*USED* Cross recessed pan head flange carbon steel ST2.9x9 tapping screw

Meet the budget-friendly fastener that still delivers solid metal-assembly performance: the *USED* Cross recessed pan head flange carbon steel ST2.9x9 tapping screw. Designed for self-tapping in thin sheet metal, this screw is ideal for quick repairs, maintenance, and hobby projects where you need reliable fastening without paying for a brand-new part.

What makes this screw stand out:

• 
  Self-tapping capability—forms its own threads in compatible metal, streamlining assembly by eliminating the need for pre-tapping in many applications.
• 
  Flange under the head paired with a pan head design distributes clamping load over a larger area, reducing surface indentation and improving grip on panels and brackets.
• 
  Cross recessed (Phillips) drive provides dependable torque transfer and minimizes cam-out with common screwdrivers and power drivers.
• 
  Carbon steel construction balances strength and cost, making it a practical choice for everyday hardware tasks and bulk use.
• 
  Compact size — ST2.9x9 translates to a 2.9 mm nominal diameter and 9 mm length, suitable for medium-thickness metal work without protruding hardware.
• 
  Used condition—may show light cosmetic wear or patina; intact threads and seating surfaces ensure reliable performance for non-critical projects or spare-part kits.

Ideal use cases:

• Assembling or repairing metal enclosures, electrical cabinets, and small appliance housings where a flush, secure finish matters.
• Attaching lightweight brackets, panels, or internal components in hobby projects, DIY machines, or frames made from sheet metal.
• Maintaining inventory for classrooms, workshops, or repair shops where having a ready supply of self-tapping screws helps speed up builds.

Installation guidance to maximize results:

• Use a pilot hole or pre-threading when working with harder metals to ensure clean threading and prevent head stripping.
• Drive with steady, even pressure and avoid overtightening to protect both the screw and the workpiece.
• Pair with the appropriate driver bit to minimize head wear and maintain a firm seat in the screw head.

With its robust carbon steel makeup, practical dimensions, and reliable self-tapping action, this ST2.9x9 tapping screw is a versatile choice for everyday metal-fastening tasks. The used condition offers a cost-effective option for projects where appearance is less critical than function, making it a smart addition to any hardware lineup.
