When it comes to industrial fastening, M3-M6 stainless Phillips machine screws offer unmatched reliability. These ISO certified screws meet strict international standards for safety and durability. Crafted from premium stainless steel, they deliver corrosion resistance and long-term fastening stability. Whether for electronics, automotive, or marine projects, they ensure secure assembly without compromise.
Outdoor and marine installations expose fasteners to water and chemicals. Mild steel screws often corrode quickly.
Solution: Stainless Phillips machine screws with lead-free compliance resist rust and oxidation. The high chromium content forms a protective layer, ideal for marine and industrial use.
Small components in electronics or machinery require exact thread sizing. Poorly made screws can damage internal parts.
Solution: M3-M6 stainless screws have precision-cut threads that match ISO specifications, ensuring smooth engagement and preventing material stripping.
Low-quality fasteners may slip or deform under torque, causing assembly delays.
Solution: Phillips head design offers a balanced grip for powered and manual tools, ensuring consistent torque without cam-out.
Projects for export require components that meet recognized safety standards.
Solution: These machine screws are ISO certified, guaranteeing uniform quality and international acceptability.
Frequent assembly and disassembly can wear down screw heads.
Solution: Hardened stainless alloy resists wear, extending the service life of each screw even in high-use environments.
These M3-M6 stainless Phillips machine screws are typically made from A2-70 or A4-80 stainless steel, containing 16–18% chromium and 8–10% nickel. This ensures high tensile strength and excellent corrosion resistance.
Tensile Strength: Up to 700 N/mm² for A2-70
Hardness: 210 HV min
Salt Spray Resistance: Over 1000 hours without red rust (ASTM B117 test)
ISO Certification: ISO 9001 manufacturing process control
Phillips Drive: Reduces cam-out and improves torque transfer.
Machine Thread: Precision-rolled threads for accurate fit and reduced friction.
Head Options: Available in pan, countersunk, and button head styles.
Using certified hardware reduces the risk of product failure and ensures compliance with safety standards. These screws undergo rigorous inspection during manufacturing, including dimensional accuracy, material composition, and mechanical performance tests.
ISO certification also ensures traceability, so every batch can be tracked to its raw material source. This is essential for industries like aerospace, automotive, and medical device manufacturing.
Electronics: Secure PCB boards and internal frames without damaging delicate parts.
Marine: Perfect for boat fittings, deck assemblies, and underwater equipment.
Automotive: Ideal for securing engine covers, panels, and metal brackets.
Industrial Machinery: Withstand high vibration and temperature changes.
Construction: Used in stainless steel fixtures and architectural details.
Choose Correct Grade: Use A4-80 grade for marine or chemical exposure.
Proper Torque: Avoid over-tightening to preserve thread integrity.
Storage: Keep in a dry, cool environment before use.
Lubrication: Apply thread lubricant for high-torque applications.
The M3-M6 stainless Phillips machine screws deliver ISO certified quality, corrosion resistance, and unmatched fastening reliability. They are the ideal choice for industries requiring precise, long-lasting assembly solutions.
Whether you are securing delicate electronics or heavy-duty marine equipment, these screws ensure performance that meets international standards.
