S-96660A179 3/8"-16 x 1 1/2" Steel Flanged Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 120,000 psi tensile strength for reliable performance in high-stress applications
• Superior corrosion resistance provided by zinc-plated alloy steel construction, extending service life in harsh environments
• Enhanced installation efficiency through the 7/32" hex drive design that prevents cam-out and allows high torque application
• Secure fastening with Class 3A thread fit ensuring precise engagement and vibration resistance in critical assemblies
• Reduced assembly complexity with integrated flange design that eliminates the need for separate washers
• Optimized for rapid installation featuring UNC coarse threading that resists cross-threading and speeds up assembly processes
• Compliance with international standards including RoHS 3 and REACH for global manufacturing and environmental safety

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these zinc-plated alloy steel rounded head hex screws deliver critical performance advantages in construction, heavy machinery, and structural assemblies. The Class 3A UNC coarse thread configuration provides superior engagement in various materials while resisting vibration-induced loosening - a common failure point in dynamic environments. The integrated flange design distributes clamping force over a wider surface area (0.813" diameter), preventing surface damage and maintaining joint integrity. With full threading along the entire 1-1/2" length, these screws offer maximum adjustability and holding power, making them ideal for applications where high tensile strength and corrosion resistance are paramount for long-term reliability.
