NEIKO 04204A Hex-Head Multispline Extractor Set, 25 Pieces (1/8–7/8 in)

Overview

The NEIKO 04204A Hex-Head Multispline Screw and Bolt Extractor Set is built for professionals and DIYers who face stubborn fasteners. It includes 25 extractors spanning from 1/8 in to 7/8 in in 1/32 in increments. Each tip is precision machined from chrome molybdenum steel, delivering stiffness and dependable performance under high torque. The hex heads are designed for solid engagement with standard wrenches or sockets, and the aggressive multiplane teeth with a left hand spiral provide extra gripping power and faster threading into damaged fasteners.

Size markings and portability

A clear advantage is the laser etched size markings on every piece, making quick identification possible even on busy job sites. The set ships in a durable plastic case that keeps parts organized, protected, and easy to transport between the shop, vehicle, or on site. This thoughtful packaging supports fast setup and clean workspaces.
