S-94414A622 3/8"-16 x 3/4" ASME B18.3, ASTM F835 Alloy Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional torque transmission and anti-camout performance with Torx Plus IP45 drive for reliable fastening in high-stress industrial applications
• Superior corrosion resistance and durability thanks to black-oxide coating on alloy steel, extending service life in demanding environments
• High-strength construction withstands extreme loads with 140,000 psi tensile strength and Rockwell C39 hardness for heavy-duty assemblies
• Precise, secure thread engagement through Class 3A fit and fully threaded UNC coarse spacing, reducing vibration loosening risks
• Flush, low-profile installation with standard 82° countersink angle and flat head design for smooth surface finishes
• Enhanced drive longevity and reduced tool wear with Torx Plus technology, lowering maintenance costs in repetitive assembly operations
• Full regulatory compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial use

Professional Applications & Engineering Value

Engineered for heavy-duty industrial fastening, these 3/8"-16 UNC flat head screws address critical assembly challenges in machinery, automotive, and construction sectors. The black-oxide alloy steel construction provides excellent resistance to corrosion and wear, while the Torx Plus IP45 drive ensures maximum torque transfer without stripping—crucial for high-vibration environments. With fully threaded Class 3A fit and coarse thread spacing, these screws deliver superior holding power in metals and composites, minimizing the risk of joint failure. The 82° countersink angle enables seamless flush mounting, ideal for applications where surface protrusion is unacceptable. These features collectively enhance assembly reliability, reduce maintenance intervals, and support efficient production workflows in industrial fastener systems.
