Product Features
Feature 1 :Adjustment Screws can be used to adjust the the workpiece position slightly through the adjusting screw, so as to play the role of precise positioning.
Feature 2 :The overall heat treatment (HRC35~42) has reduced abrasion caused by contact with workpiece.
Feature 3 :Unlike a flat end bolt, the front end round head makes point contact with the workpiece, thus absorbing the inclination of the tapped hole.
Feature 4 :Adjustment Screws coarse or fine thread pitch is available. Choose the fine thread type when slight adjustment is required.
Feature 5 :A nut for fixing the Adjustment Screws is included. Therefore, it can be fixed after purchasing the adjusting screw components.
Usage Method
Product DrawingsDetailed Description about Adjustment Screws usage
misumi MISUMI Adjusting screw Adjusting bolt M3 to M20 Complete method of use
Due to the Adjustment Screws use of a front end round head shape, it can absorb the eccentricity caused by the inclination of thread processing. Therefore, only one point can be used as a support for positioning.
