S-99512A525 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in industrial environments.
• Superior torque transmission and reduced cam-out thanks to the Torx Plus IP30 drive, allowing for high-tightening forces and efficient assembly.
• Secure, vibration-resistant fastening in plastics through the TRS thread forming design, which creates strong threads without pre-drilled tapping.
• Optimized grip and reduced material stress with the Tri-Lobe shank cross-section, minimizing the risk of stripping in plastic applications.
• Easy alignment and consistent seating provided by the rounded pan head profile, ensuring flush installation and professional finishes.
• Reliable partial threading for precise engagement control, preventing over-tightening and material damage in plastic assemblies.
• Compliance with global environmental standards, including RoHS 3 and REACH, making these screws suitable for regulated industries.

Professional Applications & Engineering Value

These 1/4" zinc-plated steel tapping screws are engineered to address common challenges in plastic fastening, such as material cracking and thread stripping. The TRS thread forming design eliminates the need for separate tapping operations by cold-forming threads directly into plastic substrates, reducing assembly time and enhancing joint integrity. Combined with the Torx Plus IP30 drive, these screws deliver maximum torque transfer, minimizing tool slippage and improving operator efficiency in high-volume production. The Tri-Lobe shank and blunt tip facilitate smooth insertion, while the zinc plating offers durable protection against corrosion, making these fasteners ideal for automotive, electronics, and appliance manufacturing where precision and durability are critical.

Specification Summary & Compliance

This product features a 1/4" diameter with approximately 10 threads per inch and a right-hand thread direction, conforming to standard inch measurements. The partially threaded design ensures controlled engagement, and the screw is manufactured for use with plastic materials, recommended with drill bit size A (0.234" diameter). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial applications.
