Brass Hex Head Screws
Fully Threaded
Partially Threaded
Brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance. Length is measured from under the head.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Fine threads are closely spaced to prevent loosening from vibration.
Screws that meet ASME B18.2.1 comply with specifications for dimensional standards.

Bronze Hex Head Screws
Fully Threaded
Partially Threaded
Bronze screws are 30% stronger than brass screws and provide more corrosion resistance to salt water, gases, and sewage. They are nonmagnetic and electrically conductive. Dimensions meet ASME B18.2.1 specifications. Length is measured from under the head.

Metric Thread-Forming Screws for Soft Metal
These screws have a triangular shank that presses tightly as it forms threads, so screws resist loosening in soft metals such as brass, aluminum, and copper. They’re also known as Taptite® screws. Made from steel, they're zinc-plated steel to resist corrosion in wet environments. Length is measured from under the head.
Screws that meet DIN 7500 adhere to international standards for thread-forming screw dimensions. The letter at the end of the standard refers to the screw’s drive type—C for Phillips and D for hex head.

Electrical Grounding Screws
The green color identifies these as grounding screws. They have a flange that provides a wide flat surface for making solid electrical connections. Screws cut threads in drilled holes as they’re turned, so they require less driving torque and cause less stress on your material than thread forming screws. Length is measured from under the flange. Head height includes the flange.
