These multi-purpose, semi-permanent interior track fittings are specifically designed to be threaded into the part to be mounted. Our Threaded Stud is designed as an interior tie down incorporating a steel stud and retainer for use where multiple attachments are required. Incredibly easy to insert, they come equipped with a knurled nut or two knurled nuts for easy tightening by hand or with two hex nuts for easy tightening with a tool. Threaded Studs without nuts are also available. Other sizes and variations may be available on special request and may be subject to minimum quantities.
