S-90065A077 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time.
• Optimal flush mounting with standard flat head profile and 82° countersink angle for smooth, secure surface finishes.
• Enhanced driving control provided by Phillips No. 1 drive, minimizing cam-out and improving torque transfer.
• Full threading along the 1/4" length maximizes grip strength and distributes load evenly across the fastened materials.
• Right-hand threading with 32 TPI delivers fine pitch engagement for precise fastening in thin sheet metal applications.
• Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible use in industrial settings.

Professional Applications & Engineering Value

This No. 2-32 x 1/4" tapping screw is specifically engineered for sheet metal applications, where material integrity and fastener durability are critical. The 18-8 stainless steel composition offers excellent resistance to rust and corrosion, making it ideal for outdoor equipment, HVAC systems, and electronic enclosures exposed to moisture. Its thread forming (Type A) design eliminates the need for separate tapping operations, as the screw cold-forms mating threads directly into pre-drilled holes (using a No. 48 drill bit), reducing assembly steps and preventing metal chip accumulation. The fully threaded shank and pointed tip ensure quick starts and consistent holding power, even in thin gauges up to 0.025". Combined with the Phillips flat head, it provides a low-profile, vibration-resistant connection that maintains structural stability under dynamic loads.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.086" and 32 threads per inch (TPI), ensuring precise fit in accordance with common tapping screw specifications. The flat head features an 82° countersink angle for flush seating, and the fully threaded, right-hand design follows industrial norms for ease of installation. Manufacturing and material compliance include RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of restricted substances and supporting use in regulated sectors.
