S-90065A201 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability in sheet metal assemblies.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• Maximum holding power from the fully threaded shank, ensuring a secure, vibration-resistant fastening in materials up to 0.025" thick.
• Clean, flush installation with a standard 82° flat head and countersink angle, providing a smooth surface finish and preventing snagging.
• Reliable drive engagement using a No. 2 Phillips drive, minimizing cam-out and allowing for consistent torque application during assembly.
• Precision fit and compatibility with a No. 29 drill bit (0.136" diameter), ensuring accurate pilot holes and reducing the risk of material damage.
• Compliance with environmental and safety standards including RoHS 3 and REACH, making them suitable for regulated industrial and international markets.

Professional Applications & Engineering Value

This Type A thread forming screw is engineered specifically for sheet metal applications, where its 18-8 stainless steel composition provides excellent resistance to rust and corrosion, extending service life in demanding conditions. The thread forming (tapping) method displaces material to create strong, clean internal threads without generating chips, which is critical in thin-gauge metals to prevent weakening. The fully threaded design and pointed tip ensure easy starting and deep penetration, delivering superior pull-out strength and vibration resistance in assemblies like HVAC ductwork, electronic enclosures, and automotive panels. The flat head with 82° countersink sits flush, maintaining aerodynamic and aesthetic profiles while the Phillips drive offers widespread tool compatibility for efficient high-volume installation.

Specification Summary & Compliance

This screw meets standard dimensional requirements for a No. 8-15 thread (0.164" diameter, 15 threads per inch) with a 1-1/4" length and is manufactured as a Type A tapping screw per relevant industrial specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and safe for use in various industrial and consumer products.
