Screws and Bolts

Brass Hex Head Screws

Brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Bronze Hex Head Screws

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.

Brass Socket Head Screws

Brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Bronze Socket Head Screws

Bronze screws are about 40% stronger than brass screws and provide more corrosion resistance to salt water, gases, and sewage. They are nonmagnetic and electrically conductive.

Metric Thread-Forming Screws for Soft Metal

These metric 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.

Hex Head Thread-Forming Screws for Metal

These screws have a hex head for a secure grip with a wrench.

Steel Hex Head Thread-Cutting Screws for Metal

These steel screws are zinc plated to resist corrosion in wet environments.

Stainless Steel Hex Head
Thread-Cutting Screws for Metal

Made from 410 stainless steel, these screws are strong, wear resistant, and mildly chemical resistant.

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.

Brass Button Head Hex Drive Screws

Brass button head screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

Metric Brass Button Head Hex Drive Screws

Made from brass, these metric button head screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

Brass Hex Drive Flat Head Screws

Brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Metric Brass Hex Drive Flat Head Screws

These metric brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Brass Precision Shoulder Screws

Brass shoulder screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Metric Brass Precision Shoulder Screws

Offered in metric sizes, these brass shoulder screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Brass Cup-Point Set Screws

Brass set screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.
