S-90184A378 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and outdoor applications.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Reliable drive engagement with Phillips No. 2 drive style, providing secure torque transmission and minimizing cam-out during installation.
• Optimized for sheet metal applications with a maximum drilling thickness of 0.025", ensuring secure fastening in thin materials.
• Full threading and pointed tip for easy starting and consistent holding power along the entire 1" length.
• Standard pan head profile offers a low-profile, rounded finish that sits flush and resists snagging.
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in industrial and consumer products.

Professional Applications & Engineering Value

These 316 Stainless Steel thread forming tapping screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion. The thread forming (Type A/AB) design displaces material rather than cutting it, resulting in stronger threads with improved resistance to vibration loosening. The Phillips pan head with a No. 2 drive size ensures compatibility with standard tools, facilitating quick assembly in high-volume production. Made from 316 Stainless Steel, these screws provide exceptional durability in corrosive environments, including marine, chemical processing, and outdoor enclosures, reducing maintenance costs and extending service life. The fully threaded, pointed tip allows for easy alignment and penetration, making them ideal for HVAC systems, electronic chassis, and automotive panels where reliability is critical.

Specification Summary & Compliance

This No. 10-12 x 1" tapping screw features a thread diameter of 0.19" with approximately 12 threads per inch, a head diameter of 0.373", and a pan head height of 0.133". It is designed for use with a No. 21 drill bit (0.159" diameter) and complies with standard thread forming specifications for sheet metal. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial applications.
