S-93406A071 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and long-term reliability.
• Enhanced load distribution from the wide truss head design, reducing surface damage and preventing pull-through in thin sheet metal.
• Efficient thread-forming installation with pointed tip and 32 threads per inch, ensuring strong, vibration-resistant fastening without pre-tapping.
• Secure, cam-out resistant driving using a No. 1 Phillips drive, providing consistent torque application and reducing tool slippage.
• Full threading for maximum grip along the entire 1/4" length, delivering uniform clamping force in sheet metal assemblies.
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries and global markets.

Professional Applications & Engineering Value

These No. 2 Phillips Truss Head Tapping Screws are precision-engineered for demanding sheet metal applications, where material integrity and fastener reliability are critical. The 18-8 stainless steel offers excellent resistance to oxidation and corrosion, extending service life in HVAC, electronics enclosures, and automotive assemblies. The thread-forming (A/AB type) design with a pointed tip allows for easy, self-tapping installation into pre-drilled holes (No. 48 drill bit, 0.076" diameter), eliminating the need for separate tapping operations and reducing assembly time. The wide truss head profile distributes clamping force over a larger area, minimizing the risk of sheet deformation or fatigue under dynamic loads. This combination of high-strength materials and optimized geometry ensures secure, long-lasting fastening in thin-gauge metals, supporting efficient production and reduced maintenance cycles.

Specification Summary & Compliance

These screws feature a thread diameter of 0.086" with 32 threads per inch, designed for thread-forming (Type A/AB) applications in materials up to 0.025" thickness. Manufactured to standard inch dimensions with a fully threaded, right-hand thread direction and No. 1 Phillips drive for consistent performance. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring adherence to environmental and safety regulations for industrial use.
