S-93406A008 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 demanding environments.
• Enhanced load distribution from the wide truss head design, reducing the risk of material pull-through in thin sheet metal.
• Efficient thread forming technology creates strong, secure threads without pre-tapping, speeding up assembly and reducing labor costs.
• Full threading along the entire 1/4" length provides maximum grip and holding power in sheet metal applications.
• Precision compatibility with No. 55 drill bits (0.052" diameter) and up to 0.025" material thickness, ensuring accurate, hassle-free installations.
• Secure, slip-resistant drive with the Phillips No. 0 style, allowing for consistent torque application and reduced tool cam-out.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe, sustainable use in regulated industries.

Professional Applications & Engineering Value

These No. 0 Phillips Truss Head tapping screws are engineered specifically for sheet metal assemblies, where material integrity and fastener reliability are critical. The 18-8 stainless steel offers excellent resistance to rust and oxidation, ideal for outdoor or humid conditions. The thread forming (Type A/AB) design displaces material to form strong internal threads, eliminating the need for separate tapping operations and reducing assembly time. The wide truss head distributes clamping force over a larger area, preventing deformation in thin-gauge metals. This combination of fully threaded shanks and pointed tips ensures quick starts and secure fastening in applications like HVAC ductwork, electronic enclosures, and automotive panels, enhancing structural stability and longevity.

Specification Summary & Compliance

This screw features a No. 0 size with a right-hand thread direction, 52 threads per inch, and a 1/4" length. It conforms to standard inch measurements and is designed for use with a No. 55 drill bit (0.052" diameter) in materials up to 0.025" thick. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for industrial use.
