Gibraltar 74363243 Double Threaded Stud 5/16-18 1-1/2 in

Product Description

The GIBRALTAR 74363243 is an equal double threaded stud with a 5/16-18 unified coarse thread and an overall length of 1.5 inches. Manufactured from alloy steel with a black oxide finish, this stud is rated Thread Fit Class 2A, indicating a standard external thread tolerance suitable for general-purpose fastening applications. The black oxide finish provides mild corrosion resistance and reduces surface glare. This type of fastener is used by millwrights, pipefitters, HVAC technicians, electricians, and general mechanical tradespeople wherever a threaded connection is needed on both ends of a single fastener body.

Equal double threaded studs are commonly used in mechanical assemblies, equipment mounting, flanged connections, and panel fabrication. The equal stud design means both threaded ends are the same length, making them interchangeable and suited for symmetrical clamping or through-bolt applications. This stud is appropriate for use in light-duty to medium-duty industrial and trade service environments where alloy steel strength is required and a factory-applied protective finish is preferred.

Key Features

• 5/16-18 unified coarse thread on both ends for standard nut compatibility
• Alloy steel construction provides greater tensile strength than low-carbon alternatives
• Black oxide finish offers mild corrosion resistance and a clean appearance
• Thread Fit Class 2A ensures consistent fit with standard Class 2B threaded nuts and inserts
• Equal thread length on both ends supports symmetrical assembly configurations
• Compact 1.5-inch overall length suits tight-clearance installations

Compatibility

Designed as a general-purpose equal double threaded stud compatible with standard 5/16-18 threaded nuts, couplings, and inserts conforming to unified inch screw thread standards.

Installation Notes

Installation is performed by threading one end into a tapped hole or coupling, then securing the assembly with a nut on the exposed end. Power down or de-energize any equipment before fastener installation in electrical or HVAC panels. Use calibrated torque tools appropriate to the fastener size and joint material to avoid thread stripping in softer base materials. Follow applicable mechanical codes for the specific trade application.
