Compare to: 4533-632-AL An opening with a partial internal thread at one end an externally threaded post at the opposite end It is used to hold two components at a given distance from each other. Standoffs are usually chosen over spacers when longer sizes are required Hex standoffs can be installed with a nutsetter or other wrenching device

Male standoffs are used when one of the components is internally threaded. Aluminum is popuar for its lightweight / strength compromise. It is non-magnetic, performs well in severe temperatures, and has insulating properties. Nylon is a good insulator and has a surface smoothness which will not fray the insulation of wires that rub against it. Its threads are will withstand torque without stripping. Brass is used in making high-quality standoffs. It is conductive, resists corrosion and is non-magnetic. It is costlier and heavier than aluminum and is usually plated in zinc or nickel. Stainless has advantages of brass but has superior resistance to corrosion and chemical fumes. Steel is used for its greater strength, but it is heavier than aluminum and does not resist corrosion like aluminum or brass.
