S-93406A256 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 Stainless Steel construction, extending service life and reducing replacement costs.
• Enhanced load distribution and vibration resistance from the wide truss head design, minimizing the risk of material damage and loosening.
• High-torque driving capability with the Phillips No. 2 drive, ensuring efficient installation and reducing tool slippage.
• Secure, permanent fastening in sheet metal using thread forming technology, which creates strong threads without generating chips.
• Full-length threading for maximum grip and holding power along the entire 1-1/4" length, providing reliable performance.
• Simplified installation process with a pointed tip and specified No. 21 drill bit (0.159" diameter), ensuring precise alignment and fit.
• Compliance with stringent environmental regulations including RoHS 3 and REACH, ensuring safety and sustainability for industrial use.

Professional Applications & Engineering Value

This No. 10-12 x 1-1/4" 316 Stainless Steel Phillips Truss Head Tapping Screw is engineered to address common challenges in sheet metal fabrication, such as corrosion from moisture, chemicals, and outdoor exposure. The thread forming (A/AB type) tapping method displaces material to form strong, precise internal threads, eliminating chip production and providing excellent resistance to vibration loosening. Its wide truss head offers a larger bearing surface, distributing clamp load effectively to prevent sheet distortion and pull-through in thin materials up to 0.025" thick. The combination of fully threaded design and Phillips No. 2 drive ensures quick, reliable installations in assembly lines, HVAC systems, and electronic enclosures, enhancing productivity and long-term joint integrity.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.19" and approximately 12 threads per inch. It is a right-hand threaded, fully threaded, thread-forming tapping screw (Type A/AB) designed for use with a No. 21 drill bit (0.159" diameter). The product is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting rigorous environmental and safety standards for industrial components.
