Gibraltar 41118G Equal Double Threaded Stud 1-8 Thread 20 in

Product Description

The GIBRALTAR 41118G is an equal double threaded stud designed for heavy-duty fastening applications where both ends require threaded engagement. Machined from Grade 5 alloy steel with a black oxide finish, this stud measures 20 inches overall length with a 1-8 UNC thread size and a Thread Fit Class 50 designation. The equal double threaded configuration means both threaded ends are identical in length, making it suitable for through-bolt and tensioning assemblies. Weighing 3.76 pounds, this stud is built for applications requiring significant load capacity and corrosion-resistant surface treatment. Licensed tradespeople in mechanical, structural, and industrial maintenance work will commonly specify this fastener type.

This stud is used in industrial and commercial fastening assemblies where a continuous threaded rod or double-end stud is required. Typical applications include structural anchoring, equipment mounting, flange connections, and mechanical assemblies that demand a secure threaded interface on both ends. The flat feature allows for positive wrench engagement during installation. The black oxide finish provides mild corrosion resistance in interior and protected environments, making this stud appropriate for shop fabrication and field mechanical work.

Key Features

• Equal double threaded ends — both ends share the same 1-8 UNC thread specification
• Grade 5 alloy steel construction for high tensile strength in demanding fastening applications
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Thread Fit Class 50 ensures controlled thread engagement and consistent fit
• Flat feature allows secure wrench grip during torquing
• 20-inch overall length suits deep through-bolt and long-reach anchoring assemblies

Compatibility

Designed as an OEM-style replacement or direct-use fastener for industrial and commercial mechanical assemblies requiring a 1-8 UNC equal double threaded stud with a 20-inch overall length.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with fastener torque requirements and thread engagement standards. Verify that mating threads are clean and free of debris before assembly. Apply thread lubricant or anti-seize compound as specified by the equipment manufacturer or applicable fastening standard. Follow relevant industry codes and manufacturer guidelines for minimum thread engagement depth to ensure rated load performance.
