiral flute screw extractor designed to remove broken or seized fasteners in the 1-3/8 to 2 inch diameter range, including 1 inch NPT and 1 inch BSP threaded fasteners, as well as metric sizes from 36 to 52 mm. The tool measures 4-5/8 inches overall length, giving the technician adequate reach and torque leverage in confined spaces. Spiral flute geometry bites into damaged fastener heads as rotational force is applied, making removal possible without damaging surrounding material. Licensed tradespeople and maintenance mechanics rely on this extractor for field repair, machinery overhaul, and general fastener removal tasks.

This extractor is suited for use in industrial maintenance, mechanical repair shops, and job-site service work where large-diameter broken bolts or studs must be removed. It covers a broad fastener range that includes both inch-standard NPT and BSP pipe fittings and metric fasteners, making it a practical choice for shops that work across multiple fastener standards. Typical applications include removing broken pipe plugs, large cap screws, and hex bolts in industrial and commercial equipment.

Installation Notes

This tool is installed by mechanics, maintenance technicians, and tradespeople performing fastener removal tasks. Before use, drill a pilot hole into the center of the broken fastener using a left-hand drill bit sized to the extractor manufacturer recommendations. Apply the extractor with a tap wrench or appropriate drive tool, turning counterclockwise to engage the flutes and back out the broken fastener. Never apply excessive side load to the extractor, as hardened extractor material can fracture if torqued beyond its rated capacity.
