M3 x 5mm Cup Point Grub Screws

High Tensile Grade 45H Steel | Hex Socket Drive | Pack of 10

These M3 x 5mm Grub Screws (also known as Socket Set Screws) are engineered for high-stress applications where a secure, permanent-style grip is required. Manufactured from Grade 45H High Tensile Steel, these fasteners offer significantly higher hardness and torque resistance than standard stainless steel or lower-grade carbon screws.

The Cup Point design features a thin edge that digs into the mating surface (such as a motor shaft or axle), providing superior resistance to rotation and vibration.

 

Key Performance Features

  • Grade 45H Strength: Hardened steel construction designed to withstand high tightening torques without stripping the hex socket.

  • Precision Cup Point: Specifically designed to InchbiteInch into shafts for maximum holding power and security.

  • Metric Coarse Thread: M3 x 0.5mm standard pitch for universal compatibility in electronics, robotics, and machinery.

     

  • Corrosion Protection: Finished with a protective black oxide coating for industrial-grade durability.
