The GIBRALTAR 40705G is an equal double threaded stud with a 1/2-13 thread size and an overall length of 3.5 inches. This fastener features the same thread on both ends, allowing it to be threaded into a tapped hole on one end and accept a nut on the other. Constructed from alloy steel with a black oxide finish, it carries a Grade 5 material rating and a Thread Fit Class 50 designation. It also includes a flat for tool engagement during installation. This stud is used by mechanics, millwrights, HVAC technicians, and plumbers in equipment assembly, machine mounting, and mechanical connections requiring a stud-style fastener.
Equal double threaded studs like the 40705G are used in residential and commercial mechanical applications where a through-bolt is not practical. Common install scenarios include compressor mounting, pump flanges, equipment feet, and structural connections in HVAC and plumbing systems. The black oxide finish provides moderate corrosion resistance in dry or lightly oiled environments. The Grade 5 alloy steel construction provides the tensile strength needed for vibration-prone mechanical assemblies.
Designed as a standard 1/2-13 equal double threaded stud suitable for use in mechanical, HVAC, plumbing, and industrial equipment applications requiring a Grade 5 alloy steel fastener of this thread size and length.
Installation is typically performed by a licensed mechanic, millwright, or trade technician. De-energize and lock out all equipment before installing or removing studs in powered machinery. Use the flat provided to thread the stud into the tapped hole first, then secure the mating component with an appropriately rated nut. Follow applicable torque standards for 1/2-13 Grade 5 fasteners as specified by the equipment manufacturer or relevant mechanical codes.
