S-93406A040 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 industrial environments.
• Enhanced load distribution from the wide truss head design, reducing the risk of material damage and improving holding power in sheet metal.
• Efficient installation with the Phillips No. 0 drive, providing secure torque transfer and minimizing cam-out during assembly.
• Reliable thread engagement through thread forming technology, creating strong, vibration-resistant fastenings without pre-tapping.
• Precision fit for thin materials, optimized with a No. 52 drill bit (0.0635") for maximum drilling thickness up to 0.025", ensuring accurate placement.
• Full threading for consistent grip along the entire 1/4" length, offering uniform clamping force in sheet metal applications.
• Compliance with environmental standards, meeting RoHS 3 and REACH regulations for safe, sustainable use in global supply chains.

Professional Applications & Engineering Value

This No. 1-48 x 1/4" tapping screw is engineered to address common challenges in sheet metal assembly, such as material cracking and loosening under stress. The 18-8 stainless steel provides excellent durability against corrosion, while the thread forming method eliminates the need for separate tapping, reducing installation time and tooling costs. The wide truss head distributes pressure evenly, preventing pull-through in thin gauges, and the Phillips drive ensures quick, secure fastening. Ideal for HVAC, automotive, and electronics enclosures, this screw delivers consistent performance in precision-driven industries where vibration resistance and longevity are critical.
