S-93035A342 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Reliable Sealing Performance: Built-in rubber O-ring creates a durable seal in sheet metal applications, preventing leaks and contamination in demanding environments.
• Corrosion-Resistant Durability: Made from 18-8 Stainless Steel for excellent resistance to rust and corrosion, ensuring long-term reliability in various industrial conditions.
• Efficient Thread-Forming Installation: B-type thread-forming design with a blunt tip taps its own threads, reducing assembly time and providing secure, vibration-resistant fastening without pre-tapping.
• Wide Temperature Tolerance: O-ring maintains sealing integrity across a broad temperature range from -40° to 225° F, suitable for both cold and high-heat applications.
• User-Friendly Drive System: Phillips pan head with No. 1 drive size offers comfortable, secure driving and a low-profile, rounded head for a clean finish.
• Full Thread Engagement: Fully threaded shank ensures maximum grip and uniform stress distribution along the entire 5/8" length in sheet metal substrates.
• Environmental & Regulatory Compliance: Meets RoHS 3 and REACH standards, ensuring safe, eco-friendly use in global industrial supply chains.

Professional Applications & Engineering Value

This No. 4-24 tapping screw is engineered to address common challenges in sheet metal assembly, such as fluid ingress and vibration loosening. The thread-forming B-type design with a 0.112" thread diameter and 24 threads per inch creates precise, strong threads in pre-drilled holes (using a No. 44 drill bit), eliminating the need for separate tapping operations and reducing labor costs. The integrated rubber O-ring provides a reliable seal against moisture, dust, and chemicals, while the 18-8 Stainless Steel construction offers corrosion resistance for outdoor or harsh environments. Ideal for HVAC, automotive, and electronics enclosures, this screw ensures leak-proof, secure fastening that withstands thermal cycling and mechanical stress, enhancing product longevity and reducing maintenance.

Specification Summary & Compliance

This screw features a No. 4-24 thread size with a 5/8" length, fully threaded shank, and Phillips pan head (No. 1 drive). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use. The thread-forming design follows typical inch-system tolerances for reliable performance in sheet metal applications.
