The Rennsteig double-edged bolt extractors are a new generation of tools for easily removing damaged screws and bolts. The key feature of the new extractors is four double-edged cutting and gripping edges that equal eight points of contact. Designed for both left- and right-hand threaded screws, the extractor’s cutting edges provide nonslip engagement, allowing users to remove the toughest frozen bolts, the company said. The extractors feature a center point, so no additional tools are required to mark the center point for the drill hole. The high-alloy chrome-vanadium steel extractors feature a hexagonal driving flat that provides optimum torque. Extractors are available as individual pieces with a range of sizes from 1-7 for bolts 3⁄16 to greater than 1 inch or in three- and five-piece sets.
