S-90203A515 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in demanding industrial environments
• Efficient installation through self-drilling No. 2 tip that eliminates pre-drilling requirements in materials up to 0.098" thickness
• Exceptional holding power with BSD thread forming technology that creates stronger, more reliable connections in steel and sheet metal
• Secure fastening with fully threaded design that maximizes engagement and prevents loosening under vibration
• Enhanced torque transmission through square drive design that reduces cam-out and ensures proper installation
• Regulatory compliance with RoHS 3 and REACH standards for environmentally responsible manufacturing and global market acceptance
• Versatile application in steel, stainless steel, and sheet metal with right-hand thread direction and standard pan head profile

Professional Applications & Engineering Value

This No. 8-18 x 1-1/4" tapping screw delivers exceptional engineering value through its 410 stainless steel composition and advanced BSD thread forming technology. The integrated No. 2 drilling tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs in steel, stainless steel, and sheet metal applications. The thread forming action creates stronger, more vibration-resistant connections by displacing material rather than removing it, resulting in superior pull-out resistance. The fully threaded design ensures maximum engagement throughout the fastener length, while the square drive provides reliable torque transmission without stripping. These features combine to solve critical industrial challenges including assembly efficiency, joint reliability, and corrosion resistance in demanding environments.

Specification Summary & Compliance

This tapping screw features precision No. 8-18 thread specifications with 0.164" thread diameter and 18 TPI right-hand threading. The fastener maintains BSD thread forming standards with fully threaded design and Class 2A thread tolerances for consistent performance. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and market acceptance. The screw is engineered for use in steel, stainless steel, and sheet metal applications with maximum drilling capacity of 0.098" thickness.
