    Nonsparking Alignment Pins

    Image of Product. Front orientation. Contains Annotated. Alignment Pins. Nonsparking Alignment Pins.
    Made from aluminum bronze that is Factory Mutual approved, these nonmagnetic, corrosion-resistant pins inhibit sparking. They satisfy OSHA requirements for nonsparking tools for locations where flammable vapors and combustible residues are present. Nonsparking tools are not, however, classified as antistatic because they do conduct electricity. Use alignment pins to align structural components such as I-beams and angle irons for bolting, riveting, and welding.
    Note: Do not use these tools in direct contact with acetylene.
