S-93195A435 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Efficient thread forming action creates strong, permanent threads in sheet metal without pre-tapped holes
• Optimal flush mounting with standard 82° flat head profile that sits perfectly countersunk in materials
• Reliable driving performance through Phillips No. 2 drive system that resists cam-out during installation
• Full-length threading ensures maximum grip strength and uniform load distribution along the entire fastener length
• Precision installation compatibility with standard No. 29 drill bit (0.136") for accurate hole preparation
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe industrial use

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional value in sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming Type B design eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that won't loosen under stress. The Phillips flat head configuration with 82° countersink angle provides a clean, flush finish that prevents snagging while maintaining aerodynamic surfaces. Engineered with fully threaded blunt tips, these screws distribute clamping force evenly across the entire engagement length, preventing material distortion in thin-gauge metals. The combination of 18 TPI fine threading and 0.164" thread diameter ensures secure fastening in various metal thicknesses, making them ideal for HVAC systems, electronic enclosures, and industrial equipment assembly.

Specification Summary & Compliance

This No. 8-18 x 1" tapping screw features precision thread forming technology with standard inch measurements including 0.312" head diameter, 0.164" thread diameter, and 18 threads per inch. Manufactured to industry standards for flat head profile with 82° countersink angle and Phillips No. 2 drive compatibility. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial applications. The right-hand threaded, fully threaded design provides consistent performance in sheet metal fastening applications when used with recommended No. 29 drill bit preparation.
