Te-co 40705 Equal Double Threaded Stud 1/2-13 3.5 Inch Oal

Product Description

The TE-CO 40705 is an equal double threaded stud designed for secure clamping and fixturing applications in machine shops, tooling setups, and industrial assembly. Manufactured from medium-carbon steel with a black oxide finish, it provides corrosion resistance and a consistent mating surface. The stud features a 1/2-13 thread size on both ends, an overall length of 3.5 inches, and a 1-inch unthreaded shank in the center. A flat is included on the shank for wrench engagement during installation and removal. Grade 5 material ensures reliable tensile strength for demanding workholding applications.

This stud is suited for use in T-slot tables, fixture plates, and clamping setups commonly found in machining, fabrication, and tooling environments. The equal thread configuration on both ends allows consistent engagement depth on each side, making it practical for through-bolt and stud-mount clamping arrangements. Machinists and tooling technicians typically use these in conjunction with T-nuts, clamps, and step blocks on milling machines and drill presses.

Key Features

• Equal double threaded ends with 1/2-13 thread size for consistent dual-side engagement
• Overall length of 3.5 inches with a 1-inch unthreaded shank
• Thread length of 1.25 inches per end for secure fastener seating
• Medium-carbon steel construction at Material Grade 5 for reliable load capacity
• Black oxide finish provides moderate corrosion resistance in shop environments
• Flat on shank allows wrench-assisted installation and removal

Compatibility

Designed as a standard driver stud for use in workholding and fixturing systems that accept 1/2-13 threaded components, including T-slot clamping sets and fixture assemblies.

Installation Notes

Installation is typically performed by machinists or tooling technicians using an open-end or combination wrench on the flat shank section. Ensure mating threads are clean and free of debris before assembly. Do not over-torque the stud into cast iron T-slots or soft fixture plates, as thread stripping may result. Always verify that the clamping setup is properly secured before operating machinery.
