The dimensions you have chosen are: the inner diameter D of the shaft hole of the bracket is 12 mm; the inner diameter K of the other shaft hole is 12 mm. Different capital letters are used in the product drawings to represent the dimensions of the various detail positions on the product. The specific dimensional data can be found under the corresponding letters in the specification sheet, and several sizes are available. BulletPoint2 : [Material of main body: Aluminium Alloy]; [Finish of main body: Black Anodize]; [Material of fastening bolts: Carbon Steel]; [Finish of bolts: Black Oxide]. BulletPoint3 : This bracket supports and secures shafts or pipes, etc., and can also withstand certain loads. The shaft hole of the bracket can be adjusted for locking effect by turning the bolt. When locking shafts or pipes with uneven surfaces, the clearance between the shaft and the bracket can be controlled by twisting the bolt, making it easy to lock the shaft or dismantle it on the spot during use, so that it can be applied to a wider range of use scenarios and enhance use efficiency. BulletPoint4 : This bracket accessory includes two locking bolts that lock the bracket's shaft holes. The bolts are hexagon socket head cap screws that can be turned with a hexagonal spanner to control the locking of the shaft holes. This bracket is usually used for connecting 2 straight cross-crossing pillars, and can flexibly assist the positioning and installation of pillars by adjusting the height, width and angle. BulletPoint5 : Warm reminder: the data on this page are in metric millimetres. As the sizes are measured manually, there may be a slight error, but the error will be less than ±0.5 mm, please understand.
