S-95560A113 10-32 x 1/2" Stainless Steel Oversized-Flange Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh or chemical-exposed environments.
• High mechanical strength and durability from 80,000 psi tensile strength and Rockwell B85 hardness for reliable, long-term performance.
• Secure, flush fastening thanks to the wide button head and integrated flange, which distributes load and resists pull-through.
• Efficient installation and removal with a 1/8" hex drive, providing excellent torque transfer and reducing tool slippage.
• Precise, reliable thread engagement with a Class 2A fit and fine 10-32 UNF thread, ensuring vibration resistance and a secure hold.
• Full thread coverage along the 1/2" length for maximum grip and adjustability in various material thicknesses.
• Compliance with strict environmental regulations, being RoHS 3 and REACH compliant for safe, global use.

Professional Applications & Engineering Value

This 316 stainless steel flanged rounded head screw is engineered to solve critical challenges in demanding industrial settings. Its exceptional corrosion resistance makes it a top choice for applications in marine, chemical processing, and food-grade equipment, where exposure to moisture and aggressive substances is common. The combination of a wide button head profile and an integral flange eliminates the need for a separate washer, providing a larger bearing surface that prevents damage to soft materials and maintains clamp load under vibration. The fine UNF thread and Class 2A fit deliver superior holding power in precision assemblies, reducing the risk of loosening. With a fully threaded design and hex drive, these screws offer quick, reliable fastening in tight spaces, enhancing assembly efficiency and product longevity in industrial fastening applications.

Specification Summary & Compliance
