S-93035A433 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior leak prevention with an integrated rubber O-ring that maintains a reliable seal across a wide temperature range from -40°F to 225°F, ideal for demanding industrial environments.
• Excellent corrosion resistance due to 18-8 Stainless Steel construction, ensuring long-term durability and reliability in humid or corrosive conditions.
• Efficient thread-forming installation with a Type B blunt tip that creates strong, precise threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Secure and stable fastening provided by a fully threaded shank and pan head design, distributing clamp load evenly for a vibration-resistant hold.
• Streamlined installation process using a standard Phillips No. 2 drive, allowing for quick, high-torque application with common tools and minimizing cam-out risks.
• Regulatory peace of mind with full compliance to RoHS 3 and REACH standards, ensuring the screw is free from hazardous substances for safe use in regulated industries.
• Optimized for sheet metal applications with a recommended No. 32 drill bit (0.116" diameter), ensuring a perfect fit and maximum thread engagement for robust assemblies.

Professional Applications & Engineering Value

This 18-8 Stainless Steel tapping screw is engineered to address critical challenges in sheet metal assembly, where leak prevention and corrosion resistance are paramount. The thread forming design, combined with a blunt tip and Type B threading, eliminates the need for separate tapping operations, reducing production steps and potential errors. The integrated rubber O-ring provides a dependable seal against moisture, dust, and air ingress, making it ideal for HVAC systems, electronic enclosures, and outdoor equipment. Its Phillips pan head ensures a low-profile, secure fit that withstands vibrations, while the fully threaded shank enhances grip strength in thin materials. By leveraging these features, engineers can achieve faster assembly cycles, lower lifecycle costs, and enhanced product reliability in demanding applications.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.138" and 20 threads per inch, ensuring precise fit in pre-drilled holes (recommended No. 32 drill bit, 0.116" diameter). The right-hand thread and Class 2A threading tolerance provide consistent engagement and ease of installation. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for safe industrial use.
