S-95560A107 8-32 x 1/2" Stainless Steel Oversized-Flange Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction, ideal for chemical, marine, and outdoor applications.
• High tensile strength of 80,000 psi ensures reliable, durable fastening under significant mechanical stress and vibration.
• Flanged, rounded button head design provides a wider bearing surface for enhanced load distribution and a finished, low-profile appearance.
• Hex drive (3/32") allows for high-torque installation and removal, reducing the risk of stripping and improving assembly efficiency.
• Coarse UNC threads with Class 2A fit offer quick, easy engagement and robust performance in a variety of materials.
• Full threading along the 1/2" length ensures maximum grip and holding power throughout the entire fastener.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and unrestricted use in regulated industries.

Professional Applications & Engineering Value

This 8-32 UNC coarse thread screw in 316 stainless steel is engineered to solve critical challenges in demanding industrial settings. Its exceptional corrosion resistance makes it a top choice for applications exposed to moisture, chemicals, and salt spray, such as in marine hardware, chemical processing equipment, and food-grade machinery. The combination of 80,000 psi tensile strength and Rockwell B85 hardness ensures the fastener maintains integrity under high stress and vibration, preventing failure in critical assemblies. The flanged, rounded head and hex drive simplify installation, providing a secure, flush fit that minimizes protrusion and distributes clamp load effectively, which is vital for maintaining the integrity of assembled components in industrial fastening applications.
