S-90077A317 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Enhanced torque transfer and reduced tool slippage through the dual Phillips/Slotted drive design for reliable, efficient installation.
• Strong, secure fastening in sheet metal using thread-forming technology that creates precise, durable threads without pre-tapping.
• Versatile pan head design with a rounded profile provides a low-profile, flush finish while distributing clamping force evenly.
• Full threading along the 1-1/2" length ensures maximum grip and uniform stress distribution across the entire fastened joint.
• Optimized for 0.025" maximum drilling thickness, delivering precise performance in standard sheet metal applications with minimal material displacement.
• Compliance with RoHS 3 and REACH regulations guarantees safety and environmental responsibility for global industrial use.

Professional Applications & Engineering Value

These No. 14 zinc-plated steel tapping screws are engineered to address common challenges in sheet metal assembly, such as thread stripping and corrosion-induced failure. The thread-forming A/AB type design displaces material to create strong, clean threads without chips, reducing the risk of loose connections in thin-gauge metals. With a 0.242" thread diameter and 10 threads per inch, the screw maintains consistent engagement, while the pan head and Phillips/Slotted drive allow for high-torque installation using standard tools. Ideal for HVAC, automotive, and electronics enclosures, these screws provide reliable, vibration-resistant fastening that withstands industrial stresses, backed by RoHS 3 and REACH compliance for safe, sustainable operations.

Specification Summary & Compliance

This tapping screw adheres to standard inch measurements, featuring a No. 14 size, 1-1/2" length, and fully threaded right-hand configuration with a pointed tip for easy starting. Thread specifications include a 0.242" diameter and 10 threads per inch, compatible with a 5.5 mm drill bit for precise hole preparation. Manufacturing follows industry-accepted tolerances for thread-forming screws, and the product is verified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to environmental and safety standards in industrial applications.
