Gibraltar 40352G Unequal Double Threaded Stud 1/4-20 2.5in

Product Description

The GIBRALTAR 40352G is an unequal double threaded stud with a 1/4-20 thread size and an overall length of 2.5 inches. This fastener features two threaded ends of different lengths: a long thread of 1 inch and a short thread of 0.375 inches, with an unthreaded shank in between. Constructed from Grade 5 carbon steel with a black oxide finish, it is suited for applications requiring a corrosion-resistant, moderate-strength threaded connection. Machinists, maintenance technicians, and general fabricators install this type of stud where a fixed fastening point is needed on both ends of an assembly.

Unequal double threaded studs like the 40352G are commonly used in light industrial, mechanical, and structural assembly work. The unequal thread lengths allow one end to be permanently installed into a tapped hole or fitting while the longer or shorter opposing end accepts a nut, bracket, or mating component. This stud is appropriate for general-purpose fastening in machinery, equipment enclosures, and mounting applications where a Grade 5 carbon steel fastener meets the load requirement.

Key Features

• 1/4-20 unified coarse thread on both ends for broad hardware compatibility
• Unequal thread lengths: 1 inch long thread and 0.375 inches short thread
• Overall length of 2.5 inches for standard stud-mount applications
• Grade 5 carbon steel construction for moderate tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Thread Fit Class 50 for consistent dimensional tolerancing

Compatibility

Designed as an OEM-style replacement or general-purpose fastener for assemblies requiring a 1/4-20 unequal double threaded stud in 2.5-inch overall length with Grade 5 carbon steel construction.

Installation Notes

Install the short-thread end into the tapped receiving hole and the long-thread end to accept the mating nut or component, following the thread engagement depth required by the application. Ensure the tapped hole is clean and properly sized for 1/4-20 thread before installation. Use appropriate hand tools and follow applicable mechanical fastener standards for torque guidance based on Grade 5 material. Always confirm the black oxide finish is adequate for the corrosion exposure level of the installation environment.
