S-90184A542 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 Stainless Steel construction, ideal for harsh industrial environments and outdoor applications.
• Superior holding power in sheet metal due to thread forming design, which creates strong, permanent threads without pre-tapping.
• Reliable and efficient installation with a Phillips No. 3 drive, reducing cam-out and ensuring secure fastening.
• Full-length threading provides consistent grip along the entire shank for maximum load distribution and joint integrity.
• Optimized for use with a 5.5 mm (0.2165") drill bit, simplifying the installation process and ensuring precise fit in sheet metal up to 0.025" thick.
• Pan head design offers a low-profile, rounded finish that sits flush for a clean appearance and reduced snagging.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and suitability for global industrial supply chains.

Professional Applications & Engineering Value

These 316 Stainless Steel thread forming screws are engineered to solve common challenges in sheet metal fabrication, such as material fatigue and corrosion-induced failure. The thread forming tapping method displaces material to create a zero-clearance fit, eliminating the need for tapped holes and reducing assembly time. This design enhances vibration resistance and prevents loosening under dynamic loads, making them ideal for HVAC systems, electronic enclosures, and automotive panels. The Phillips drive ensures compatibility with standard tools, while the fully threaded shank provides uniform stress distribution, minimizing the risk of strip-out in thin-gauge metals. Their high corrosion resistance ensures long-term reliability in moist or chemical-exposed settings, reducing maintenance costs and downtime.
