S-94155A099 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs
• Secure square drive engagement with No. 1 drive size prevents cam-out and ensures reliable installation torque transfer
• Optimized for thin materials with maximum drilling thickness of 0.025" and pointed tip for precise penetration in sheet metal applications
• Pan head design provides a low-profile finish with good bearing surface for secure fastening without sinking
• Full threading along the entire 3/8" length ensures maximum grip and holding power throughout the material thickness
• Environmental compliance with RoHS 3 and REACH regulations for safe use in regulated industries and global markets

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations, creating strong, strip-resistant threads that maintain integrity under vibration and load. The A/AB screw type with right-hand threading and 18 TPI pitch provides optimal bite in thin gauge materials, while the pan head configuration with No. 1 square drive ensures positive driver engagement without slippage. Ideal for HVAC systems, electronic enclosures, and automotive components where corrosion resistance and reliable fastening in 0.025" maximum thickness materials are critical engineering requirements.

Specification Summary & Compliance

This No. 6-18 x 3/8" tapping screw features precise 0.138" thread diameter with 18 threads per inch and fully threaded shank design. Manufactured to thread forming standards for A/AB type sheet metal screws, it requires No. 32 drill bit (0.116" diameter) for proper installation. The screw complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring material safety and regulatory compliance for industrial applications worldwide.
