When installing post clamp and tightening the screw, if slippage occurs and tightening is impossible, what should be done?

It is suggested to check whether there is wear around the screw and the threaded hole respectively before tightening the screw; avoid excessive force or deviation during tightening, which may easily lead to slippage.

Are there bolts supplied for this model of MISUMI post clamp? How many?

This model of post clamp is equipped with supplied bolts. However, the number of supplied bolts will vary with the shaft diameter. For details, please refer to the supplied bolts section published in our catalog.

Is there a guaranteed range for the verticality of this post clamp?

According to our catalog, verticality is the guarantee value before the opening of the post clamp. Due to the release of internal force after opening machining, this guarantee value will deviate and this specification range is no longer guaranteed.

Are there any other types of post clamps available in addition to square shape post clamps?

According to the fixing position (vertical, parallel) of the post and the diameter (Equal Dia., Unequal Dia.), there are different types and shapes to choose from. For details, please search 'post clamps' in the official website of MISUMI.

Product Overview of Double Post Type

It is a workpiece used for connecting two posts with the same diameter, which can be fixed at a certain position by adjusting the height, width, and angle. Same diameter perpendicular post is the most commonly used Double Post Type

Product Feature of Double Post Type

Feature 1: same diameter perpendicular post is the most commonly used Double Post Type.
Feature 2: over-cutting process is added, and bolts are locked for fixing, so that the clamping force is stable and lasting.
Feature 3: new economy series Double Post Type clamps can be used under two different conditions, i.e. same diameter and different diameter, and the design freedom is high.
Feature 4: available with two kinds of surface treatment: white anodizing and black anodizing. Black anodized products can prevent reflection and have a wider range of applications.
Feature 5: new economy series Double Post Type clamps are sold in the form of full-model inventory, so as to realize practical short delivery time and shipment in 1 day.

Dimensional Drawing of Double Post Type

For dimensions not indicated, the tolerance of Φ20 and below is ±0.3.Φ The tolerance of 25 and above is ±0.5.
After the Double Post Type

mounting hole D is machined according to the tolerance of 0 to +0.05, the opening is machined. The tolerance of the hole after machining will be changed.
