Gibraltar ST3-25-G Equal Double Threaded Stud 5/8-11

Product Description

The GIBRALTAR ST3-25-G is an equal double threaded stud with a 5/8-11 thread size and an overall length of 2.5 inches. This stud features left and right thread direction on both ends, making it suitable for tension rod assemblies, mechanical linkages, and structural fastening applications. Manufactured from grade 1117 carbon steel with a black oxide finish, it provides corrosion resistance in moderate-exposure environments. At 0.17 pounds, it is a compact fastener used by machinists, millwrights, plumbers, and mechanical contractors in equipment assembly and maintenance work.

Equal double threaded studs like the ST3-25-G are commonly used in industrial and mechanical applications where a fixed threaded connection point is needed on both ends of a fastener. Typical uses include pump assemblies, pipe flanges, equipment mounting, and general mechanical fabrication. The black oxide finish helps reduce surface rust during storage and light service. This stud suits both commercial and light industrial settings where a standard 5/8-11 thread engagement is required.

Key Features

• Equal thread length on both ends with left and right thread direction for symmetric engagement
• 5/8-11 UNC thread size for compatibility with standard 5/8-inch fastener hardware
• 2.5-inch overall length suits compact fastening assemblies
• Grade 1117 carbon steel construction provides reliable tensile strength for general mechanical use
• Black oxide finish reduces surface oxidation and provides a uniform appearance

Compatibility

Designed as a standard 5/8-11 UNC equal double threaded stud for use in mechanical assemblies, equipment mounting, and general industrial fastening applications requiring symmetric threaded engagement on both ends.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical contractors using standard hand tools and thread gauges. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or anti-seize compound as required by the application or applicable maintenance standards. Power down or de-energize any associated equipment before servicing fasteners in live mechanical assemblies.
