Gibraltar ST1-30-G Equal Double Threaded Stud 3/8-16 3in

Product Description

The GIBRALTAR ST1-30-G is an equal double threaded stud designed for mechanical fastening applications requiring threaded engagement on both ends. Machined from 1117 carbon steel with a black oxide finish, this stud measures 3 inches in overall length and carries a 3/8-16 unified coarse thread on both ends with left and right thread direction. The black oxide finish provides mild corrosion resistance and reduces light reflection in finished assemblies. Weighing approximately 0.07 pounds, it is a compact, precision fastener suited for use by millwrights, maintenance technicians, and mechanical contractors working on equipment assemblies, machinery mounts, and structural connections.

Equal double threaded studs like the ST1-30-G are commonly used in industrial and mechanical maintenance settings where a bolt cannot be rotated during installation. Typical applications include equipment flanges, threaded rod connections, motor mounts, and general assembly work requiring stud fastening into a tapped hole on one end with a nut secured on the opposite end. The equal thread length on both ends makes this stud interchangeable in either orientation, simplifying installation in tight or blind-access situations.

Key Features

• Equal double threaded configuration allows identical thread engagement on both ends
• 3/8-16 unified coarse thread provides strong holding power and broad nut compatibility
• 1117 carbon steel construction offers good machinability and tensile strength
• Black oxide finish adds mild corrosion resistance and reduces surface reflectivity
• 3 inch overall length suits a wide range of standard mechanical assembly applications
• Left and right thread direction on each end for versatile installation orientation

Compatibility

Designed as a standard equal double threaded stud for use in any mechanical assembly or equipment application requiring a 3/8-16 threaded fastener with 3 inches of overall length.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or mechanical contractors using a stud driver or double-nut method to torque into a tapped hole. De-energize and lock out equipment before installing or removing studs in powered machinery. Apply thread-locking compound or anti-seize as required by the assembly specification. Inspect tapped holes for damage or contamination before installation to ensure full thread engagement.
