Hex flange bolt & nut;GT3

Meet the GT3 Hex Flange Bolt & Nut—a purpose-built fastening duo designed to simplify assemblies where dependable clamping and surface protection matter. This paired bolt-and-nut set combines a hex flange bolt with a matching flange nut, delivering a complete, ready-to-use solution for quick, secure installations.

Why GT3 stands out

• 
  Integrated flange for even load distribution: The built-in flange seats flush against the surface, spreading clamping force over a larger area to minimize surface damage and maintain joint integrity.
• 
  One-piece assembly mindset: With a matching nut, you get a clean, washerless installation that speeds up setup and reduces the number of loose parts in your toolbox.
• 
  Broad tool compatibility: The hex head accepts common wrenches and sockets, making it easy to tighten in tight spaces or on busy shop floors.
• 
  Series consistency: GT3 designation ensures consistent thread engagement and seating across the entire product line, simplifying replacements and replenishment.
• 
  Versatile use cases: Ideal for automotive brackets, machinery frames, equipment housings, and DIY projects where vibration, heat, and load demands require reliable fasteners.

How to use

• Choose the correct thread size and length to fit your parts.
• Align components, start the bolt by hand to ensure a clean thread engagement, then tighten with the appropriate tool until the flange sits flush against the surface.
• Torque to the recommended specification for your application, and periodically re-torque after vibration or thermal cycles.

Maintenance and care: Regular inspection helps prevent loosening or fatigue. In high-vibration environments, re-check fasteners during routine maintenance to keep assemblies secure.
