Increasing the diameter of the main bolt holes allows for stronger oversized main bolts or through-studs to be fitted, increasing the clamping force. This improves structural rigid ity and improves sealing under high loads. This service includes drilling and tapping the larger diameter holes for studs/bolts but does not include the studs/bolts themselves. Link to Through-Studs Link to Oversized Main Bolts Show more
