National standard pure brass countersunk head hexagon socket head screw flat head copper cup screw bolt copper machine tooth screw

Core advantage

• Countersunk structure, flush surface
  After tightening, the screw head is completely hidden in the counterbore, and the surface of the workpiece is flat, so that the hand can not be scraped, the wire can not be hooked, and the sliding piece can not be interfered, and the appearance is simple.
• Hexagon socket, anti-slip teeth, can bear large torque.
  Compared with the cross/straight groove, the hexagon socket is stressed evenly, and it is not easy to collapse and slip. It can be assembled by hexagon wrench and electric batch, which is convenient for disassembly and operation in narrow space.

• Unique characteristics of brass material

  -Excellent electrical and thermal conductivity, suitable for conductive grounding and heat dissipation assembly.

Application scenario

• Electronic and electrical (most commonly used)

  PCB board fixing, chassis shell, grounding terminal, power distribution cabinet, instrument shell, using the conductive and non-magnetic characteristics of brass, the shell is flat and without bumps to avoid scratching the line.

• Precision instruments and testing equipment

  Optical instruments, laboratory equipment, MRI supporting components and sensor housings are free of magnetism and do not interfere with the magnetic field, and the surface is smooth and safe.

• High-end decoration, musical instruments, handicrafts

  Wooden musical instruments, luxury hardware, retro decoration, golden appearance with fastening and decoration, smooth surface.
