S-90315A511 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
• Effortless installation via thread forming design that creates strong, permanent threads in sheet metal without pre-tapping.
• Secure, flush seating with standard oval head profile and 82° countersink angle for smooth, professional finishes.
• Optimized drive engagement using Phillips No. 2 drive to reduce cam-out and speed up assembly processes.
• Full-length threading for maximum grip and uniform load distribution across the entire fastener length.
• Precise dimensional accuracy with Class 2A thread tolerances ensuring consistent performance and interchangeability.
• Environmental compliance meeting RoHS 3 and REACH standards for safe, sustainable industrial use.

Professional Applications & Engineering Value

These No. 10-12 thread forming screws are engineered to solve common challenges in sheet metal assembly, where material thinness and corrosion susceptibility often compromise joint integrity. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, extending service life in demanding conditions. The thread forming (Type A/AB) design displaces material to create robust internal threads, eliminating the need for tapped holes and reducing installation time. Combined with the oval head and 82° countersink, this screw ensures a secure, flush fit that prevents snagging and maintains aerodynamic or aesthetic surfaces in HVAC, electronics enclosures, and automotive panels. The Phillips drive offers reliable torque transfer, minimizing tool slippage during high-volume production.
