S-96660A154 6-32 x 1/4" Steel Flanged Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 120,000 psi ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
• Zinc-plated alloy steel construction provides excellent corrosion resistance, extending service life in harsh or outdoor environments.
• Class 3A thread fit offers tighter tolerances for superior thread engagement and vibration resistance, minimizing loosening over time.
• Fully threaded design with coarse UNC threads allows for faster installation and stronger holding power in a variety of materials.
• Integrated flange and rounded button head distributes clamping force evenly, eliminating the need for a separate washer and providing a low-profile, finished appearance.
• Hex drive compatibility (5/64") enables secure tool engagement and high torque application, speeding up assembly and disassembly processes.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global standards for restricted substances, supporting sustainable procurement.

Professional Applications & Engineering Value

These 6-32 UNC thread screws are engineered from zinc-plated alloy steel to address common industrial challenges such as corrosion, vibration-induced loosening, and high mechanical stress. The coarse thread spacing and Class 3A fit provide excellent grip in metals, plastics, and composite materials, making them ideal for assembly lines, machinery, and electronic enclosures where precision and durability are critical. The flanged, rounded head design not only enhances aesthetics but also prevents surface damage and improves load distribution. With a Rockwell C32 hardness and full threading, these screws deliver consistent performance in demanding applications like automotive, aerospace, and heavy equipment, ensuring long-term reliability and reduced maintenance costs.
