Specifications: <br> <br> Thickness that can be used for work: 2 inches <br> <br> Drill-hole Sizes: 1/4", 5/16", 3/8", 7/16" and 1/2" <br> <br> Six hardened steel bushings: Two of each 1/4-Inch, 5/16-Inch and 3/8-Inch sizes <br> <br> <br> <br> Product design: <br> <br> Just very little operation to meet more professional needs, very suitable for creating different pin joints<br> <br> Quality Material: Aluminum alloy material, stable with high corrosion resistance <br> <br> <br> <br> How to solve the problem of not centering？<br> <br> ① If the left and right distances of individual products are asymmetric and there is deviation during use, it can be adjusted.<br> <br> ② Unscrew the two left screws with the hexagon socket. <br> <br> ③ Adjust the large screw on the middle rod to make the left and right distance of the product consistent. <br> <br> ④ After the left and right distances are the same, tighten the left two socket head cap screws.<br> <br> ⑤ Rotate the small rotating rod, and check whether the left and right distances are uniform in the experiment. <br> <br> If they are consistent, they can be used after debugging. If there is any slight deviation, adjust them slightly according to the above steps. <br> <br> ⑥After debugging, the left and right distances are the same. <br> <br> ⑦ In order to ensure the quality of the products, we will give you a small wrench, which can be adjusted if there is any deviation during use. <br> <br>
