Gibraltar 40903G Double Threaded Stud 3/4-10 4 in Alloy Steel

Product Description

The GIBRALTAR 40903G is an equal double threaded stud designed for bolted assemblies that require threaded engagement on both ends without a fixed head. Machined from alloy steel with a black oxide finish, this stud carries a material grade of 5 and a thread fit class of 50, making it suitable for moderate-to-high strength fastening applications. The 3/4-10 unified coarse thread runs equally on both ends, and the stud measures 4 inches in overall length. A flat is included on the shank for wrench engagement during installation and removal. Mechanical contractors, millwrights, pipefitters, and maintenance technicians commonly use equal double threaded studs when assembling flanged connections, equipment mounting frames, and structural brackets.

This stud is appropriate for general industrial and mechanical installations where a fully threaded, headless fastener is required. Equal double threaded studs are commonly specified in equipment bases, pump mounts, compressor frames, and similar fixed-assembly applications across commercial and industrial facilities. The black oxide finish provides mild corrosion resistance in dry or lightly oiled environments. Sold individually.

Key Features

• Equal thread engagement on both ends — same thread length on each side for symmetrical load distribution
• 3/4-10 unified coarse (UNC) thread for broad nut and coupling compatibility
• 4-inch overall length suits standard equipment mounting and flange applications
• Alloy steel construction with material grade 5 for enhanced tensile strength over mild steel
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Flat on shank allows positive wrench grip during installation

Compatibility

Designed as an OEM-style replacement or standard component for mechanical assemblies requiring a 3/4-10 UNC equal double threaded stud at 4 inches overall length.

Installation Notes

Installation is typically performed by mechanical or maintenance technicians using an appropriate stud driver or double-nut method for torquing. Always de-energize and lock out equipment before working on fastened assemblies. Thread engagement depth on both ends should meet standard fastener engineering minimums — consult applicable mechanical codes or engineering specifications for the assembly. Do not exceed the rated material grade load limits for this stud class.
