Te-co 40709 Equal Double Threaded Stud 1/2-13 5.5 in Oal

Product Description

The TE-CO 40709 is an equal double threaded stud designed for secure mechanical fastening in fixture, tooling, and workholding applications. Manufactured from medium-carbon steel with a black oxide finish, this stud features matching 1/2-13 threads on both ends with an unthreaded shank in the center. The overall length is 5.5 inches, with each threaded end measuring 1.5 inches and the unthreaded shank measuring 2.5 inches. The flat drive feature allows installation with a wrench, making it practical for tight or recessed mounting situations. It falls within the driver studs category and carries a material grade of 5.

This stud is suited for use in manufacturing, machine shop, and industrial maintenance environments where repeatable, rigid connections are required. Typical applications include jig and fixture assembly, clamping systems, and modular workholding setups. The equal thread configuration means either end can serve as the drive end or the mating end, providing installation flexibility. Both trade professionals and maintenance technicians working with precision tooling and fixturing hardware will find this part a direct fit for standard 1/2-13 threaded assemblies.

Key Features

• Equal 1/2-13 threads on both ends for consistent engagement at either side
• Overall length of 5.5 inches with a 2.5-inch unthreaded shank
• Thread length of 1.5 inches per end for reliable thread engagement depth
• Medium-carbon steel construction, material grade 5, for strength in high-load applications
• Black oxide finish provides mild corrosion resistance and reduces light reflection in precision environments
• Flat drive feature enables wrench installation without slippage

Compatibility

Designed as an OEM-style replacement or standard component for industrial fixtures, jigs, and workholding systems requiring 1/2-13 threaded studs with a 5.5-inch overall length.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using an open-end or combination wrench on the flat drive section. Ensure mating threaded holes are clean, free of debris, and within tolerance before installation. Do not overtighten, as this can strip threads or induce stress fractures in the shank. Torque to the fastener specifications defined by your fixture or equipment design documentation.
