Gibraltar 40717G Equal Double Threaded Stud 1/2-13 12 in

Product Description

The GIBRALTAR 40717G is an equal double threaded stud with a 1/2-13 UNC thread form and a 12-inch overall length. Both ends carry the same thread size and pitch, making this a fully symmetric fastener suitable for applications where identical engagement on both ends is required. Constructed from alloy steel with a black oxide finish, this stud carries a Grade 5 material rating and a Class 50 thread fit for reliable clamping performance. The flat feature on the stud body provides a positive wrench surface for installation and removal. Licensed tradespeople in HVAC, plumbing, electrical, and general mechanical work use this type of fastener for equipment mounting, structural assembly, and fixture installation.

This stud is suited for residential and commercial mechanical applications where a through-bolt or anchor-style fastener is needed. Common uses include securing equipment bases, mounting structural brackets, and assembling flanged connections where nuts are applied to both ends. The 12-inch length accommodates thicker assemblies or applications requiring extended thread engagement on both sides of a clamped joint. Its alloy steel construction handles the mechanical stresses typical of HVAC equipment pads, pipe supports, and panel mounting applications.

Key Features

• Equal thread form on both ends: 1/2-13 UNC for consistent engagement at each end
• 12-inch overall length accommodates thick assemblies and extended reach applications
• Alloy steel construction with Grade 5 material rating for reliable mechanical strength
• Black oxide finish provides moderate corrosion resistance in indoor or sheltered environments
• Class 50 thread fit ensures consistent thread tolerance and reliable nut engagement
• Flat on stud body allows use of a wrench for controlled installation and removal

Compatibility

Designed as a standard 1/2-13 UNC equal double threaded stud for use in general mechanical, HVAC, plumbing, and electrical equipment assembly applications where a Grade 5 alloy steel fastener is specified.

Installation Notes

Installation is typically performed by licensed mechanical, HVAC, or electrical technicians using appropriate wrenches applied to the flat on the stud body. De-energize and lock out all equipment before installing or removing fasteners in electrical or mechanical assemblies. Apply fastener torque in accordance with the applicable equipment manufacturer specification and relevant code requirements. Inspect threads for damage before installation and replace if thread form is compromised.
