Micro-insert (Insert nut สำหรับอุดหลังจากสวมอัดด้วยความร้อน)
Knurling in alternate directions provides high tensile and torque strengths.
The symmetric design without orientation increases productivity and is advantageous for automatic machinery.

Major Insertion Methods Heat Staking Insertion, Ultrasonic Insertion, High Frequency Insertion
Material Brass (C3604), Aluminum Alloy (made-to-order),
Stainless steel (made-to-order)
Plastic Thermoplastics


■ Features
  • Non-orientation design for higher productivity
  • Knurling in alternate directions provides high strength
  • Suitable for use in automatic feeders and parts feeders
  • Full compliance with RoHS Directive

■ 注記
  • The MS2.5-M1.6-3.0 has a different shape than the illustration above.
  • Headed inserts are also available.
  • Please contact us if you need Pb-free material for environmental reasons.
  • Pilot hole diameters are for reference only.
  • The diameter should be determined by tests before use.
  • Please contact us about the knurling design when knife locks are used for polycarbonate (PC) and other materials which are sensitive to residual stress.
  • The diameter of the pilot hole for the mounting object should be smaller than the outer diameter of the insert (Dimension C).
  • When inserts are tightened by screws, choose the screw length so that screws do not reach the bottom of insert pilot holes.
  • The specifications are subject to change without notice.
  • Please contact us if you have any other questions.
