S-93880A197 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Maximum torque application capability through combined external hex/slotted drive design for secure installation and removal
• Eliminates the need for separate washers with integrated flange design that distributes load evenly and prevents pull-through
• Exceptional holding power in sheet metal achieved through thread forming technology that creates strong, permanent threads without chips
• Full-length threading ensures maximum engagement and superior fastening strength throughout the entire length
• Simplified installation process with precise No. 29 drill bit (0.136") compatibility for consistent, reliable hole preparation
• Environmentally responsible manufacturing with RoHS 3 compliance for sustainable procurement and regulatory peace of mind

Professional Applications & Engineering Value

Engineered specifically for sheet metal applications, these No. 8-18 x 3/4" zinc-plated steel tapping screws deliver exceptional performance where traditional fasteners fail. The thread forming Type B design creates strong, permanent threads in base materials without generating chips, eliminating contamination risks in sensitive assemblies. The combination of external hex/slotted drive provides versatile installation options while maintaining high torque resistance. The integrated flange design eliminates the need for separate washers, reducing component count and installation time. These fully threaded screws with 0.164" thread diameter and 18 threads per inch ensure maximum material engagement, making them ideal for HVAC systems, electrical enclosures, and automotive panels where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

This No. 8-18 x 3/4" tapping screw features precise inch system dimensions with Class 2A thread tolerances for consistent performance. The thread forming Type B design follows industry-standard specifications for sheet metal fastening applications. Manufacturing complies with RoHS 3 (2015/863/EU) environmental standards, ensuring restricted substance compliance for global industrial use. The screw requires a No. 29 drill bit (0.136" diameter) for proper hole preparation and features right-hand threading with blunt tip configuration for controlled installation in various sheet metal thicknesses.
