S-91305A005 M1.6 x 6 mm JCIS10-70 JIS Steel Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Precise JIS No. 0 drive compatibility ensures secure tool engagement and reduces stripping during installation
• High tensile strength (60,000 psi) provides reliable fastening integrity under mechanical stress
• Class 4h thread fit delivers consistent mating accuracy with reduced vibration loosening
• 90° countersink angle design enables flush mounting for clean, professional finishes
• Fully threaded configuration maximizes grip length and load distribution across applications
• Rockwell B71 hardness rating maintains thread form integrity through repeated installation cycles

Professional Applications & Engineering Value

These M1.6 metric flat head screws address critical challenges in precision assembly where space constraints and vibration resistance are paramount. The zinc-plated steel construction provides essential corrosion protection for electronics, instrumentation, and automotive components exposed to moderate environmental conditions. The JIS drive system prevents cam-out issues common in high-torque applications, while the coarse pitch threading (0.35mm) ensures rapid installation in brittle materials without compromising holding power. The fully threaded design with Class 4h tolerance maintains consistent clamping force across the entire 6mm length, making these flat head screws ideal for PCB mounting, enclosure assembly, and miniature mechanical systems requiring reliable, low-profile fastening solutions.

Specification Summary & Compliance

Manufactured to JCIS10-70 specifications with Class 4h thread fit precision and metric coarse threading (M1.6x0.35mm). Features 90° countersink angle and fully threaded 6mm length. Compliant with RoHS 3 (2015/863/EU) environmental regulations for industrial use.
