When standard fasteners fail in wet, salty, or chemically aggressive conditions, you need hardware built to last. Whether you're a marine fabricator, industrial maintenance tech, or serious DIYer, using the wrong screw grade can mean rust, seizing, and structural failure — often at the worst possible time.
These Phillips pan head machine screws are precision-manufactured from 316 stainless steel — a molybdenum-enhanced alloy that delivers exceptional resistance to chloride corrosion, oxidation, and pitting. Available in M5, M6, and M8 diameters with lengths ranging from 6mm to 100mm (approx. 0.24" to 3.94"), they cover a wide range of metric fastening needs.
Ideal for boat deck hardware, outdoor enclosures, food-processing equipment, chemical plant fixtures, and precision DIY assemblies where long-term reliability is non-negotiable. The pan head profile provides a wide bearing surface, and the Phillips drive ensures compatibility with standard hand and power tools.

These screws are made from 316 stainless steel, which offers superior corrosion resistance compared to standard 304 grade — making them ideal for marine, coastal, and chemical environments.
Yes. 316 stainless steel is widely used in seawater equipment, boat fittings, and outdoor structures due to its excellent resistance to saltwater and chloride corrosion.
These are Phillips (cross-head) drive screws, compatible with standard #2 Phillips screwdrivers and power drill bits.
These screws follow the metric thread standard (ISO). M5, M6, and M8 refer to the nominal outer diameter of the thread in millimeters.
As a general rule, the screw length should be approximately 2–3 times the diameter for most fastening applications. For through-bolting, measure the total material thickness and add 3–5mm for nut engagement.
Yes. These machine screws are compatible with standard metric hex nuts, flange nuts, and nylon lock nuts in the corresponding M5, M6, or M8 thread size.
