Color classification
304/316 stainless steel UNC US imperial cylindrical/cup head hex non-knurled machine screws are precision industrial fasteners, engineered for compatibility with American-standard equipment. Adopting the UNC (Unified National Coarse) thread standard—ideal for general industrial, automotive, and hardware applications—these screws feature a non-knurled design, cylindrical/cup head, and internal hex drive, delivering reliable fastening for machinery, electronic devices, and US-standard assemblies.
 
Crafted from premium 304/316 stainless steel, they offer exceptional corrosion and rust resistance: 316 grade excels in harsh, humid, or chemical environments, while 304 grade suits general indoor/outdoor use. The cylindrical/cup head provides a smooth, low-profile finish with wide contact area to protect workpieces, and the internal hex drive enables secure torque control and slip-proof installation with standard imperial tools. The non-knurled surface ensures clean, uniform seating, making them ideal for applications requiring a sleek, unobtrusive fastener.
