S-90065A108 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 stainless steel construction ensures long-lasting performance in harsh industrial environments, reducing replacement costs and downtime.
• Thread forming (Type A) design creates strong, secure threads in sheet metal without pre-tapping, saving time and labor during assembly.
• Standard 82° flat head with Phillips drive provides a flush finish and reliable torque transfer, preventing cam-out and ensuring a neat appearance.
• Fully threaded shank offers maximum grip and holding power along the entire length for superior fastening in thin materials.
• Precise No. 4-24 thread with right-hand direction delivers consistent engagement and ease of installation in standard sheet metal applications.
• Compatible with No. 44 drill bit (0.086") simplifies hole preparation, ensuring accurate fit and reducing the risk of material damage.
• RoHS 3 and REACH compliance guarantees environmental safety and regulatory adherence for global industrial use.

Professional Applications & Engineering Value

This No. 4-24 x 3/8" Phillips flat head tapping screw is engineered to address common challenges in sheet metal fabrication, such as material stripping and corrosion. The 18-8 stainless steel provides excellent resistance to rust and oxidation, ideal for outdoor or humid conditions. Its thread forming technology (Type A) cold-forms threads directly into the metal, eliminating the need for separate tapping operations and reducing assembly time. The flat head with an 82° countersink sits flush to prevent snagging and improve aerodynamics in enclosures or panels. With a maximum drilling thickness of 0.025", it ensures secure fastening in thin-gauge materials, making it a reliable choice for HVAC systems, electronic chassis, and automotive components where durability and efficiency are critical.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a No. 4-24 thread size and 3/8" length, featuring a fully threaded, right-hand design for consistent performance. It meets industry tolerances for thread forming screws and includes a standard 82° countersink angle for proper seating. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) ensures it is free from hazardous substances, supporting safe and sustainable industrial applications.
