S-90184A050 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor applications
• Superior thread-forming capability creates strong, permanent threads in sheet metal without pre-tapping requirements
• Optimized Phillips No. 1 drive provides secure tool engagement and reduces cam-out during installation
• Maximum holding power achieved through 32 TPI fine threading and full-length thread engagement
• Streamlined installation process with pointed tip design that self-starts in pre-drilled No. 48 holes
• Reliable performance in thin materials with capability to fasten sheet metal up to 0.025" thickness
• Industry compliance assurance meeting RoHS 3 and REACH environmental standards for global applications

Professional Applications & Engineering Value

These 316 stainless steel thread forming screws deliver exceptional value in sheet metal applications where corrosion resistance and vibration resistance are critical. The Phillips pan head design combines easy installation with a low-profile finish, while the thread forming technology eliminates the need for separate tapping operations, reducing assembly time and labor costs. The fully threaded construction ensures maximum pull-out strength in thin-gauge materials commonly used in HVAC systems, electronic enclosures, and industrial equipment. The corrosion-resistant properties of 316 stainless steel make these tapping screws ideal for marine environments, chemical processing facilities, and outdoor installations where moisture and corrosive elements are present.

Specification Summary & Compliance
