316 Stainless Steel Phillips Pan Machine Screws — Corrosion-Resistant Metric Fasteners for Demanding Environments
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.
Compatible with standard metric hex nuts, flange nuts, and nylon lock nuts in M5, M6, and M8 thread sizes.
- 316 Stainless Steel Construction — Molybdenum-alloyed for superior resistance to saltwater, acids, and chloride environments vs. standard 304 grade
- Phillips Pan Head Drive — Cross-head design works with standard #2 Phillips drivers and common power drill bits for fast, reliable installation
- Full Metric Size Range — M5, M6, and M8 diameters with lengths from 6mm to 100mm to cover structural, panel, and precision fastening tasks
- Marine & Industrial Grade — Widely specified for seawater equipment, chemical processing, dyestuff, and paper industry applications
- Flexible Quantity Options — Available in packs of 5, 10, 20, 30, and 50 pieces to match project scale without over-ordering
- Flat-Tailed Bolt Profile — Pan head with flat underside ensures flush, stable seating against flat surfaces and flanged components

❓ Frequently Asked Questions
What sizes are available for these machine screws?
These screws are available in M5, M6, and M8 diameters, with lengths ranging from 6mm to 100mm depending on the size. Select your preferred size and quantity from the variant options above.
What grade of stainless steel is used?
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.
Are these screws suitable for outdoor or marine use?
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.
What drive type do these screws use?
These are Phillips (cross-head) drive screws, compatible with standard #2 Phillips screwdrivers and power drill bits.
What thread standard do these screws follow?
These screws follow the metric thread standard (ISO). M5, M6, and M8 refer to the nominal outer diameter of the thread in millimeters.
How do I choose the right length for my project?
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.
Can I use these screws with standard hex nuts?
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.
