Te-co 40706 Equal Double Threaded Stud 1/2-13 4 in Oal

Product Description

The TE-CO 40706 is an equal double threaded stud with a 1/2-13 thread size and a 4-inch overall length, finished in black oxide over medium-carbon steel. This driver stud features equal thread lengths on both ends - each measuring 1.5 inches - with a 1-inch unthreaded shank in the center. The black oxide finish provides a baseline level of corrosion resistance and reduces light reflection on the fastener body. A flat is included on the shank for wrench engagement during installation. This stud is a common fastener used in fixturing, clamping, and general industrial assembly applications where a stud-and-nut connection is required on both ends.

The 40706 is suited for medium-duty industrial and trade applications requiring a through-stud connection. It fits where standard 1/2-13 UNC thread engagement is specified. Typical use cases include workholding fixtures, jig assemblies, and mechanical clamping setups. The material grade 5 rating indicates the stud meets medium-strength requirements appropriate for general mechanical fastening rather than high-load structural applications. Licensed trades and industrial maintenance technicians commonly source this stud for fabrication and equipment assembly work.

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for applications requiring 1/2-13 UNC double-threaded studs with a 4-inch overall length in medium-carbon steel construction.

Installation Notes

Installation should be performed by a qualified mechanic or industrial technician familiar with standard fastening practices. Use the wrench flat on the unthreaded shank to drive the stud into the receiving thread without damaging either thread end. Ensure the mating threaded holes or nuts are clean and free of debris before installation. Apply thread-locking compound or anti-seize as appropriate for the service environment and expected load.
