Inch Sizes Cup Point Brass Socket Set Screws

Brass cup point socket set screws are specialized fasteners designed for precision fastening with a soft-touch grip. Made from high-quality brass, these set screws are ideal for non-magnetic, corrosion-resistant, and electrically conductive applications, making them a top choice for industries such as electronics, marine, instrumentation, and decorative hardware.

The cup point design features a concave tip that bites gently into the mating surface, offering secure holding power without excessive damage—perfect for use on softer materials like aluminum, copper, or plastic. This makes brass cup point set screws especially valuable when working with delicate components, rotating parts, shafts, knobs, and collars, where a firm hold is required but surface protection matters.

Brass is naturally resistant to corrosion, especially in moist or marine environments, and does not rust like steel. It also provides excellent thermal and electrical conductivity, which makes these screws ideal for grounding terminals, electrical contacts, and low-voltage connections.

Specifications include:

• Drive Type: Internal hex (socket)

• Point Type: Cup point

• Material: Solid brass

• Finish: Natural (uncoated, corrosion-resistant)

• Standards: ASME B18.3 or DIN equivalents

• Sizes: Commonly available from #4-40 to 1/2-13 and metric sizes

Whether you're building sensitive electronics, installing antique hardware, or outfitting a boat, brass cup point socket set screws deliver the perfect balance of strength, conductivity, and corrosion resistance. Their attractive appearance also makes them a great choice for visible installations where aesthetics matter.
