Gibraltar 40506G Equal Double Threaded Stud 3/8-16 4 in

Product Description

The GIBRALTAR 40506G is an equal double threaded stud with a 3/8-16 thread size and an overall length of 4 inches. It is manufactured from alloy steel with a black oxide finish and carries a Grade 5 material rating and a Thread Fit Class 50 designation. This stud features a flat, making it suitable for secure fastening in structural, mechanical, and equipment assembly applications. It is installed by machinists, millwrights, maintenance technicians, and trade professionals who require a reliable, corrosion-resistant fastener in demanding service environments.

This double threaded stud is intended for use in bolted connections where a stud must thread into a tapped hole on one end and accept a nut on the other. The equal-length thread configuration on both ends makes it well suited for through-bolt and fixed-stud fastening in HVAC equipment frames, mechanical assemblies, pump and motor mounting, and general industrial fabrication. Its black oxide finish provides mild corrosion resistance suitable for indoor or protected environments.

Key Features

• Equal double threaded configuration on both ends for versatile fastening applications
• 3/8-16 thread size with Thread Fit Class 50 for consistent engagement tolerances
• Alloy steel construction with Grade 5 material rating for high load-bearing strength
• Black oxide finish provides mild corrosion and abrasion resistance
• Flat included for secure installation and controlled torque application
• 4-inch overall length suits a wide range of standard fastening depths

Compatibility

Designed as a standard replacement or new-installation fastener for 3/8-16 threaded applications in HVAC, mechanical, and industrial equipment assemblies requiring a Grade 5 alloy steel double threaded stud.

Installation Notes

Installation is typically performed by mechanical or maintenance technicians using standard hand tools and a stud driver or double-nut method. Always ensure the mating tapped hole is clean and undamaged before threading the stud. De-energize all electrical systems and relieve any pressure from the assembly before servicing fasteners in live equipment. Follow applicable torque guidance for 3/8-16 Grade 5 fasteners per the equipment manufacturer or applicable mechanical codes.
