S-91420A183 M3.5 x 16 mm DIN 965 Steel Phillips Flat Head Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, extending service life in demanding environments
• Superior holding power from 60,000 PSI tensile strength and Rockwell B71 hardness for reliable load-bearing performance
• Precise flush installation enabled by the 90° countersink angle and flat head design, minimizing protrusion risks
• Efficient assembly with Phillips No. 2 drive providing secure tool engagement and reduced cam-out
• Consistent thread engagement due to Class 6h fit and coarse M3.5x0.6mm threading, ensuring vibration resistance
• Full-threaded design maximizing grip length and distribution of stress along the entire 16mm shaft
• Regulatory compliance meeting DIN 965 standards, RoHS 3, and REACH for global industrial acceptance

Professional Applications & Engineering Value

Engineered for industrial fastening where precision and durability are critical, this M3.5 metric screw addresses common challenges like material fatigue and loosening under stress. The zinc-plated steel offers a protective barrier against oxidation, ideal for machinery, automotive assemblies, and electronic enclosures exposed to humidity. Its fully threaded body and Class 6h fit provide uniform clamping force, reducing the need for frequent retightening in vibrating equipment. The flat head with 90° countersink ensures a seamless surface finish, preventing snagging in automated production lines. Complying with DIN 965, it guarantees interchangeability and reliability in metric hardware systems, streamlining maintenance and reducing downtime.
