Gibraltar 40350G Unequal Double Threaded Stud 1/4-20

Product Description

The GIBRALTAR 40350G is an unequal double threaded stud with a 1/4-20 thread size and a 1.5-inch overall length. This stud features two different thread lengths on a single shank: a long thread of 0.88 inches and a short thread of 0.38 inches. Made from grade 5 carbon steel with a black oxide finish, it is suited for mechanical and industrial fastening applications where a threaded post is required on both ends of a connection. Licensed trades and industrial maintenance personnel commonly install these as part of bolted assemblies, brackets, and mounting hardware.

The 40350G is used in light to medium mechanical assemblies where a fixed threaded anchor point is required. The unequal thread lengths allow flexibility in how deep each end engages its mating component, making it appropriate for applications such as equipment mounting, panel fastening, and structural bracketing. It is commonly found in HVAC equipment assemblies, electrical enclosures, and general mechanical systems.

Key Features

• Unequal thread configuration: 0.88-inch long thread and 0.38-inch short thread on a single 1.5-inch stud
• 1/4-20 thread size for wide compatibility with standard fastener hardware
• Grade 5 carbon steel construction for adequate tensile and shear strength in light to medium duty use
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Thread fit class 50 for controlled tolerance engagement
• No flat, continuous round shank profile for clean through-hole installation

Compatibility

Designed as a standard 1/4-20 double threaded stud for use in mechanical assemblies, equipment mounting, and fastening applications requiring threaded engagement on both ends.

Installation Notes

Installation is typically performed by mechanical, HVAC, or electrical technicians using standard hand tools. Ensure both mating threaded holes or nuts are clean and free of debris before threading the stud. Apply appropriate thread engagement depth on each end before applying load. Do not exceed rated material grade load limits for the assembly.
