Internally Threaded Rod: Aluminum, Plain, 12 in Lg, 1 in Thread Lg A, 1 in Thread Lg B, Right Hand

Internally threaded double-end rods and studs are hollow fasteners used to join two threaded male components, such as screw anchors. They can also be used as threaded inserts, or standoffs, for applications that require extended reach.

Double-end threaded rods and double-end threaded studs are fasteners that are threaded at each end with an unthreaded portion at the center. Also called connecting rods or double ended studs, they are typically used to join together female-threaded components that don't require a full thread or items that have different thread sizes. Double-end threaded rods are often bent to make specialized fasteners such as anchor bolts and U-bolts. These fasteners are commonly used in construction applications, plumbing fittings, metal fabrication, and machinery repairs.
