S-90316A218 10-32 x 7/8" ASME B18.6.3 Stainless Steel Flanged Hex Head Screws with Slotted Drive

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and outdoor applications.
• High tensile strength of 100,000 psi ensures reliable, long-lasting fastening under significant mechanical stress and vibration.
• Fine UNF threading (10-32) provides a tighter, more secure fit compared to coarse threads, reducing the risk of loosening.
• Flanged hex head design eliminates the need for a separate washer, distributes load evenly, and speeds up installation.
• External Hex/Slotted Drive offers versatile tool compatibility for both wrenches and screwdrivers, enhancing assembly flexibility.
• Precise Class 2A thread fit guarantees consistent, easy assembly and interchangeability with standard UNF nuts and tapped holes.
• Full compliance with ASME B18.6.3, RoHS 3, and REACH ensures product quality, safety, and environmental responsibility for global supply chains.

Professional Applications & Engineering Value

This 10-32 UNF 18-8 Stainless Steel Hex Head Screw is engineered to address critical challenges in demanding industrial settings. Its corrosion-resistant material and fine thread spacing make it exceptionally suitable for applications where exposure to moisture, chemicals, or extreme temperatures is a concern, such as in marine equipment, food processing machinery, and chemical plant assemblies. The combination of a flanged head and external hex/slotted drive simplifies installation while providing a larger bearing surface, which helps prevent surface damage and maintains joint integrity under dynamic loads. With a Rockwell B100 hardness and high tensile strength, this screw delivers reliable performance in high-vibration environments, reducing maintenance needs and downtime. Ideal for industrial screws and hex head bolts applications, it ensures long-term reliability and cost-efficiency in your assembly processes.
