    6-Point

    Socket

    Made of aluminum bronze, these sockets satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. The hex shape provides the best possible grip on hex fasteners and prevents rounding.
    Warning: Do not use these tools in direct contact with acetylene.

    Nonsparking Ratchet Wrenches

    Image of Product. Front orientation. Ratchet Wrenches. Nonsparking Ratchet Wrenches.
    Made of aluminum-bronze, these wrenches satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. A ratchet mechanism allows you to turn fasteners without removing and repositioning the wrench. The smaller the turn required to ratchet, the less clearance you need to engage the ratchet.
    Warning: Do not use these tools in direct contact with acetylene.

    Nonsparking Torque Wrenches

    Image of Product. Front orientation. Torque Wrenches. Nonsparking Torque Wrenches.
    These wrenches satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. Set the desired torque and the wrench indicates when it's reached with an audible click. To relieve pressure on the spring and maintain calibration, set torque to the lowest reading on the scale when not in use.
    Torque—You can tighten fasteners that require less torque than the values listed, but the accuracy ratings apply only within the specified range.

    Nonsparking 12-Point Impact Sockets

    Made of aluminum bronze, these sockets satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. The 12-point shape quickly positions on hex fasteners. Sockets are made to withstand the high torque and force of impact tools.
    Warning: Do not use these tools in direct contact with acetylene.

    Nonsparking 8-Point Impact Sockets

    Made of aluminum bronze, these sockets satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. With twice as many corners, 8-point sockets grab onto square-drive screws and nuts more quickly than 4-point sockets. Also known as double-square sockets. These sockets are sturdier and have more give than manual-drive sockets, so they'll withstand the high torque and force of impact tools. They can also be used with hand-drive tools.

    Brass Hex-Drive Precision Shoulder Screws

    Image of Product. Front orientation. Shoulder Screws. Brass Hex-Drive Precision Shoulder Screws.
    These screws are nonsparking, nonmagnetic, and won't rust. They are engineered to tight tolerances for assemblies that require smooth and accurate movement, with shoulder diameters twice as precise as those on standard-fit screws.
    360 Brass—These screws produce little friction, so they're ideal anywhere you need smooth motion without lubrication.
