S-90190A054 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in industrial environments.
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and tooling needs.
• Optimized for thin materials with a maximum drilling thickness of 0.025", providing reliable fastening in delicate sheet metal applications.
• Enhanced drive stability from the Phillips No. 0 drive and rounded pan head design, minimizing cam-out and improving torque application.
• Full threading along the 3/8" length ensures maximum grip and uniform stress distribution for secure, vibration-resistant joints.
• Precision thread geometry with 0.073" diameter and 48 TPI delivers tight, secure fits that resist loosening under stress.
• Compliance with RoHS 3 standards guarantees environmentally safe materials, meeting global regulatory requirements for industrial use.

Professional Applications & Engineering Value

These No. 1 Phillips pan head tapping screws are engineered to address common challenges in sheet metal assembly, such as material splitting and thread stripping. The thread forming design displaces material rather than cutting it, creating stronger threads with improved fatigue resistance in thin-gauge metals. Made from zinc-plated steel, they offer excellent durability against corrosion, extending service life in HVAC, electronics enclosures, and automotive panels. The fully threaded shank and pointed tip facilitate quick starts, reducing installation time and labor costs while maintaining consistent clamping force. Ideal for high-volume production lines, these screws ensure reliable performance where precision and repeatability are critical.

Specification Summary & Compliance

This tapping screw adheres to Class 2A thread tolerances with a 0.073" thread diameter and 48 TPI, ensuring precise fit in pre-drilled holes using a No. 52 drill bit (0.0635" diameter). Manufactured as A/AB type thread forming screws with right-hand threading, they comply with RoHS 3 (2015/863/EU) regulations, confirming the absence of hazardous substances for safe industrial use.
