Te-co 40712 Equal Double Threaded Stud 1/2-13 7 Inch

Product Description

The TE-CO 40712 is an equal double threaded stud designed for secure fastening in industrial and mechanical assembly applications. Manufactured from medium-carbon steel with a black oxide finish, this driver stud provides corrosion resistance and a consistent surface hardness suited for high-load clamping setups. The stud measures 7 inches overall length with a 1/2-13 thread size on both ends and a 4-inch unthreaded shank in the center. Each end carries a 1-1/2-inch threaded length, and the stud includes a flat for driver engagement. Grade 5 material classification ensures reliable tensile strength for demanding fixture and tooling applications.

This double threaded stud is used in workholding, fixture building, jig construction, and general industrial fastening where equal engagement on both ends is required. The equal thread configuration makes it well suited for through-hole assemblies and stud-mount clamping systems on machine tables and tooling plates. It is installed by machinists, tool and die technicians, and maintenance mechanics across manufacturing environments. The black oxide finish provides mild corrosion protection in shop conditions.

Key Features

• Equal double threaded ends for symmetrical engagement on both sides of an assembly
• 1/2-13 thread size on both ends with 1-1/2 inch thread length per end
• 4-inch unthreaded shank for clearance through workpiece or fixture body
• Medium-carbon steel construction at material Grade 5 for reliable tensile strength
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Flat included on shank for driver engagement during installation

Compatibility

Designed as a standard driver stud for use in industrial workholding and clamping systems requiring a 1/2-13 equal double threaded configuration with a 7-inch overall length.

Installation Notes

Installation is typically performed by machinists or maintenance mechanics using a hex wrench or flat-driver tool engaged at the shank flat. Ensure the receiving threaded hole or nut is clean and free of debris before threading in. De-energize or lock out any powered equipment before working in the fixture area per applicable safety procedures. Do not exceed the torque rating of the mating threaded component or fixture material.
