Gibraltar ST1-25-G Double Threaded Stud 3/8-16 2-1/2 in

Product Description

The GIBRALTAR ST1-25-G is an equal double threaded stud with a 3/8-16 thread size and an overall length of 2.5 inches. It is manufactured from grade 1117 carbon steel with a black oxide finish that provides moderate corrosion resistance in sheltered environments. Left-hand and right-hand threads run from each end to a center shank, making this stud suitable for applications where two components must be fastened from opposing directions without rotating the assembly. Plumbers, HVAC technicians, electricians, and general mechanical contractors install this type of fastener in equipment mounting, pipe support, and structural connection work.

This double threaded stud is used in residential and light commercial mechanical installations where a fixed, non-turning threaded connection is required. Typical applications include equipment base mounting, vibration-isolation bracket assemblies, pipe hanger rod connections, and panel or enclosure mounting points. The black oxide carbon steel construction suits indoor and dry-to-mildly-humid service environments. At 0.06 pounds per piece, the stud is lightweight and easy to handle during installation in confined spaces.

Key Features

• Equal double threaded design with left and right thread directions for two-point fastening without component rotation
• 3/8-16 unified coarse thread for broad compatibility with standard nuts and threaded components
• 2.5-inch overall length suits medium-depth mounting and connection tasks
• Grade 1117 carbon steel provides reliable tensile strength for general mechanical fastening
• Black oxide finish reduces surface oxidation and light corrosion in indoor environments

Compatibility

Designed as a standard equal double threaded stud for use with 3/8-16 nuts, threaded couplers, and tapped components in general mechanical, HVAC, plumbing, and electrical equipment installations.

Installation Notes

Installation is performed by threading technicians and general mechanics using standard hand tools and open-end or socket wrenches sized for 3/8-16 hardware. Ensure mating threaded components are clean and free of debris before engagement. Apply thread-locking compound or jam nuts as required by the application to prevent loosening under vibration. Follow applicable codes and equipment manufacturer guidelines for fastener torque and assembly requirements.
