Value Collection 312-8931 Spiral Flute Screw Extractor Size 11

Product Description

The VALUE COLLECTION 312-8931 is a Size 11 spiral flute screw extractor designed to remove broken or seized screws and fasteners in the 2.5 to 3 inch range. The spiral flute design bites into damaged fastener heads as reverse torque is applied, allowing removal without destructive drilling in most cases. This extractor is a standard tool for HVAC technicians, plumbers, electricians, and general trade professionals who encounter stripped or broken fasteners during service and installation work. At 10.48 pounds, the set offers substantial build quality suited for repeated shop or field use.

This extractor is used in applications where fasteners have been damaged beyond the reach of standard removal tools. Compatible screw sizes include 2.5 to 3 inches, 1.5 inches NPT, 1.5 inches BSP, and M68 to M80 metric fasteners. It is well suited for residential and commercial mechanical rooms, equipment panels, pipe flanges, and structural assemblies where heavy-duty fasteners are common. Trade professionals will find this size particularly useful when working on large equipment with correspondingly large threaded hardware.

Compatibility

Compatible with screws and fasteners ranging from 2.5 to 3 inches, 1.5 inches NPT, 1.5 inches BSP, and M68 to M80 metric sizes. Designed as an OEM-style replacement or direct-use screw extractor for trade and industrial applications requiring Size 11 extraction capability.

Installation Notes

Screw extractors are installed by a qualified tradesperson using a drill press or hand drill with a properly sized pilot hole drilled into the center of the broken fastener before insertion. Always de-energize and lock out any equipment before attempting fastener removal on electrical or mechanical assemblies. Apply steady, controlled reverse-direction torque to avoid snapping the extractor inside the fastener. Follow applicable trade safety codes and equipment manufacturer guidelines when servicing equipment containing broken hardware.
