Te-co 40504 Equal Double Threaded Stud 3/8-16 3 Inch

Product Description

The TE-CO 40504 is an equal double threaded stud designed for secure, load-bearing fastening applications in industrial and mechanical assemblies. Machined from medium-carbon steel with a black oxide finish, this driver stud provides corrosion resistance and consistent thread engagement on both ends. The stud measures 3 inches overall length with a 3/8-16 thread size, 1-inch threaded length on each end, and a 1-inch unthreaded shank in the center. It includes a flat for wrench or driver engagement during installation. Licensed tradespeople and industrial maintenance technicians specify this stud where equal thread engagement at both ends is required.

This stud fits standard industrial fixture and mechanical assembly applications where a threaded fastener must engage two separate components or surfaces simultaneously. The 3/8-16 thread pattern is a common coarse-thread specification found across a wide range of machinery, jigs, fixtures, and structural assemblies. The equal thread configuration ensures balanced load distribution, making it suited for clamping, positioning, and mounting setups in fabrication shops, machine shops, and maintenance environments.

Key Features

• Equal thread length on both ends for balanced engagement and load distribution
• 3/8-16 coarse thread size, compatible with standard nuts and threaded components
• 1-inch threaded length on each end with a 1-inch unthreaded shank center section
• Medium-carbon steel construction, Material Grade 5, for reliable tensile strength
• Black oxide finish for moderate corrosion resistance in dry and indoor environments
• Flat section on shank allows wrench or driver installation without thread damage

Compatibility

Designed as a standard replacement or new-installation driver stud for industrial fixtures, jigs, and mechanical assemblies using 3/8-16 coarse thread fasteners.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a wrench applied to the center flat. Always verify thread engagement depth and torque to the assembly specification before applying load. Inspect mating threaded holes for damage or contamination before installation. Do not over-torque, as medium-carbon steel studs are subject to yield at excessive applied force.
