Stainless 18 8 Cup Point Square Head Set Screw (Inch)
Stainless Steel 18‑8 cup point square head set screws offer a durable, corrosion‑resistant fastening solution ideal for industrial, marine, and equipment applications requiring strong holding power and easy field adjustment. Designed with a traditional square external head, these screws provide excellent wrench or plier engagement, allowing fast installation and removal even in dirty, greasy, or harsh outdoor environments.
The cup point features a concave, rounded seat that bites securely into the mating surface, offering reliable holding strength while minimizing excessive penetration or material deformation. This design makes the screws perfect for securing shafts, pulleys, collars, couplings, and components exposed to vibration or rotational loads.
Made from 18‑8 stainless steel, these screws deliver excellent rust resistance and long‑term durability—ideal for marine environments, washdown areas, food‑processing equipment, chemical exposure, and outdoor installations.

Cup point stainless steel square head set screws are widely used in machinery, maintenance, repair operations, and industrial assembly where non‑socket installation is preferred. The square head allows strong tool engagement using basic hand tools, making them ideal for field service or locations where hex keys aren’t accessible.
The 18‑8 stainless steel construction provides superior corrosion protection, making these screws suitable for harsh environments where carbon steel fasteners would fail. The cup point design secures components firmly without causing extreme surface damage, allowing repeated adjustments and long service life.
Available in multiple diameters and lengths to support OEM, MRO, and industrial mechanical applications.
