S-90415A646 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Eliminate pre-drilling operations with the integrated steel drill tip that penetrates up to 0.177" thick steel, stainless steel, and sheet metal, saving time and labor costs.
• Superior corrosion resistance provided by the 18-8 stainless steel base material with corrosion-resistant coating, ensuring long-term reliability in harsh industrial environments.
• Maximum holding power and vibration resistance due to the fully threaded design and thread forming (BSD) tapping method, which creates strong, secure fastenings.
• Efficient and secure installation enabled by the Phillips No. 2 drive and rounded pan head, allowing for controlled torque and a flush, low-profile finish.
• Broad material compatibility for use in steel, stainless steel, and sheet metal applications, making it a versatile fastener for various industrial assembly tasks.
• Precision drilling performance with a No. 3 drill tip and 11/64" drill tip length, ensuring clean, accurate holes and reducing material stress.
• Compliance with international environmental and safety standards including RoHS 3 and REACH, ensuring the screws are safe for use in regulated industries and global markets.

Professional Applications & Engineering Value

This No. 10-16 x 1-1/4" self-drilling tapping screw is engineered to solve critical challenges in metalworking and industrial assembly. Its corrosion-resistant coated 18-8 stainless steel construction provides exceptional durability against moisture and chemicals, reducing maintenance needs in outdoor or corrosive settings. The thread forming (BSD) design and fully threaded shank ensure strong, reliable fastenings in steel, stainless steel, and sheet metal without requiring pre-tapped holes, which minimizes installation time and tooling costs. The Phillips drive and pan head offer easy, secure driving, while the integrated drill tip (No. 3 type) allows for precise, burr-free holes up to 0.177" thick, enhancing structural integrity and assembly efficiency in HVAC, automotive, and construction applications.
