Serrated flange bolts like this 5/16-18 UNC with a length under head of 2-3/4 inches and fully threaded construction are invaluable components designed to securely fasten materials in various industries where superior grip is necessary. Often found in plumbing, piping or HVAC systems where tightening under tension is essential, these bolts feature teeth on the underside of the head providing exceptional traction for securing parts into position while preventing unscrewing when torqued down. Their length under head ensures a flush fit after tightening and meets ASME/ANSI standards for B1.20 series A fasteners, making them ideal choices for machinery manufacturing or structural fabrication projects where durability is key.
