S-99512A673 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T25 Torx drive design, reducing cam-out risk and tool wear during installation
• Exceptional pull-out resistance thanks to tri-lobe shank design that creates secure, vibration-resistant threads in plastic materials
• Enhanced corrosion protection from black-oxide steel finish, extending service life in demanding plastic assembly environments
• Optimized plastic fastening with thread forming (TRS) design that eliminates chip formation and prevents material damage
• Consistent driving performance with fully threaded blunt tip design for uniform stress distribution and reliable seating
• Broad compatibility with standard No. 15 drill bits (0.18" diameter) for simplified installation processes
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for global manufacturing applications

Professional Applications & Engineering Value

These No. 10-14 thread forming screws are specifically engineered to address common challenges in plastic assembly applications where material integrity and joint reliability are critical. The tri-lobe shank design displaces plastic material during installation, creating permanent, high-strength threads without generating chips that could compromise electronic components or contaminate clean environments. The T25 Torx drive system provides superior torque transfer compared to traditional drive types, minimizing strip-out incidents and ensuring consistent clamp load in production settings. Manufactured from black-oxide coated steel, these plastic tapping screws offer excellent corrosion resistance while the pan head design provides a low-profile, aesthetically pleasing finish. Ideal for automotive trim, electronics enclosures, and consumer products where vibration resistance and long-term fastening integrity are essential.

Specification Summary & Compliance

These TRS plastic tapping screws feature No. 10-14 thread configuration with Class 2A tolerance, right-hand thread direction, and full threading along the 1/2" length. The tri-lobe shank cross-section conforms to standard thread forming screw specifications for plastic applications. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. The black-oxide surface treatment provides consistent corrosion protection while maintaining dimensional accuracy for reliable performance in automated assembly systems.
