Pan head screw

Pan head screws, also referred to as hexalobular socket pan head screws or cheesehead screws, have a rounded, low-profile head and an internal Torx® drive that provides good torque transfer with reduced cam-out. 

The screws are used where reliable tightening, neat appearance and repeatable assembly are important. Typical applications include machinery, electrical equipment, automotive assemblies, and stainless steel fabrications and assemblies.  

BUMAX is an authorized manufacturer of the Torx® drive system, a registered product of Camcar Innovations®. BUMAX fasteners are produced with genuine Torx® and Torx Plus® drive systems, ensuring the highest fastener performance and quality.

Torx® drive systems provide greater tool and lobe engagement depth while minimizing tool slippage. Advantages include:

• Optimum torque transmission to support accurate clamp load.
• No cam-out forces pushing the driver up.
• Minimal end load is required since cam-out is virtually eliminated.
• High torque transfer and reduced radial forces resulting in longer tool life.
• Drive force spread over a broader surface.
