Hex and toxy screwdriver 14pcs

It sounds like you’re referring to a Hex screwdriver and a Torx screwdriver. The term “Toxy” is likely a phonetic spelling of “Torx.” Both are popular types of screwdrivers designed to fit specific fastener head shapes.

Here’s a breakdown of each:

1. Hex Screwdriver (or Hex Key / Allen Wrench)

• Shape: The fastener head has a six-sided (hexagonal) recess (a hole shaped like a hexagon).
• Driver: The screwdriver bit or tool has a matching six-sided hexagonal shape that fits snugly into this recess.
• Common Names: Often referred to as Allen wrenches or Allen keys, named after the original manufacturer. They typically come in L-shaped tools (Allen keys) or as straight bits for a screwdriver handle or power drill.
• Advantages:
  • Good torque transfer: The six contact points allow for a decent amount of turning force to be applied.
  • Recessed head: Allows screws to be flush with the surface, which is aesthetically pleasing and prevents snagging.
  • Compact tools: L-shaped hex keys are simple, small, and lightweight.
• Disadvantages: Can be prone to “rounding out” or stripping the recess if the wrong size is used, the tool is worn, or too much force is applied. Also, they can “cam-out” (the driver slipping out of the fastener head) under high torque.
• Common Uses:
  • Furniture assembly (especially flat-pack furniture like IKEA)
  • Bicycles
  • Automotive components
  • Machinery and equipment
  • Set screws (screws with no head, often used to secure objects to shafts)

2. Torx Screwdriver (or Star Screwdriver)

• Shape: The fastener head has a six-point star-shaped recess.
• Driver: The screwdriver bit has a corresponding six-point star shape.
• Common Names: Also known as star drivers or star bits.
• Sizing: Torx sizes are designated with a “T” followed by a number (e.g., T10, T25, T40).
• Advantages:
  • Excellent torque transfer: The star shape allows for significantly higher torque to be applied compared to Phillips or even Hex heads of similar size, with very little risk of stripping the head or damaging the tool.
  • Reduced cam-out: The geometry is specifically designed to minimize the tendency of the driver to slip out of the screw head, leading to more efficient and secure tightening.
  • Longer tool life: Less wear on both the fastener and the driver due to better engagement.
• Disadvantages: Requires a specialized Torx driver; a standard flat-head, Phillips, or Hex screwdriver will not work.
• Common Uses:
  • Automotive industry: Widely used due to high torque requirements and resistance to vibration.
  • Electronics and computers: Laptops, hard drives, gaming consoles, smartphones, and various other consumer electronics.
  • Appliances
  • Security applications: A variation called Security Torx (or Tamper-Resistant Torx) has a small pin in the center of the star recess, requiring a driver with a corresponding hole. This prevents unauthorized access.
