S-95638A325 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments and reducing replacement costs.
• Enhanced security and tamper resistance with the T10 Torx drive, deterring unauthorized removal and maintaining assembly integrity.
• Efficient thread forming design (Type A/AB) creates strong, permanent threads in sheet metal, eliminating the need for pre-tapped holes and speeding up installation.
• Optimized for thin sheet metal up to 0.025" thickness, providing secure fastening without material deformation or stripping.
• Full threading and pointed tip enable quick, self-starting engagement and consistent holding power across the entire 3/8" length.
• Precision dimensional accuracy with No. 6-20 thread and 0.138" diameter, ensuring reliable fit and performance in standardized applications.
• Simplified installation process using a standard 7/64" drill bit, reducing setup time and tooling requirements for maintenance teams.

Professional Applications & Engineering Value

This No. 6-20 thread forming screw is engineered to address common challenges in sheet metal fabrication, such as material splitting and loose fasteners under vibration. The 18-8 stainless steel composition provides excellent resistance to rust and chemical exposure, making it ideal for outdoor enclosures, HVAC systems, and electrical cabinets. Its tamper-resistant Torx T10 drive adds a layer of security for public infrastructure or sensitive equipment, while the fully threaded design and pointed tip ensure rapid penetration and high clamp force in metals up to 0.025" thick. By eliminating the need for nuts or washers, this A/AB tapping screw streamlines assembly lines and reduces total installed cost in high-volume production environments.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a No. 6-20 thread (0.138" diameter, 20 TPI) and Class 2A tolerance for consistent fit. It conforms to thread forming specifications for Type A/AB tapping screws, with a right-hand thread direction and fully threaded 3/8" length. The manufacturing process complies with industry standards for dimensional accuracy, and the 18-8 stainless steel material meets RoHS and REACH requirements for environmental safety.
