S-93406A209 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction for long-lasting performance in harsh industrial environments
• Efficient thread forming technology eliminates need for separate tapping operations, reducing installation time and labor costs
• Enhanced load distribution with wide truss head design that prevents pull-through in thin sheet metal applications
• Secure fastening in materials up to 0.025" thickness with fully threaded design and pointed tip for immediate engagement
• Reliable Phillips drive system (No. 2 size) provides consistent torque transfer and prevents cam-out during installation
• Precision threading with 15 threads per inch ensures tight, vibration-resistant connections in sheet metal assemblies
• Compliance with environmental regulations including RoHS 3 and REACH for safe use in regulated industries

Professional Applications & Engineering Value

These 316 stainless steel tapping screws deliver exceptional value in sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology creates strong, permanent threads in pre-drilled holes without generating chips, making them ideal for electrical enclosures, HVAC systems, and metal fabrication where debris contamination must be avoided. The wide truss head design provides superior clamping force distribution, preventing material deformation in thin-gauge metals up to 0.025" thickness. With their fully threaded configuration and pointed tip, these Phillips drive screws ensure immediate engagement and consistent holding power throughout the entire fastener length, reducing the risk of joint failure in vibration-prone environments.

Specification Summary & Compliance

These No. 8 x 1-1/2" tapping screws feature precision 0.164" thread diameter with 15 threads per inch in right-hand direction, manufactured to A/AB tapping screw standards for consistent performance. The screws are designed for use with No. 29 drill bit (0.136" diameter) and comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial safety and substance restriction requirements for professional use.
