Te-co 40806 Equal Double Threaded Stud 5/8-11 4 Inch Oal

Product Description

The TE-CO 40806 is an equal double threaded stud designed for secure fastening applications where both ends require threaded engagement. Manufactured from medium-carbon steel with a black oxide finish, this stud measures 4 inches overall length with a 5/8-11 thread size on both ends. Each end features a 1.5-inch thread length, a 1-inch unthreaded shank, and a flat for driver installation. The black oxide finish provides moderate corrosion resistance for shop and industrial environments. Machinists, tool and die technicians, and maintenance professionals install these studs in fixturing, workholding, and general mechanical assemblies.

The 40806 is suited for medium-duty industrial and manufacturing applications requiring a consistent, equal-length threaded stud. It is commonly used in fixture plates, jig components, and machine tooling setups where both ends must thread into mating parts or accept nuts. The grade 5 material rating makes it appropriate for applications with moderate tensile load requirements. This stud is sold individually per package with a minimum order of 2 units.

Key Features

• Equal double threaded ends - both ends share the same 5/8-11 thread specification
• 1.5-inch thread length on each end for secure engagement depth
• 1-inch unthreaded shank provides a positive shoulder reference between threaded zones
• Flat machined into shank for driver installation without marring threads
• Black oxide finish on medium-carbon steel offers moderate corrosion and wear resistance
• Material grade 5 construction for moderate tensile load applications

Compatibility

Designed as a standard equal double threaded stud for industrial fixturing, workholding, and mechanical assembly applications requiring a 5/8-11 threaded fastener with 4 inches overall length.

Installation Notes

Installation is performed by machinists or mechanical technicians using a standard hex driver or wrench on the machined flat. Ensure mating threaded holes or nuts are clean and free of debris before engagement. Do not exceed the torque capacity appropriate for grade 5 medium-carbon steel fasteners per applicable engineering standards. Inspect threads for damage before installation to prevent cross-threading or fastener failure.
