S-99512A462 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with the Torx Plus IP25 drive, reducing cam-out and tool wear for efficient installation in plastic assemblies.
• Exceptional holding power in plastics due to the thread forming (TRS) design and Tri-Lobe shank, which creates secure, vibration-resistant fastenings without pre-drilled threads.
• Enhanced corrosion resistance from the zinc-plated steel material, ensuring long-term durability in various industrial environments.
• Full threading along the 1-1/4" length provides maximum grip and uniform stress distribution, ideal for high-stress plastic applications.
• Streamlined installation process with a blunt tip and compatibility with a No. 15 drill bit (0.18" diameter), minimizing preparation time and material cracking.
• Broad compliance with environmental regulations, including RoHS 3 and REACH, making these screws suitable for global supply chains and sensitive applications.

Professional Applications & Engineering Value

These No. 10 x 1-1/4" zinc-plated steel TRS tapping screws are engineered to address common challenges in plastic fastening, such as material stripping and loosening under vibration. The thread forming action and Tri-Lobe shank cross-section displace plastic material to form strong, permanent threads without chips, reducing the risk of stress cracks. Combined with the Torx Plus drive (IP25/T25), they enable higher torque application and minimize slippage, ensuring reliable performance in automotive trim, electronics enclosures, and consumer appliances. The zinc-plated finish provides a protective barrier against corrosion, extending service life in humid or outdoor conditions, while the pan head style offers a low-profile, secure fit for assembled components.

Specification Summary & Compliance

This No. 10 screw features a 1-1/4" length with fully threaded, right-hand direction and approximately 14 threads per inch. It adheres to standard inch measurements and is designed for use with a No. 15 drill bit (0.18" diameter). The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for industrial applications requiring environmental and safety standards.
