Te-co 40808 Equal Double Threaded Stud 5/8-11 5 in Oal

Product Description

The TE-CO 40808 is an equal double threaded stud designed for secure fastening applications in industrial and mechanical assemblies. Machined from medium-carbon steel with a black oxide finish, this driver stud features a 5/8-11 thread size and a 5-inch overall length. Both threaded ends measure 1-3/4 inches in length, with a 1-1/2-inch unthreaded shank centered between them. The black oxide finish provides moderate corrosion resistance and reduces light reflection on the fastener surface. Machinists, millwrights, and maintenance technicians working with fixtures, jigs, or machine components will find this stud suitable for standard threaded insert and stud-drive applications.

This stud is intended for use in industrial fixture building, machine assembly, and tooling setups where a centered equal-thread configuration is required. The 5/8-11 coarse thread is a widely used standard in medium-duty steel fabrication and fixture work. The flat feature on the shank allows positive engagement with a wrench or driver tool during installation, reducing the chance of the stud spinning freely in the bore. It is sold individually and is appropriate for trade and shop use wherever a Grade 5 medium-carbon steel double-end stud is specified.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using hand tools or a stud driver. Ensure the receiving tapped hole is clean and free of debris before threading the stud in. Power down or de-energize any associated equipment before servicing fasteners in live assemblies. Use the flat on the shank to drive the stud without damaging the threads.
