Product Description
Product Description
Product Description:Cross Grub Screw or Cross Set Screw is a headless set screw with a cross groove on the head, mainly used to fix parts axially and prevent relative movement
Selection precautions
Size matching
The diameter and pitch of the screw must be perfectly matched with the blade and body, otherwise it may cause thread damage or loose fixation.
Torque requirements
Tighten according to the manufacturer's recommended torque value (refer to the tool manual). Over tightening may break the screw, while over loosening may cause the blade to shift.
Maintenance and replacement
Regularly check whether the screws are loose or worn, and it is recommended to use original accessories for replacement to ensure compatibility.
