S-94209A710 1/4"-20 x 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-coated steel for extended service life in harsh environments
• Enhanced torque transmission via Torx Plus IP30 drive, reducing cam-out and tool wear
• Reliable thread forming in soft materials like aluminum, brass, and copper without pre-tapped holes
• Secure anti-rotation performance from Tri-Lobe shank design, preventing loosening under vibration
• Optimized coarse UNC threading for faster installation and strong holding power in coarse-grained materials
• Full 1" threading ensures maximum grip length and uniform stress distribution
• Compliance with RoHS 3 and REACH for safe, environmentally responsible industrial use

Professional Applications & Engineering Value

These 1/4-20 UNC Torx Plus tapping screws are engineered to address common assembly challenges in aluminum, brass, and copper components. The black corrosion-resistant coated steel construction protects against oxidation and chemical exposure, ideal for outdoor or high-moisture settings. With a thread forming design, they create strong, precise threads in ductile metals, eliminating the need for separate tapping operations and reducing installation time. The Tri-Lobe shank resists rotation, while the Torx Plus drive ensures high torque transfer without slippage, making them perfect for automated assembly lines and high-stress industrial applications where reliability is critical.

Specification Summary & Compliance

This screw features a 1/4"-20 UNC coarse thread with Class 2A tolerance, fully threaded up to 1" length (tolerance: -0.03" to 0"), and a standard pan head profile. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial fastener applications.
