    Nonsparking L-Keys

    Made of beryllium copper that is Factory Mutual (FM) approved, these L-keys won't create sparks when scraped, struck, or dropped. They help you meet OSHA requirements when fastening screws in hazardous environments where flammable liquid, dust, or gas could be lurking. Use them everywhere from oil and gas refineries to paper mills.
    Warning: Do not use these tools in direct contact with acetylene.
    Short—A short long leg fits into tight spaces where you have less room to swing, making these ideal for confined areas.
