S-99663A222 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• High torque transmission and easy installation thanks to the external hex/slotted drive, allowing for secure fastening with common tools.
• Enhanced load distribution and reduced risk of material damage from the integrated flange, which acts as a built-in washer.
• Reliable, permanent threads in sheet metal created by the thread forming tapping method, eliminating the need for a separate tapping operation.
• Full-length threading ensures maximum grip and holding power along the entire 1-inch shank.
• Simplified assembly process with compatibility for a standard No. 29 drill bit (0.136" diameter), streamlining sheet metal work.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global supply chains.

Professional Applications & Engineering Value

Engineered for demanding sheet metal assembly, this No. 8-15 TPI thread forming screw solves common industrial challenges. The 316 stainless steel material provides exceptional resistance to corrosion from chemicals, saltwater, and atmospheric exposure, making it perfect for marine, chemical processing, and food industry equipment. The thread forming design cold-forms a mating thread in the base material, resulting in zero chip production and a stronger, vibration-resistant connection compared to thread-cutting alternatives. Combined with the flanged hex head, it distributes clamping force over a wider area, preventing pull-through in thin gauge metals and reducing the need for separate washers, thereby speeding up assembly lines and lowering total installed cost.
