The GIBRALTAR 40308G is an equal double threaded stud with a 1/4-20 thread size and an overall length of 5 inches. Double threaded studs feature male threads on both ends with no head, allowing them to be threaded into a tapped hole on one end and secured with a nut on the other. This stud is manufactured from alloy steel with a black oxide finish and carries a material grade of 5, making it suitable for moderate-to-high-strength fastening applications. It is a common hardware component used by trades professionals, maintenance technicians, and assembly personnel across industrial and mechanical applications.
This stud is appropriate for use in general mechanical assemblies, HVAC equipment mounting, plumbing fixture anchoring, and electrical enclosure hardware where a through-bolt is not practical. The equal thread configuration means both threaded sections are the same length and thread spec, making it straightforward to orient during installation. Its black oxide finish provides mild corrosion resistance in dry or mildly humid environments.
Designed as a standard 1/4-20 equal double threaded stud for use in any assembly requiring a headless fastener with matching threads on both ends. Verify tapped hole depth and thread engagement requirements before installation.
Installation is typically performed using a stud setter, two jam nuts, or locking pliers to drive the stud into a pre-tapped hole. Ensure the receiving material is tapped to the correct 1/4-20 thread specification before installation. De-energize or shut off any equipment before installing fasteners in live assemblies. Do not exceed the rated clamp load for grade 5 alloy steel fasteners in the application.
