8T0273 Hex Socket Head Bolts for Caterpillar Equipment

8T0273 is a hex socket head bolt used with equipment manufactured by Caterpillar. The bolt has an internal hex drive, a smooth flange face and a coarse standard thread. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The available product data identifies the compatible equipment brand as Caterpillar but does not specify individual machine models or series. Model-level fitment should therefore be confirmed against the part number and the dimensions required for the particular assembly before installation.
