S-95560A112 10-32 x 3/8" 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 industrial environments and chemical exposure.
• High tensile strength of 80,000 psi ensures reliable, long-lasting fastening under significant mechanical stress.
• Class 2A fine UNF thread fit provides precise, secure engagement and reduces the risk of cross-threading during assembly.
• Integrated flange on the rounded button head distributes clamping force over a wider area, minimizing surface damage and improving joint stability.
• Convenient 1/8" hex drive allows for easy installation and removal with standard tools, speeding up assembly processes.
• Full threading along the 3/8" length offers maximum grip and adjustability in a wide range of material thicknesses.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and unrestricted use in global markets.

Professional Applications & Engineering Value

This 316 stainless steel flanged rounded head screw is engineered to address common challenges in demanding applications such as marine hardware, chemical processing equipment, and food-grade machinery. Its fine 10-32 UNF threading and Class 2A fit ensure a tight, vibration-resistant seal, critical for maintaining integrity in dynamic or high-pressure systems. The wide button head profile combined with the integral flange eliminates the need for a separate washer, reducing part count and assembly time while providing a clean, finished appearance. The material's inherent corrosion resistance and high Rockwell B85 hardness protect against degradation from moisture, acids, and salts, significantly extending service life and reducing maintenance costs in corrosive industrial environments.
