Description/Basics
Adjusting screws for mechanical engineering are intended primarily for positioning the most diverse components. In this case, the adjustment screw sets a predetermined distance of the respective component.
Depending on the application, the MISUMI range offers adjusting screws with control threads and adjusting screws with fine threads. A fine-threading facilitates positioning, since a smaller torque is required for the adjustment. Due to the lower slope of the fine thread, a fine threaded adjusting screw is loosened with less probability than one with standard threads. Another advantage of fine threading is the higher load capacity, which allows higher loads to be accommodated in axial direction. In addition, a locating bolt with a fine thread can generate a higher actuating force due to the low pitch.
The loosening or unintentional adjustment of an adjusting screw can be prevented with a locknut. Depending on the design, the appropriate nut is supplied as an accessory for the adjusting screw. Please see the specifications for more information.
An adjusting screw with knurled head facilitates easy manual adjustment without additional tools. The adjusting screw with knurled head is often used where regular adjustment or component replacement is necessary.
The locating bolt is available with a hardened contact surface. It may be hardened on the thread face or on the head or drive. Tempering ensures greater wear protection of the adjusting screw and increases the service life compared to conventional adjusting screws. The additional compensation process can cause discoloration of the material near the contact surface.
Adjusting screws are also available in the form of hexagon sockets. Without a head as drive, which can be advantageous, especially in inaccessible places.
Adjusting screws are often used in combination with stop pins or height adjusting pins. These bolts are inserted into the component to be moved in order to protect it from wear and tear or damage due to multiple adjustments.
Adjusting screws are often found in workpiece carriers and clamping devices. MISUMI also offers similar adjusting screws or locking bolts with a brush head in the form of stopper bolts.
MISUMI offers suitable threaded stopper blocks, optionally with standard threads and fine threads.
