S-90410A109 10-24 x 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction, ideal for harsh industrial environments and long-term reliability.
• Efficient self-tapping installation with Type F thread cutting design, eliminating the need for pre-tapped holes in brass, cast iron, and sheet metal.
• Enhanced driving control provided by the Phillips No. 2 drive and pan head, reducing cam-out and ensuring secure, flush fastening.
• Maximum holding power from fully threaded UNC coarse threads, delivering robust, vibration-resistant connections in various materials.
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting strict environmental and safety requirements for global supply chains.
• Optimized for high-volume assembly with standardized 10-24 thread size and 1-1/2" length, ensuring compatibility and speeding up production workflows.
• Precision drilling guidance with recommended No. 25 drill bit (0.1495" diameter), minimizing installation errors and material stress.

Professional Applications & Engineering Value

These 410 stainless steel tapping screws are engineered to address common challenges in metal fabrication and assembly, such as material fatigue and corrosion-induced failure. The Type F thread cutting design and UNC coarse thread profile enable quick, secure fastening in brass, cast iron, and sheet metal without pre-tapping, reducing labor time and tooling costs. The Phillips drive and pan head offer reliable torque transmission and a low-profile finish, ideal for applications where space is constrained. Made from durable 410 stainless steel, these screws resist oxidation and chemical exposure, extending service life in industrial settings like HVAC systems, automotive components, and machinery enclosures. Their full threading ensures even load distribution, preventing loosening under dynamic stresses.

Specification Summary & Compliance

This product adheres to UNC coarse thread standards with a 10-24 size and right-hand thread direction, ensuring dimensional accuracy for Class 2A fit. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. The screws are fully threaded with a blunt tip and round shank cross-section, designed for use with a No. 25 drill bit (0.1495" diameter) to achieve optimal thread engagement and pull-out strength in specified materials.
