Pan head (round head), built-in Torx slot with plum blossom star, anti-theft and anti-slip, uniform disassembly and assembly force, not easy to grind the slot.
Half-tooth design, the upper section is smooth and smooth, the lower section is threaded, and the contact surface of the workpiece will not be scratched during assembly, and the movable gap can be reserved.
Flat tail, flat head, end face, no pointed tail, will not stab plate, plastic, aluminum alloy workpieces.
The overall blackening treatment, jet black and rust-proof, and the texture is firm.
High strength, high hardness, strong torque, lower cost, suitable for ordinary equipment, furniture, hardware fixation.
Anti-rust and corrosion-resistant, special for humid, outdoor, and bathroom environments, and not easy to rust and get stuck.
Plum blossom hexagon socket groove: Compared with cross/slotted screws, the torque is greater, it is not easy to slip teeth, and it has anti-theft effect.
Half-tooth light rod structure: After locking, the workpiece fits flatly to avoid deformation of the plate caused by the pull of the whole tooth.
Flat tail design: Suitable for thin plates, plastic parts, precision electronic parts, will not penetrate or scratch the substrate.
Surface blackening process: Improve wear resistance and anti-rust ability, and have a uniform and beautiful appearance.
Factory customization: Length, tooth length, head thickness, material, and surface treatment can be customized, and straight hair can be made in stock in bulk.

Aluminum alloy profile, plastic shell, precision equipment fixed
Industrial equipment, DIY modification, maintenance and installation, professional factories and manual assembly are common
What standard dimensions are available for these screws?
These screws follow metric standards with regular stock specifications covering M2 to M10. Custom overall lengths, thread lengths, and unthreaded rod sections can also be produced.
What is the advantage of a half-tooth (partially threaded) shaft?
The half-tooth structure features a smooth upper section that protects workpiece contact surfaces from scratches and maintains a flat fit without pulling or deforming thin plates.
Why use a plum blossom (Torx) socket instead of standard drives?
Torx drives provide significantly higher torque capability, reduce cam-out or tooth slippage during high-speed installation, and provide anti-theft and tamper-resistant benefits.
Which material should I choose: Carbon Steel or Stainless Steel?
Choose black carbon steel for cost-effective, high-strength, and high-torque mechanical connections. Choose stainless steel for humid, outdoor, or wet areas requiring superior corrosion resistance.
Why is the flat tail design important for electronics and plastics?
The flat, blunt end ensures that the screw will not puncture, scratch, or crack delicate internal components, circuit boards, aluminum sheets, or plastic casings during assembly.
